There is a beta2 already, and a beta3 is likely to be tagged pretty
soon.
I have seen some new patches flowing in (mostly feature stuff, I
think) and I wasn't sure if those were eventually to be included with
Nagios 4 or not - possibly in a later release.
No major features have come in since the conference last year. Only
bugfixes, performance improvements and some code cleanups.
I've had good luck with the pre-beta versions of Nagios 4 and am
contemplating timing for a move to Nagios 4 (and Merlin).
Happy to hear it :)

I'd like to get patches with commit messages and proper author and signed-off-by info. Since we're using git for Nagios now, it'd go a long way in making sure everyone gets credit for the work they've done. The patches also need to apply cleanly to the latest master. You may want to clone the official Nagios repo, apply your patches on top of it and then send me a pull request for github or some such. git clone git://git.code.sf.net/p/nagios/nagios nagios-core should get you the very latest. If you apply your patches on top of 'master' and make sure to always do git pull --rebase when you want to get the latest and greatest you'll quickly see which patches either have been applied or which no longer *can* be applied. Then you can create a separate repository on github or some such and push the changes there. OK, we'll convert them into git changes based off master. However I'd like an assurance that the changes will be merged before we promise to convert. Style changes are fine, won't take much time and will not require retesting, but if we need to refactor object changes or make larger changes to logic, this will require retesting on our side. I'd like a reassurance that the time invested will result in a merge upstream, otherwise we're just wasting time for all of us. For instance, your assistance in the environment macros per-command was greatly appreciated and we've coded to the design agreed in the email conversations, but it hasn't been merged yet. It has, but it hasn't. The original patch no longer applies, due to extensive remodeling of the worker code. I still have it hanging around though, and I'm fairly inclined towards using it for services and hosts as well, so that environment macros can be set on a service level as well as on a command level. I've also been investigating the chances of doing this without resorting to setenv() (in essence, building a one-off block of the load-time environment macros, and then extending that whenever we hit an environment variable). But yea, I've got that one already. So I'd like to reverse the question and ask which changes are most likely to be accepted, based on the amount of changes required and we'll work through that list in order. Thread-safe calls It's harmless, and I'd apply it straight away if I had a sensible commit message for it, but I don't know why you need this so I can't really write one. While we're on the topic; Please write commit messages in imperative form and present tense, as if you're giving orders to the code for how it should change. Also give a short rationale for why it should change that way. The rules about not commenting out code you want to get rid of still applies though. It just looks terribly hackish when patches meant for upstream contains things like that. Slice services within hosts So long as it's configurable from cgi.cfg and the default stays the same as it is today I'll apply it immediately. It has no impact on loadable modules or other headaches, so that's a nobrainer, really. Check command by time period I feel this is somewhat lacking in efficiency and flexibility, and a much cleaner solution would be to add a filtering functionality to NERD so that checkresults can be shipped off to a third-party addon which can transform checkresults and plugin output as much as it likes. Failing that (which would be enormously cool but also a lot of work), I think it would most likely be best off as a separate module, with custom variables or separate configuration to support it. Supporting patches to run events when a timeperiod becomes active or inactive would still be welcome, obviously. Escalation via notification levels This is best off written as a module, using custom variables to configure it. If core support is required to block notifications to a particular contact, then such patches will naturally be accepted. The normal NEBCALLBACK_CANCEL return code signalling should work just fine for that. Synchronising state data Pretty invasive for quite a small benefit, and with enormous complexities to deal with to make this work properly. How do you handle reading the synced file while checks are in-flight and awaiting being returned to the mothership? They may have been spawned as a result of a bad checkresult on one node, but if the sync status returns them to OK and the in-flight result sets them as bad again, would that mean starting over on the retry-attempts? I see nothing in the patch that handles situations like that, so I'm forced to believe you haven't considered it. Considering the fact that full

In the same vein; Don't add commented-out code. * Avoid C++ comments. I know they're supported in C99, which I'm rooting for as the least version supported, but it's against the current style. * Don't mix spaces and tabs for indentation, unless it's continuation- indentation of a multi-line statement or condition. Stick to the style in the file you're editing, and *look* at the patch before you send it somewhere. * Avoid comments saying things like Opsview specific foobar if you want to have the patches included. If you *don't* want those patches included, don't send them to me or point me to where they are. It takes up a lot of time to remove crap like that, and I have no interest in cleaning up after anyone else. I'm messy enough as it is on my own. * Don't augment objects (such as hosts, services, commands) with new variables. Doing so means Nagios 4.1, and I can't take patches like that until Nagios 4 is at least released as stable. All objects have an 'id' field which means you can look up any extra data you want in O(1) time, provided you just initialize an array of size num_objects.$desired_object_type_in_plural before we enter the event loop. * Make patches the most scalable you can. For the check_time_period thing, you'd be far better off adding code to detect timeperiod changes, notice which timeperiods are used to change commands and make a one-off swap for all the affected commands as the desired timeperiod comes either in or out of effect. * Don't build on deprecated technology, such as external files for commands and/or check results. -- Andreas Ericsson andreas.erics...@op5.se OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 Considering the successes of the wars on alcohol, poverty, drugs and terror, I think we should give some serious thought to declaring war on peace. -- Get 100% visibility into Java/.NET code with AppDynamics Lite!

Hi Andreas Ericsson, I am not sure i understand Nagios 4 has improved performance *by a factor of 7* with Nagios 3 version. Does it mean performance improvement by 70%?. Correct me if i am understanding it completely wrong. 700%, in terms of the number of jobs it can spawn, according to a volunteer tester who reported in a few days ago. It's actually a bit inaccurate to talk about percentages, since most algorithms used in Nagios 4 are several orders of magnitude faster than the ones in Nagios 3, and that means they'll scale a lot better, but for very small installations you won't notice much difference except a slightly lower load. -- Andreas Ericsson andreas.erics...@op5.se OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 Considering the successes of the wars on alcohol, poverty, drugs and terror, I think we should give some serious thought to declaring war on peace. -- Get your SQL database under version control now!

[Nagios-users] svn - git conversion
As of today, the migration from subversion to git has been completed. The new git repository is still hosted at sourceforge. You can clone the repository using the following command: git clone git://git.code.sf.net/p/nagios/nagioscore and then browse the code locally in your own nagioscore folder. The svn repository will be decommisioned without further warning, so anyone who likes to stick to the bleeding edge of Nagios core should migrate to git ASAP.

On 2013-05-09 11:19, Steve Shipway wrote: Does anyone have an HA setup for Nagios that works? I'm thinking of creating a NEB module that will link two Nagios setups, and replicate over all status changes, config changes, downtime, comments, etc etc and then set the 'standby' Nagios to be checks/notifications disabled when in standby mode, and enabled when in active mode. Then put the two behind a failover load balancer (F5, Foundry or apache reverse proxy). However this would be too much work if someone else has already found an equivalent solution. I've looked at Merlin but it doesn't seem to do what I'm after (and the documentation is practically nonexistant - much the same as the NEB API documentation, in fact). Mod_gearman lets me have redundant checks and replicate *active* checks, but not commands, downtime or passive checks. Merlin would do exactly that if you set one of the nodes as a poller but having all hosts assigned to it. When the poller goes down, the master will by default take over checks for it. Merlin is actually pretty well documented, but as textfiles that you have to read the oldschool way. If there's anything you find lacking from the HOWTO document or the README, please let me know and I'll amend it.

But when I look at the actual .cfg file for the service escalation definition, there is not mention of the sms group anymore. I've checked, and re-checked and still I can't see why this has happened. There are three separate sensible explanations for that. You have, at some time in the past, created an objects.precache file and Nagios is restarted with being asked to use the precached file. Something regenerates the configuration behind your back, overwriting your changes.

I know it's fairly late in the dev cycle, but the current status of lib/worker.c simply isn't maintainable enough.

Using a hash- table to look up the command and its handler would be a very good idea indeed. Then we'd do the insert to hash-table thing as add_command(char *name, char *description, int (*handler)(char *cmd, char *args)) or some such and generate the help-list from that, while allowing nebs to access the same command parsing routines as the rest of Nagios. Though to be honest, I'd much rather just extend the query handler thing and let commands take key/value vectors via the socket. That way we can support multiline values properly and get rid of nonsensical attributes. FLUSH_PENDING_COMMANDS This has no meaning anymore, and if I guess correctly it never had, as it would be impossible to submit a command that flushes all pending commands, as any command one want to flush are either already parsed and processed when we get to this command, or hasn't been picked up by the command queue yet (in Nagios 3 that is; In Nagios 4 it has absolutely zero meaning). I'll remove this. CHANGE_HOST_NOTIFICATION_TIMEPERIOD This is undocumented for real, although its meaning should be fairly self-explanatory. DEL_DOWNTIME_BY_HOST_NAME DEL_DOWNTIME_BY_HOSTGROUP_NAME DEL_DOWNTIME_BY_START_TIME_COMMENT These are the new 'distributable' downtime delete commands, which I suppose are undocumented. CUSTOM_COMMAND This is currently unused, to the best of my knowledge. Its intended use is for eventbroker modules that want to accept external commands. There can't really be any documentation for it, apart from whatever the module itself decides to accept as input. Since the query handler got implemented (which allows for feedback from the targeted handler), this should be considered obsolete. I totally agree with Andreas, that it would be nice if there was a handler that could print commands, short description, and in an utopian world, the documentation would be generated from that so there is no need to maintain it manually. Well, it still needs to be maintained manually, since the description and the command template isn't going to write itself. It would just be a lot more up to date if the documentation was kept inline with the code. -- Andreas Ericsson andreas.erics...@op5.se OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 Considering the successes of the wars on alcohol, poverty, drugs and terror, I think we should give some serious thought to declaring war on peace. -- Free Next-Gen Firewall Hardware Offer Buy your Sophos next-gen firewall before the end March 2013 and get the hardware for free!

Most of the time it uses is spent in network latency because there's no way the shim can get the compiled binary to do all its work for it in a single session. check_wmi is one of the (very many) plugins where embedded perl wouldn't improve things in any way what so ever, and the only way to get real performance out of it is to rewrite the wmic binary so that it can handle communication with the perl plugin, or so that wmic itself is turned into a plugin. Where embedded perl *does* matter is for perl plugins that utilize a large set of perl libraries. For those cases, embedded perl can cut execution time of plugins down to as much as 25% of the original cpu and I/O cost. However, the new worker model is still up to 12 times more efficient than the old one, so at best you're looking at a tiebreak for running perl plugins. There are people using it so much (multiple tens of thousands of invocations per day) that they already notice the amount of CPU that it consumes. I'm sure they do, and patches to make language-specific workers work fine out of the box are ofcourse welcome, along with the code to make such workers fly. I'm hoping the op5 can assist with a solution to the Nagios 4 problem of no embedded Perl. It's not a problem that Nagios 4 has no embedded perl. It used to be a problem that Nagios 3 with embedded perl enabled leaked so much memory that the system became unusable after a day or two of running. This is (potentially) a performance issue caused by a single plugin being heavily used in spite of it being crap code that just wraps a second program. Why has it been taken out anyway? For all the reasons stated above. There are a lot of plugins out there that use Perl. And for the most part it's still faster to run checks with Nagios 4 without embedded perl than it is to run checks with Nagios 3 with embedded perl compiled in and enabled. The only exception is where large and heavy plugins written in perl are extensively and almost exclusively used, and the perl loadtime dominates the time it takes for the plugin to run. That's not the case with check_wmi. For a workaround, you may want to look into mod_gearman. It's one of the unofficially blessed eventbroker modules that are known to work well with Nagios 4, and as a happy coincidence it still supports embedded perl. I know for a fact that Nagios 4 with mod_gearman works very well, and if you put your perl-based checks in a single service group and let mod_gearman handle only those, you'll have a system that can easily handle tens of thousands of checks without breaking a sweat. As a final note; Embedded perl *may* yet come back to Nagios. If it does, it will be as a multi-stage rocket that goes like this: 1. Make Nagios recognize different script languages. 2. Make Nagios' worker process manager capable of distributing checks based on scripting language. 3. Build a special-purpose worker that supports perl caching and whatnot and get it included in Nagios. Given that it's done properly and the code holds good quality, I'd be more than happy to take patches that implements script recognition and a perl-worker. Note that the worker will have to be able to handle the case when plugins can't be executed by it since they don't conform to whatever rules the embedded perl layer chucks up. It will, however, *never* be in the plain core worker, which is meant to be as stable and simple as possible. -- Andreas Ericsson andreas.erics...@op5.se OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 Considering the successes of the wars on alcohol, poverty, drugs and terror, I think we should give some serious thought to declaring war on peace. -- Master HTML5, CSS3, ASP.NET, MVC, AJAX, Knockout.js, Web API and much more.

Re: [Nagios-users] Nagios Update Check Is Not Running

I noticed that the main.php page update_available blue flag never appears
for me when a new version of Nagios is available. I do have
check_for_updates=1, but I see the following at the top of the Nagios

info {

version=3.4.1
last_update_check=1340002591
update_available=1
last_version=3.3.1

What that tells me is that the Nagios function (that checks to see if
there is an update available) hasn't run since 6/18.2012 6:56:31 GMT
(1340002591). I am seeing similar indications on my other Nagios servers.
Yes. This is my fault. I'm one of the core maintainers, but I also take care
of maintaining the nagios package for op5. Pretty much the only thing we
change in our version is to disable update checks with a hardcoded return
statement in the function that issues the actual check, since our customers
get their updates from us in the form of RPM packages. Once upon a time a
patch spilled over to the Nagios repository that had that change, so the
update check was broken sometime between 3.3.1 and 3.4.4.
I believe it's fixed in 3.4.4 though, with kudos to Eric Stanley for fixing
the problem.
1) Is there a way to force Nagios to CHECK NOW?
Not that I know of, and it wouldn't work with the hardcoded avoid update
checks at all cost patch in place anyway.
2) Does the update_check log it's results somewhere?
Only in the status_file.
3) Do you have any recommendations on how I should approach this problem?
Upgrade to the latest version manually and then the update checks should
start working again.
I'm really sorry for the inconvenience.

Re: [Nagios-users] Embedded Perl in Nagios 4
On 12/18/2012 09:29 AM, Samuel Kidman wrote: Hello I just had a look at Ethan's slide decks on Nagios 4 from 2012 Nagios Conference, and found out that embedded perl won't be in Nagios 4. I'm running a distributed Nagios deployment that makes extensive use of perl plugins, and the performance of my Nagios servers is beginning to struggle a bit as a result. I was working on making my plugins work with embedded perl but since this is now not an option I was wondering what others will be doing to optimise perl plugins without embedded perl? For starters, you should just upgrade and it's entirely possible that the performance issues go away completely. Nagios 4 has awesome check scaling. The second thing to do would be to look into running mod_gearman with workers living on the same server as the master Nagios process. mod_gearman still has embedded perl support (although it really only makes a difference for large plugins). The third thing to do would be to inspect your most expensive plugins (expensive in terms of Perl loadtime multiplied by the number of times the plugin is used for any given time interval) and see if rewriting them in a different language makes a huge difference. We did that for the snmp interface checks when one of our large customers wanted to monitor some 6 services. Perl simply wasn't fast enough. Embedding it meant we couldn't fork() fast enough (embedding languages has its own overhead too), and it still leaked memory, so we rewrote them in C and we cut system load by more than 85%. The fourth thing to do would be to either sponsor a developer or buy development time to build a special-purpose Nagios worker that handles perl checks and that has a perl interpreter and a cache embedded. It's not certain that would be better than just running the perl interpreter directly. Without a cache, embedded perl is completely useless, since it still has to bytecompile all the modules, and with it it can grow to consume all memory on the system, no matter how carefully you write your plugins. Tradeoffs, compromises and possible leaks no matter what you do if you start down that route. It might be awesome though, so I guess it could be worth a shot. -- Andreas Ericsson andreas.erics...@op5.se OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 Considering the successes of the wars on alcohol, poverty, drugs and terror, I think we should give some serious thought to declaring war on peace. -- LogMeIn Rescue: Anywhere, Anytime Remote support for IT.

If I happen to send a reload (HUP) to nagios while a service check is in progress (fairly easy since my service check is rather long lived), the reloaded nagios doesn't seem to know about that service check and so I'll end up with another being scheduled as well as the original on its schedule. Create a dummy service check that just sleeps for 30 seconds or something and issue a reload while it is running and see if your nagios instance will start another sequence of service checks. This should be pretty easily fixed by just adding a check reaping event before initializing the event queue and skipping all checks that have already been scheduled. I'll have to add a check for it in 4.x. Since we keep workers between reloads, the same thing can easily happen there. That means we'll reschedule all checks like normal when we're starting, but if a check result comes in when a new check is already scheduled, we'll remove the old event and reschedule a new one according to the retry interval. I'd suggest doing something similar in the 3.4.x branch, but I'm not sure I can commit to that one without doing a new svn clone, and that takes at least a day. Mark; Would that be acceptable to you?

Apparently in contact definition the contact_groups disappear and it come
with an empty line.
In objects.cache the contacts are always written to the contactgroup's

not, then there's something seriously wrong.
Im preparing the box to send privatly login data so you can check by yourself.
Much appreciated. Many thanks.

The only contactgroup i can see in object.cache
I did send you a private mail with login data for the box.
You did, and I'm perplexed.
The problem arises when precaching objects (which is discouraged in
Nagios 4, since it actually makes config loading slower rather than
faster for almost all cases).
The objects.precache file has you as a member of the contactgroup,
but the objects.cache file does not.
If I don't precache objects, it doesn't matter how I specify that
you should be a member of the group. You still get notifications.
If I do use the precache file, you don't get notifications no matter
how I specify it.
Now that I noticed this discrepancy, it appears there are other
issues with group membership parsing as well, and they only appear
when reading the precached object file. I'm working on a patch as
we speak and it appears I've got things fixed. I'll just run some
more tests and then send it out muy pronto.
Thanks for letting me sneak a peak at your server. This one would
most likely have baffled me for quite some time otherwise.
This should sort out many of the Nagios doesn't send notifications
issues that have cropped up here and there and that I've been unable
to reproduce.

Any suggestions/hint?
So contactgroup is inherited from template. That might be a clue. Can
you verify if the contactgroup is present on the proper services in
your objects.cache file?
Also, if you're not keeping secrets in the configuration, it would

Lets say that I have a lot of important infrastructure behind switch-4 and switch-5 and that the normal stp way is to route through switch-2 for switch-5 and for switch-4 to switch-3. Lets also suggest that at switch-2 there is not that much important infrastructure. If now switch-2 is failing at the same time a really important infrastructure behind switch-5 fails. I will only get informed that switch-2 failed, because switch-5 is a child of switch-2, but I will not be informed about the more important stuff at switch-5. Now I will spend a lot of time to exchange switch-2 before I even find out that there is something really important at switch-5 going on only because I could not give it a second parent (switch-4). Maybe the other problem would have been fixed in minutes if I would have known about it. I think it is a bad idea to have such parent/child chains. And please keep in mind that this is just a simple example and that a network can be much bigger than just 5 switches. The other point is that I will never see the real network infrastructure in the statusmap. As far as I can read the documentation I should also be able to build up my whole infrastructure like it is in the statusmap. Or for what is it at all? parent/child relations are primarily to block notifications for stuff that is only down because some earlier stage in the traffic shoveling is down. I would be really pleased if somebody could answer my question. - - Why is it in nagios not possible to be parent/child of a other host at the same time? - - Why is it a deadlock and where is the problem?

Hello. Has anyone come up with solutions for processing Nagios performance
data on a server other than a Nagios server? We've been processing perfdata
results on our Nagios server(s) for a while now and increasingly it's just
eating up too much I/O to make me comfortable.
Yes, we do use rrdcached and yes, I realize that shuffling data around on
different disk spindles and controllers would help, but in today's world
where companies don't like building any kind of physical server let alone one
with all that additional hardware, that's not entirely an option for us.
I realize that once the perfdata files are on the dedicated graphing
server(s), processing them into RRD files there should be a no-brainer. My
problem is figuring out how to get them there without say, using a NAS
device. (If I/O's a problem locally, I don't want to shuffle that I/O to an
even slower network device).
It would be ideal if somehow there was a process that I could just send that
data to and have it picked up remotely. Like if maybe Merlin have a special
kind of peer that just received a stream of perfdata or something. Anything
else I could imagine would be some kind of home-grown solution like say
pumping events into a messaging system from the Nagios server(s) and then
letting the graphing server pick them up from the message queue(s). I could
also imagine some kind of fancy-pants module in Nagios 4 that did something
like this, maybe.
Any thoughts would be appreciated.
Using the NERD radio you will be able to stream your checkresults
off-site (once the macro-processing patches are done, that is). It's
Nagios 4 only, but I know you've been looking at that already so
perhaps that's not be a big issue.
The will be is a bit of a showstopper though, but I have to have
it done by next wednesday.

On 10/03/2012 05:58 PM, Frost, Mark {BIS} wrote:
Dan,
As I understand it, the issue is less about Nagios and more about
npcd. Nagios merrily produces the perfdata files and then npcd
comes along and scoops them up, but as it's processing them it's
opening a lot of rrd files and inserting data into them.
That's what rrdcached is for. It's supposed to stash the perfdata
in memory so writes don't have to happen so often. You defeat the
purpose if you use a cache-timer shorter than your check-interval
though, but if you have, say, a 30 minute cache time and a 5 minute
check-interval, you basically cut I/O down to 1/6th of the normal.
If you also hook up a decent-sized ssd, you get x21 throughput
from before, so all in all you can get a rough increase of 12000%
with both those options enabled.
So really
it's npcd that's the problem. Well, not really a problem, but
ultimately it's doing its thing and then Nagios gets less than a fair
share of the box's I/O. It's not that it's horrible right now, but
we're starting to notice it and I would tend to be concerned about
scaling problems.
Honestly even with Nagios 3, it seems like Nagios' own I/O is
entirely manageable so far with strategic use of ram disk. It's
just putting Nagios and PNP4Nagios (plus Apache to serve up the graph
contents which I'm also not happen going on on the same server) on
the same boxes that I don't like.
With Nagios 4, set status_file=/dev/null and use livestatus instead
and you're golden. Apart from the nagios.log, there's no other I/O
going on from Nagios' side, so it won't get stuck waiting for pnp to
get done.

Re: [Nagios-users] nagios writing escalation rules multiple times to objects.cache
On 10/01/2012 09:37 PM, Chris Baldwin wrote:
Short version:
I have an ever-growing Nagios install for monitoring a bunch of linux
hosts (currently 99 hosts 2322 services, I plan on adding 115 more
hosts 1500+ services). I've noticed something odd with my escalation
rules - they're being repeated multiple times in my objects.cache file.
This is started to affect performance for parts of my nagios install, to
the point where it's painfully slow to use the web interface.
My google-fu is weak today, so I was hoping someone here could point me
in the right direction.
Longer version:
I have 4 escalation rules:
-Our helpdesk gets notification #1 for critical issues.
-Our on-call person gets notifications 1 - 12 @ 5 minute intervals 24x7.
-The relevant IT-group leader(s) get notifications 5-12 @ 5 minute
intervals during on call periods.
-Our CIO gets notification 12 - infinity at 60 minute intervals during
on call periods.
We use puppet to control our environment, and it's amazing for deploying
servers and adding them to nagios. Once I'm able to bring in other
aspects of our environment under puppet control (firewall, sudo, yum
repos), it will be trivial to set up a server from scratch and monitor it.
In order to create a new set of escalation rules, we use a custom class
on the puppet server and a small bit of code to be executed from the
client-side (of puppet) to make this work. An example:
# Escalate to the_boss. He, in turn, will call people. I
imagine this
# to be along the lines of Hulk nudging Thor playfully in The
# Avengers. And sending him flying through a few bulkheads.
nagios::server::escalations { Boss-critical:
contact_groups = the_boss,
escalation_options = c,r,
escalation_period = oncall_hours,
first_notification = 12,
last_notification = 0,
notification_interval = 60,
servicegroup_name =
Disk,Ping,HTTP,Load,MySQL,Ping,Procs,SSH,Swap,Users,Zombie,
}
I know this portion works correctly - it's producing my desired result,
which is 1 file per (set) of escalation rules specified. I have 1722
escalation cfg files.
The cfg files look something like this:
define serviceescalation{
contact_groups the_boss
escalation_options c,r
escalation_period oncall_hours
first_notification 12
host_name my.hostname.xyz
last_notification 0
notification_interval 60
#service_description
Disk,Ping,HTTP,Load,MySQL,Ping,Procs,SSH,Swap,Users,Zombie
servicegroup_name
Disk,Ping,HTTP,Load,MySQL,Ping,Procs,SSH,Swap,Users,Zombie
}
So you're assigning it to a host_name along with a set of servicegroups.
I'm not entirely sure that makes 100% sense, since servicegroup members
already have a host_name.
It might work better with Nagios 4, but I'm not sure. If it doesn't,
I'll fix it so 'service_description' is required when 'host_name' or
'hostgroup_name' is set, as I don't see how one makes sense without
the other.
My questions to you guys:
- Am I crazy to think that it's reading every rule once for *each*
server?
It seems as if it's reading the rule once for each host mentioned in
host_name and then assigning it to each member of the servicegroups
listed, so if you have identical escalations assigned to the same set
of servicegroups then this is really how you're configuring your
Nagios.
Nagios 4 has provisions to compare slave objects and avoid adding
multiple ones, which would hide a potential bug in your config. It's
currently only used for dependencies, but making it work with
escalations too would be the final fallback to fix this.
However, I urge you to look over your configuration first to make
sure you don't really have multiple escalations assigned to the
same set of servicegroups.
I tried using the precache, it didn't help. Both files were created by
my nagios install.
That's not surprising, as precaching and caching uses the exact same
code.

On 10/02/2012 02:52 PM, Marki wrote: Hi there, I'd like to further discuss http://tracker.nagios.org/view.php?id=177 which is about host object declarations. You suggest using host_name as something that resolves. However, we don't have a (DNS) hostname for each device. I'm suggesting what now? The only thing I'm saying in that bugreport is that Nagios does not and will not complain when the address fields of hosts are unique. Also, directive description (Nagios documentation) says: This directive is used to define a short name used to identify the host. The description for the address directive actually needs something useful, again, see http://nagios.sourceforge.net/docs/3_0/objectdefinitions.html#host You say one should switch to using them differently, i.e. host_name = ip address or DNS hostname alias = description because Nagios4 will do it that way (and Icinga already does). Nagios 4 won't do that. The one and only change in Nagios 4 is that address will be set to the host_name variable if no address field is set. That means people who want to use dns names for their hosts don't have to write that info again in the address field. I guess I will then try to update my config that way: - use a DNS name (if one exists) in the host_name field, otherwise use the IP as host_name if there is no reverse lookup for it, - in that case I use a symbolic name in the display_name field, - and optionally a description in the alias field. Furthermore for devices that have no IP but should show as different hosts, define a virtual hostname with the IP address of the device's management station (that may be duplicate). You can't have two hosts with the same host_name. You really don't need to change anything at all to make your configuration work the same way it always has. Anyway I'd really like to know what everyone thinks about this, and how you do it in a sensible way. host_name is the short symbolic name that has to be unique but can be anything you want. address is the field that (usually) has to point to an ip address or that's resolvable as a dns hostname. display_name and alias are equally useless and are only meant to provide some sort of help when receiving notifications or when viewing the UI. You've been overthinking it and seriously misunderstood something. The way you think Nagios 4 will be working isn't correct. -- Andreas Ericsson andreas.erics...@op5.se OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 Considering the successes of the wars on alcohol, poverty, drugs and terror, I think we should give some serious thought to declaring war on peace. -- Don't let slow site performance ruin your business.

The only thing I'm saying in that bugreport is
that Nagios does not and will not complain when the address fields of
hosts are unique.
In fact you also said:
that suggests that either your namestandard (used for the host_name field)
sucks, or that you or your co-workers are simply confused when it comes
to configuring Nagios.
So let's talk best practices.
In practice it did occur that when someone copy/pasted a bunch of service
definitions (yeah I know you should use templates, call that confusion if
you like) just forgot to update the address field and the newly created checks
(or so they believed) did nothing more than check the old stuff once more.
So use the require unique address scriptlet I provided in the ticket.
Nagios won't protect you against such config buglets, because for many
users its a very useful trick to do.
According to what you suggest, it is wisest to indeed use DNS names where you
can in the host_name field. (and only use the address field in special
circumstances) (in Nagios4)
Or just not fsck up when adding hosts, perhaps?
If you define your nomenclature like that, possible confusion may be
eliminated ;-)
Could be.
BTW I have all sorts things in place that
- check for duplicate addresses
So this should've been caught then.
- check for syntax errors all over the place
Which Nagios already does for you, so that seems moot.
- check if the plugin specified in command_line actually exists thus
preventing
stupid error 127 or alike
You don't get that anymore. With Nagios 4 you get
(No output on stdout) stderr: execvp() failed. errno is 2: No such file or
directory
PS. As a sidenote: I once created a more or less functional version of a
script
allowing to change service names. It's not trivial but can be done.
Does anyone know of something existing and working that allows to change
service and also hostnames?
Well, python, perl, ruby, php, sed, awk, whathaveyou can do that with
little or no hassle, so long as you know how to parse compound blocks
into key/value vectors (which is trivial).
Unless you're talking about modifying it runtime, in which case it's
a little trickier and requires an eventbroker module.
for f in $(grep command_line $NAGIOS/etc/checkcommands.cfg | awk '{print $2}'
|\
grep USER1 | sed 's/\$USER1\$\///'); do
if [ ! -f $NAGIOS/libexec/$f ]; then
echo [KO] $f does not exist
ERR=$(($ERR + 1))
fi
done
[ $ERR -eq 0 ] echo [OK] all commands seem to exist
This seems pretty error-prone. I've been thinking of adding something
similar to the Nagios binary, to make sure all (used) commands have
existing binaries and warn if some of them don't. It would be quite
trivial, but I haven't gotten around to it yet as not that many people
suffer from it for very long. Besides, with the special-purpose workers
on the way it's quite likely we'll just trigger false positives by the
dozen.
# make sure to always update both statements!
if [ $(grep -r address $NAGIOS/etc/hosts* | grep -v '~' | grep -v svn |\
grep -v '.bak' | cut -d: -f2 | tr -d ' \t' | awk -F'address' '{print $2}' |\
sort | uniq -c | sort -n | grep -v ' 1 ' | wc -l) -ne 0 ]; then
echo [INFO] IP address defined more than once:
grep -r address $NAGIOS/etc/hosts* | grep -v '~' | grep -v svn |\
grep -v '.bak' | cut -d: -f2 | tr -d ' \t' |\
awk -F'address' '{print $2}' | sort | uniq -c | sort -n | grep -v ' 1 '
else
echo [OK] Dup IP check ok
fi
That's just insanely tricky. precache the objects and you can use
grep address $precache | sort -k 2 | uniq -c | sort -n | grep -v ' 1 '
instead to list all the duplicate addresses.

I still see that as a misfeature. I would rather have the preflight
check tell me there's an error because I forgot to define contacts
for the service than for it to assume that what I want is anything to
be inherited from a host definition. I'd be OK if that were the default
behavior and was configurable, but I'd be the first to disable that
in nagios.cfg if it were a configurable preference. Yeah, I know,
patches gleefully accepted :-).
Well, disabling object inheritance completely is pretty simple. Doing
it on a per-variable basis is less so.
I'm on the fence with this. On the one hand I really don't care what
the default is. On the other hand I really don't want bugreports from
people who're relying on that feature and suddenly realize it's gone
missing.
As a workaround for your particular case, you could specify a catch-all
service template which other service templates reference, where you set
contactgroups and contacts to something that doesn't exist. That way
you'll get your error and I can dodge bugreports ;)

[Nagios-users] Service parents...
... have arrived.
The intention (and the way they currently work) is that they remove
the need for servicedependencies like this:
define servicedependency {
host_name A
service_description Foo
dependent_host_name B
dependent_service_description Bar
notification_failure_optionsw,u,c
}
Currently they totally ignore state hardness, and only care about the
actual state. You can have parents residing on a different host (in
which case you have to specify host_name,service_description in the
parents field, naturally), or you can have same-host parents, in which
case you only need to specify the service description. This only works
so long as there's only a single parent though, but since that's how
99.9% of the servicedependencies seem to work in the configurations
people sent me after my Call for configs, I guess that's reasonable
for a first implementation anyway.
Speaking of which; Thanks a bunch for the configs. You know who you are,
although some of you didn't want me to name you in any thank-you's, so
I'll refrain from posting the full, and surprisingly long, list of people.
Your help was invaluable and helped me uncover many a bug that would
otherwise have earned me a lot of hatemail.
For the (extremely) common depend on a client version check thing,
that would look something like this:
define service {
usesome-suitable-template
host_name A
descriptionNRPE Disk /
parentsNRPE Version Check
}
although I expect you crafty folks will put such things in templates
and be done with it very quickly.
Enjoy.

When a program catches a signal, it returns the sigid as a negative number, but the field for the exit status is unsigned, so it gets translated to 128 + sigid instead. As I read it back, I realize that doesn't exactly make supersense to anyone not familiar with integer math as computers do it, but I can assure you that's the reason. When you get exit code 127 or 126 (below 128, but high), it's because execve() has thrown an error and the shell is trying to signal it the only way you can. It does that by returning 0x80 and subtracting the error number. 128 is 0x80 and would be a negative number (which are reserved for signal-triggered exits), so 127 is 0x80 - EPERM, which means the Nagios user lacks execute permissions for the file. 126 is 0x80 - ENOENT, which means the plugin doesn't exist in the path specified, or one of the elements in the path leading to the plugin is missing.

Points will be given on: * Accuracy of bugreport. If the bug is triggered by one of 13 trillion serviceescalations, you'll have an excellent chance if you produce an example config which reproduces the problem without creating a huge overhead. * Patchiness of bugreport. If the bug contains valgrind output showing illegal memory access, or a backtrace of the error, it will be given extra credit. If it contains a minimal setup displaying the error as well as a patch fixing the error, you're almost sure to be in the very small Circle Of Winners. * Surgeonry of bugreport. If a patch fixes a billion unrelated items, points will be taken from it. * bugreports of a slow Nagios accompanied by gprof or valgrind output output will be given priority over other bugreports of a slow Nagios. Note that only bugreports providede *before* 2012-09-24 will be considerered, and also note that the winners will be announced at the Nagios World Conference 2012 (unless they explicitly ask me not to mention their names, in which case they can't even compete, really, but will probably get several shots from me if I ever meet them and *may* get a very special prize anyway).

command_line$USER1$/check_http -S -I $HOSTADDRESS$ -f

Of course I have changed the actual domain to example.com in the above.
But you forgot to change it in the apache log ;)
The alert report:
* Nagios 3.2 *
Notification Type: PROBLEM
Host: webwork
State: DOWN
Address: 131.162.201.91
Info: Server answer:
Date/Time: Wed Sept 12 06:59:04 ADT 2012
Here is a sample visit from nagios in the webwork apache log file
before this time.
XXX.YYY.2.50 - - [12/Sep/2012:06:58:50 -0300] GET
https://webwork.acadiau.ca/webwork/ HTTP/1.0 200 5015 -
check_http/v1.4.14 (nagios-plugins 1.4.14)
Our apache logs show nagios is visiting every 3 minutes, 24 hours a day. None
of these visits results in an error.
In a nagios log, this is all that appears for webwork for the day:
# grep webwork nagios-09-11-2012-00.log
[1347246000] CURRENT HOST STATE: webwork;DOWN;HARD;1;Server answer:
[1347246000] CURRENT SERVICE STATE: webwork;Webwork Web
Service;OK;HARD;1;HTTP OK: HTTP/1.1 200 OK - 4053 bytes in 0.274
second response time
So according to these two, the service (which you're saying never
turns OK) is OK, but the host itself appears to be down. I think
you need to rethink
If I do the check_http manually, I seem to get through fine:
# /usr/lib/nagios3.2/libexec/check_http 0-S -I webwork -f follow -w5
-c 20 -t 60 -u https://webwork.example.com/webwork
HTTP OK: HTTP/1.1 200 OK - 5162 bytes in 0.025 second response time
|time=0.024700s;5.00;20.00;0.00 size=5162B;;;0
Can anyone spot a reason why this alert is not set up properly or
there is a better way to do it?
Examine the *host* check, not the service check, if you want to figure
out why the host appears to be down.

[Nagios-users] Heads up for config changes in Nagios 4
Currently, with Nagios 3, it's possible to have cyclic group includes,
like this:
define hostgroup{
hostgroup_name HG1
alias Hostgroup 1
hostgroup_members HG3
}
define hostgroup{
hostgroup_name HG2
alias Hostgroup 2
hostgroup_members HG1
}
define hostgroup{
hostgroup_name HG3
alias Hostgroup 3
hostgroup_members HG2
}
With Nagios 4, that will generate an error. Currently the behaviour
is that the first hostgroup, as determined by alphabetical sorting,
will get the members of its included groups, but the later ones in
the sorting will not get the members of the previous ones, which is
surprising to say the least.
This will work the same for all grouptypes.

[Nagios-users] Call for configs
Hi everyone. Sorry for crossposting. As some of you may have noticed, the Nagios 4 development is well under way and introduces some changes in how we parse object config. Primarily in order to make it a whole lot faster, which it's in dire need of at the moment. Anyways.. I'm looking for Nagios configurations to help me verify that what I'm doing isn't breaking anything with regards to object config. I could generate configs (and I have), but there are so many various options that I can't possibly create all possible permutations that work all possible features of the Nagios configuration, so I've decided to fall back to lazy mode and see if anyone wants to step up and send me their configurations directly. I've created a small scriptlet that will let you anonymize most of your configuration, which can be downloaded from here: http://dl.dropbox.com/u/83439435/scripts/nagios-anonymizer.sh It won't replace your *_name variables, because doing that in a sensible manner requires individually hashing all of them and then replacing them with their hashed versions, and verifying a config like that is just a huge pain in the butt, but addresses, email addresses, pager numbers, aliases and all command information is wiped completely clean. The resource.cfg file isn't even included, so any and all passwords or secrets stored there will be left where it is.

[Nagios-users] Just a heads up
Sorry for cross-posting. I just committed and pushed out the worker process changes to the Nagios core. They've passed basic testing and are more than ready for a wider audience. If you're using active checks in your network you should be seeing a huge increase in number of checks executed per second as well as reduced I/O load, memory usage and cpu usage on your Nagios server. Anyone interested in beta-testing should grab the latest svn trunk and get busy. Also... I'll be going on vacation tomorrow, so I'll be slacking enormously on patch review and my other co-maintainer duties. Live with it. It's just for three weeks, so I'm sure you can manage.

Now we have our own script to send out the notifications. And,
apparently, custom variables are not exported outside Nagios for

That's $USER..$ macros, and they're not exported in the UI for
security reasons (although some of them find their way there anyway
through plugin output).
To give an example of when we’re able to get the var data: my
$o_hostname = $ENV{NAGIOS_HOSTNAME};
And this one doesn’t return anything: my $o_hostfunction =
$ENV{NAGIOS__HOSTSERVERFUNCTION};
First of all, you'd be better off not using environment macros at
all. When you do use them, Nagios has to calculate ALL macros
instead of just the ones you use, and some of many of them are
quite expensive.
Secondly, try replacing your script with something that echoes the
output of 'set' and 'env' to a tempfile and see what you get there.
It's possible the documentation regarding their names is wrong.

That is creating a new thread, by changing the subject and body. Or am I completely missing something? I do sort by thread on my machine and my emails are perfectly sorted. Perhaps you should start sorting my subject instead of X-header or whatever you are threading on now. I would love to have learned something about what you are talking about, but so far, you haven't explained a thing, merely complained.

If you have a problem with a persons actions, You should have taken the reply immediately offline, and not sent it to the group. You should also explain why doing what I do causes a problem, and not assume that what I do is intentional to cause a problem. Maybe I am not born with all knowledge and experience in all things mailing list known to man, as you apparently are. Some people try to teach and share knowledge.

BTW, You are the first person ever to have mentioned that doing it this way is causing a problem. I'll keep the thread here instead of taking it offline. This way if anyone else does what I do, we can all learn why this causes a problem. Maybe, we can get the owner of the mailing list to place a link or footer in each posting that says what address to send emails to. Then people like I who don't know, could just copy and paste that email address into new emails instead of hitting reply and changing subject and body and letting it fly. That is a fairly common thing in newsgroups postings, probably for this exact reason. I eagerly await your instructional and helpful reply. And here it is: When someone mentions, without malice, that you've done something wrong, examine your actions closely before claiming that those educating you are ignorant or wrong. If you can't find any fault in how you did things, ask nicely for an explanation. It's quite likely others know something you don't, and unless you actually *are* the reigning deity on the subject at hand, showing some humility is always a good idea.

Maybe some other users can chime in on this, but my understanding was that compiling with the embedded perl option tends to be problematic due to memory leaks and other unpredictable behaviors. (??) It is, most of the time, but the code is still in there so it's sort of supposed to keep working. Personally, I'd rather remove the whole thing, since it's such a mess 99% of the time. -- Andreas Ericsson andreas.erics...@op5.se OP5 AB www.op5.se Tel: +46 8-230225 Fax: +46 8-230231 Considering the successes of the wars on alcohol, poverty, drugs and terror, I think we should give some serious thought to declaring war on peace. -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Hi all!
I would like to know if there are any plans for the nagios v 3.4.x.
It has been a while since the last release so I was very curious about it.
There is. Nagios 3.4 will be a single-threaded and event-driven application
that sports an I/O-broker and vastly improved check performance. In essence,
we've removed 2 fork() calls, 4 disk searches, 2 filewrites and 2 filereads
from each check being performed. There's also a fixed usage of the current
scheduling queue implementation which turns scheduling new checks from its
current O(n) behaviour to O(1). This will provide a huge benefit for large
installations, and combined with the worker process code we're currently
seeing a 12-fold increase in the amount of checks Nagios can execute, but
it's still too early to tell what other things are affected. The external
command pipe might be a bottleneck if one uses large amounts of passive
checks, for example.
It's currently in late alpha, so beta releases should be available in a
month or so.

Andreas,
I'm a little confused about this. I've been eagerly awaiting these
gee-wiz-bang space-age changes, but when I looked over the change list
for 3.4.0 that Ethan sent they seem like mostly minor changes. Or
perhaps they just don't describe things in enough detail to match up the
rather significant architectural changes listed above.
Is this the super-summarized bullet item that refers to the change above?
ENHANCEMENTS
* Use execv() to execute active check commands (#86 - Ton Voon,
dnsmichi)
Nopes, it's not, and that patch is actually broken. My code still leaks (about
1MB per 24 hours with 1000 checks / second), so I've held it back a bit. I
didn't know they were going to hit the release button so fast, and without a
beta period.

Re: [Nagios-users] Any upcoming release?
Bleh. It's too late and to sit up and rebase 160-odd patches on top of
20 to fix a single broken one.
For those using the 3.4.0 release, I've cherry-picked all patches that
went in the 3.4.0-release apart from the broken execvp patch and added
them on top of the worker-process code.
If anyone's interested in trying them out, you can get them from
git://github.com/ageric/nagios.git or possibly get a snapshot somewhere
at https://github.com/ageric/nagios
Consider it 3.5.0-alpha or something. It still needs a lot of testing,
but it's been ticking along quite nicely in our lab the past 4 months,
running checks and generally just working with livestatus and Merlin
enabled.
Granted, that part of our lab doesn't use passive check results, but
most of the rest is tested and known to work pretty well, apart from
the small memory leak mentioned below (but who knows? Someone might
even fix that now that it's in the open).
Happy testing.
I'll get a proper fix in for the double-quote issue on friday, as I've
got presentations to run all day tomorrow.
