Re: [Nagios-users] Dynamic warning/critical thresholds
As indicated, make a plugin that gets the info and set thresholds so high they're never likely to ring the red bell. But in addition to this, I'd set it up with something like nagiosgraph to generate graphs that you can watch. This will save/show historical data and show you the norm. Thus you may wish to then set a threshold at a later date based on this empirical data. If you don't want to go to the trouble of nagiosgraph, your plugin can still email you when the rate reaches a threshold you define (again, without setting off nagios warning/critical alarms) On Tue, Jul 10, 2012 at 10:28 AM, Jonathan Gazeley jonathan.gaze...@bristol.ac.uk wrote: On 10/07/12 14:47, C.

Re: [Nagios-users] Hostgroup Members
Actually, that raises an interesting tangential question.
Can/should your nagios server handle mail delivery to
many many people? Unless it's tuned for higher capacity
email delivery, I'd expect SMTP functions to negatively
impact nagios checks.
In other words, why not just use a single address that
points to a listserver that can better handle delivery
to larger groups of people.

Hello,
We are using a fairly old version of Nagios (1.4.1) which has been running
great for years and is in production on 100+ servers so we are a bit hesitant
to update. If it ain't broke don't fix it, right? Anyway, one minor problem
is the fact that in the nagios configuration, the members directive for a
hostgroup can only support a certain number of entries, due to the fact that
the members directive takes a comma delimited list of members and that list,
it seems, can only be a maximum of 2000ish (I think, I don't recall off hand)
characters. Like:
hostgroup {
...
members = Member1,Member2,Member3,...,Member200, Member201, Member202
}
My question is, do newer version of nagios remove this limitation? It isn't
really a huge deal since we can simply create additional hostgroups when we
reach the limit on one, however if this is fixed in a newer version then
that, for us, would be a good reason to upgrade.
Thanks,
Brandon

Re: [Nagios-users] Better way to check Cisco switches?
Nagios is a phenomenal tool but isn't necessarily a silver bullet. Nagios does try a certain number of times before a soft failure becomes a hard failure. This can be adjusted. Also, many people have replaced a very tight check_ping with check_icmp and looser return times. But in general, you might wish to monitor a manageable switch with something else. Indeed snmp is an excellent way to go. You'll then need to figure out some way to manage the snmp messages though. One way might be to search for interface down messages where it doesn't come back within a period of time.

Re: [Nagios-users] Monitoring who is connected to Samba share
I don't know of any plug-in but you can roll your own.

I believe this also shows login times For a more generic solution (if you don't want to run samba and join the domain), I've had some luck with the sysinternals tools, psloggedon. I set up a scheduled job on a windows host that searches all windows hosts for logins and dumps the output to a share I can see on the linux side. A linux host then parses the crap out of this and makes a nice web page. Ugly, but it works.

Re: [Nagios-users] Nagios configuraion best practice
I think this is more a personal (or site) preference.
But using host groups can be very useful to eg
insure that
all windows machines get thus-and-such service checks
all RedHat machines get thus-and-such service checks
etc
In other words, a wildcard or hostgroup tag for a service check
can substantially reduce the size of your config, make it
more readable and insure uniformity.
From a grouping perspective, ie if you tend to display by
hostgroups, it's often helpful to list all hosts once and only
once. However, in other environments, some find it very useful
to list some (or all ) machines in multiple groups.
This would allow you to easily view all RHEL9 hosts,
SLES10 hosts that have not yet been updated, hosts in room 123,
etc. The downside of this is when hosts go red, you'll see a lot more red...

Would it be an idea to as much as possible use this configuration method:
hosts --- hostgroups --- services? To elaborate some: Hosts are always
connected to host groups, and the same for services. This way one will
avoid linking services to specific hosts, making the service definitions
more clean.
Also, I'm thinking about having a host group called for example
linux-servers, to which all linux servers are linked. A number of service
checks common for all linux servers are also linked to this host group. When
adding new linux boxes I simply link them to the linux-servers host group,
and add extra services checks where needed. In a similar fashin I would
create a host-group called for example dell-servers to which all Dell
hosts and related service checks are linked. New Dell servers are then
linked to this host group.
I'm thinking this may be a good idea, but would like to hear how others have
structured their configuration and if there may be some hidden pitfalls in
my proposed configuration method.

Re: [Nagios-users] checks per host
As pointed out, normal depends on your environment. Some sites only check a handful of things per host; some check more. The bigger issue is if your server can handle the number of checks and in a timely fashion. Look at nagios parameters Max_service_check_spread, max_host_check_spread as well as the various params for individual services such as check_interval If you have a check that takes a long time to complete, you'll probably want to run it less frequently. If the client were Unix, not windows, you'd have the luxury of being able to run the check on the host in question. This can be done either via cron and have it generate a status file that nagios then checks or using NSCA.

[Nagios-users] read-only nagios
We're looking for a mechanism to allow others access to our nagios server for viewing only. The kicker is they want to be able to reach it without any htpasswd so multiple htpasswords and authorization_for_system_commands is not an option. I'm thinking the only practical method to accomplish this is to somehow mirror the install elsewhere. One idea was a cronjob that ran a wget hitting the status cgi and dumping it somewhere on the same machine. This still tends to have authentication queries embedded in it. Another option might be another install on the same server, different port, no authentication and perhaps rsync'ing data from the master. Has anyone set up anything like this before?

It seems that all options will run up against the fact that we have enabled web authentication and are not willing to turn it off. I've come up with a couple of ideas however. 1/ create a htpasswd account called guest with no password. At least that limits the necessary typing/authentication 2/ You can encode a username/password combination into a URL. This can also work with a redirect. So if I have an htpasswd account named open, password open, I can point people to a URL containing this: META HTTP-EQUIV=refresh CONTENT=1;URL=http://open:o...@mynagios.com/nagios; This works perfectlyfor most browsers.

I'm trying to check for the size of an nfs share that is accessible from a windows host. The windows host is running NSClient++ but there are a number of problems here. First, the share isn't persistently mapped so at a minimum, I'd have to write a .bat warpper that first mapped it to a letter then ran the disk check.

Install, turned on snmp on the windows host. Mapped the drive to H and tried check_win_snmp_disk.pl $HOSTADDRESS$ $community 6 80 90 I did get information back. The % usage appears correct but the sizes are way off (Gig vs Terabyte). Can I trust the percentages from the above? Is the above script limited in size to Gigabytes?

Re: [Nagios-users] can nagios take some pro-active actions?
Ok, everyone agrees event handler can take action to fix a problem but bear in mind that this comes with caveats. Affectively, nagios event handler is treating a symptom; the disease goes merely on its way. If a service stops, WHY did it stop in the first place? Most good sysadmins would tackle the problem from the system end to insure that the service would never fail again. Furthermore, let's say a service failed for a reason, eg out of disk space. What good what it do to restart the service again? And if you build smarts into the event handler to look for and fix such a condition, is that the ONLY condition that could occur to stop this service? Having said all this, event handlers do have their place. We in fact use them to shut down hosts if the temperature gets too hot. You can imagine the testing we went through before rolling out something like this. On Thu, Sep 3, 2009 at 7:44 AM, Leonardo Carneirolscarne...@veltrac.com.br wrote: hello everyone.

not define them as part of the host group.

IDC-Ns2 , IDC-Ns2auth , SDC-Ns3 , SDC-Ns3auth
The CACHE_DNS host group should only contain CDC-Ns1, IDC-Ns2, and
SDC-Ns3. Why are the other hosts in there? I have tried renaming, I have
tried starting fresh with new config files, new retention data, new
object cache. Yet the hostgroup CACHE_DNS still contains hosts I did not
define to be there.
Any help is appreciated, clues, clue bats, links, (yes I looked at the

Probably not a coincidence that CDC-Ns1auth starts with CDC-Ns1. Sounds like it's using CDC-Ns1 as a prefix to match hostnames, rather than as an actual hostname. Looks like there's config setting in 3.0 called use_regexp_matching which might control that. Perhaps in your old config file that was somehow turned on. (Or perhaps not defined at all, and on is the default.) Who knows what other old settings you're inheriting too. It's probably best for you to scrap your old config, and start fresh with a new 3.0 config file, then adopt it to your needs (i.e., point it to whatever custom definitions/definition-files you've created). As I did, this is an all new install, everything is being re-done after a complete host and service audit of our network. There are no old configs in use.

keep getting some hosts added to a host group, even though I clearly did
not define them as part of the host group.

Everything looks fine, but when I start Nagios and look at View

Group Name Description Host Members
CACHE_DNS Caching DNS service CDC-Dnscache , CDC-Ns1 ,
CDC-Ns1auth ,
IDC-Ns2 , IDC-Ns2auth , SDC-Ns3 , SDC-Ns3auth
The CACHE_DNS host group should only contain CDC-Ns1, IDC-Ns2, and
SDC-Ns3. Why are the other hosts in there? I have tried renaming, I have
tried starting fresh with new config files, new retention data, new
object cache. Yet the hostgroup CACHE_DNS still contains hosts I did not
define to be there.
Any help is appreciated, clues, clue bats, links, (yes I looked at the
change log and searched for an answer, no luck).
Thanks,

Re: [Nagios-users] Simplified Nagios user interface for end users/help desk
Adam Forsyth wrote: I'm monitoring lots of different services on various hosts with Nagios. Many of these things are very useful for me to monitor as the sys admin, but when alerts occur occur with them, they do not represent downtime for our users, they represent problems I should fix proactively before they result in user noticeable downtime. For example, if Nagios notices a fan failure on one of my Procurve switches, I as the admin want to know about the problem, and probably want to replace the failing fan during the next scheduled maintenance time. The switch is still running just fine, however and there is no effect on service to users. Currently when I get such a notification, I'd acknowledge the problem, and it would stay in critical state until I've fixed the problem. What I'd like to create is a more end user targeted display of Nagios data. It would display OK or Alert status based only on whether the particular service is up or down from the user perspective, and wouldn't show any of the proactive nice for the sys admin to know about details. So in the case of the procurve switch, as long as the fan failure hasn't made the entire switch crash (we can still ping it) it would remain in an OK state. The only way I can think of to accomplish this would be to make a second installation of nagios. It would be a lot of duplicate configuration, but many of the services would be left out. I think that would create this second end user display as I'm imagining it, but it would come at the expense of having to maintain 2 sets of configuration files, and the server would have to do duplicate checking of lots of the services and hosts. Can anyone think of a better way to accomplish this that wouldn't need to involve duplication of checks? We have installed two of these for clients with Nagios in their networks. The best way we found, YMMV, was to use NagioSL. We wrote a flash app to poll NagioSL for devices to display on a pretty non-threatening map. We then wrote a new alert script that updates the flash map with any alerts/recoveries. It's rough around the edges but it works.

[Nagios-users] check_ping can't interpret output
I have the same version of Nagios installed on a dozen systems (not machines, full systems with several hundred machines each). Except for the specific list of machines, the configuration is identical between them. All are installed by yum from the Fedora 7 RPMs, version 2.10-3.fc7. All the plugins were installed the same way and are version 1.4.11-2.fc7. On one system only, check_host_alive (which calls check_ping) reports that all machines are down, while at the same time Nagios reports that most services on those machines are up. Running check_ping as root from the command line gets a successful response. Digging further, I have enabled user apache, which is the user httpd runs as, then tried the command as user apache. Here is the result. # /usr/lib/nagios/plugins/check_ping -H machine -w 3000.0,80% -c 5000.0,100% -p 1 PING OK - Packet loss = 0%, RTA = 0.16 ms # su - apache -c /usr/lib/nagios/plugins/check_ping -H machine -w 3000.0,80% -c 5000.0,100% -p 1 /bin/ping -n -U -w 10 -c 1 machine CRITICAL - Could not interpret output from ping command Some online references appear to suggest this could be caused by a LANG environment variable. I temporarily replaced the check_ping command with a wrapper script that saved the environment to a file before calling the actual command. There was no difference in LANG and the only other differences had to do with the name of the last machine tested. All systems report LANG=en_US.UTF-8. I have compared every configuration file for Nagios and Apache between systems and not found any unexpected discrepancy. I have verified the installation of all relevant packages (rpm -V). I can't find anything which explains the different behavior on the one system. Other suggestions are welcome. -- Dave Close - This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100url=/ ___ Nagios-users mailing list Nagios-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/nagios-users ::: Please include Nagios version, plugin version (-v) and OS when reporting any issue. ::: Messages without supporting info will risk being sent to /dev/null
[Nagios-users] nagios plugins on 32 bit

Re: [Nagios-users] Thoughts about a custom plugin
This can be done without NRPE. We have a cluster on a private net.
The head node is visible from nagios so I wrote a plugin that lives
on the head node (The dual homed machine, in your case). On the nagios
side, a plugin ssh'es to the head node, runs the script which talks to
hosts on the private net and returns the output/status.

There are alternate versions of NRPE that run on Windows, etc. if you

You should find that you can use normal plugins you already use
elsewhere with NRPE to do what you need.
I'm not certain this is intended for exactly the application I have. perhaps
it is, and I am misunderstanding it. let me clarify my application a bit

The Nagios host can get to the dual homed machine, and I can use all the
standard plugins to get status from it. What I want to do is get status from
the TARGETS.
Are you suggesting using NAPE running on the dual homed machines? And somehow
using this to query the targets? The web page you pointed out makes me
believe that NAPE is intended to allow me to execute checks on a reachable
machine, by using local scripts there, rather than having the NAGIOS machine
use the more traditional check_* plugins.
Am I confused?

Currently, we have a perl script search for just one or two specific lines and pass the results to send_nsca. It's crude and doesn't cover all instances.

It depends on whether notes is willing to speak to a client with a protocol that fetchmail knows. (POP worked for me, not sure what notes likes.) Added advantages over procmail - definitely simpler, probably consumes fewer resources, possibly easier to keep secure (especially due to the complexity issue). I am unfamiliar with notes, doesn't it have some sort of native pre-processing available? Dave On Jan 4, 2008 6:31 AM, [EMAIL PROTECTED] wrote: It's the procmail part that will be the political hot potato. Thou Shalt Have No Other Email Platform Before Me is the edict from on high, regarding notes. Not withstanding that the nagios server has to have a mailing agent of some sort to work of course.

Re: [Nagios-users] restricting unknown user
arpwatch does something like that, keeps an eye on what mac addresses are active using what IP on the local subnet, sends an alert when a new mac address appearrs or some change occurs in the pairs of active MAC/IP pairs. Currently there is no integration between arpwatch and nagios. arpwatch sends email alerts, maybe outputs to the log or console? I don't think it is a good fit, since nagios assumes that all the hosts it cares about are pre-defined in its config file. There might be a web front end available for arpwatch I am unfamiliar with, if so that sounds more like what you want.

[Nagios-users] putting limits on check_by_ssh
I've been RTFMing SSH. For background authentication like nagios uses, the book I'm reading recommends using the user's ssh config file to limit using passwordless keys to just do one task each. So if you want nagios to be able to do 3 kinds of checks without a password, you put 3 keys in nagios .ssh/authorized_keys file with command= stuff for each. Then no matter what nagios thinks it is asking for (parameter of check_by_ssh) it gets whatever is configured for that key. I'm just wondering if anyone has taken this approach. It seems a bit complicated, spreading some of the nagios config info around to each monitored system, but it sort of appeals to me. Then you know that even if someone manages to get your key, all they can do is check_disk or something else boring. Am I missing something? In addition to limiting key authentication to doing specific tasks, I also put an '*' in the nagios user's password field in /etc/passwd, which prevents them from logging in by password.

Thanks to the two Toms for their helpful responses. On Nov 16, 2007 8:26 AM, Thomas Guyot-Sionnest [EMAIL PROTECTED] wrote: While I use command-restricted keys for all passwordless auth (usually cronjobs), this is the reason why I never looked into check_by_ssh and use NRPE instead. NRPE makes me a bit nervous because I suppose (without any data to back it up) that relatively few people use it (at least compared to ssh). What criteria did you use in making the evaluation of check_by_ssh vs. NRPE? SSH is tempting because I don't have to install and configure much new stuff or learn much new stuff, or at least what I learn has broad applications. And though the configuration may be a bit long-winded, it seems pretty clear. And I *think* I can nail it down pretty well, so that even if my private keys on the nagios server got compormised, nothing much bad could happen to the other hosts. You can also set the shell to /bin/false and set a non existent home directory (ex. /nonexistent). Doesn't the nagios user need a shell and a home dir to run the daemon? Maybe I was just thinking that it needed a home dir to put the ssh keys in, but they can be located anywhere. Slowly understanding blooms.

Re: [Nagios-users] putting limits on check_by_ssh
My problems with NRPE are: 1) I know nothing about it. 2) I think it requires me to open up another port on my machine. My problems with SSH are: 1) configuration is a bit tedious My positives for SSH are: 1) It is very well known and respected 2) Lots of people use it for lots of things, not just nagios My positives for NRPE are; 1) I was hoping you guys would tell me what helped you decide to go with NRPE. I just don't know much about it. Since I feel fairly confident that I could seal up an SSH configuration, but NRPE is an unknown factor for me, it is very tempting to stick with SSH.

Re: [Nagios-users] Can Nagios implement with Expect to automate tasks when issues arise?
Event handlers can take care of any common task but you need to be careful with them. Why is a task required to be done so frequently? Shouldn't we take care of the cause rather than the symptom? Also, scripts that fix known problems can be very dangerous if they inadvertantly run at times when a service/host looks critical but perhaps critical wasn't well enough defined, particularly if you're not using parent dependancies. So if you do go this root (pun intended), add in a LOT of checks to the expect script. On Nov 14, 2007 11:27 AM, Patrick M.

[Nagios-users] nagiosgraph restart, aggregate.cgi
I had a linux-based nagios 2.9 install with nagiosgraph 0.8. The server recently shutdown and upon startup, while nagios ran fine and nagiosgraph.log and perdata.log both show the correct type of activity, new graphs simply weren't generated after startup. The classic: Illegal attempt to update message goes into the log. I took this to be just a warning that one of the epoch values is incorrect. I base this assumption on the fact that higher level debug shows RRD inserts. I tried running insert.pl manually, moving the RRDs aside to make new ones but still couldn't get the graphs generated so I backed up my setup and upgraded to nagiosgraph 0.9. Now I am generating graphs however nagiosgraph-0.9 has an update.pl which moves the RRDs into hostname subdirectories. I installed aggregate.cgi with the previous version to create a single webpage with all the graphs and this no longer works due to the RRD format or location. Does anyone have a patch or newer version of aggregate.cgi (http://www.nebrwesleyan.edu/people/stpierre/aggregate.cgi) Also, I notice that the perfdata.log file seems to get rolled on its own every few minutes and running nagiosgraph with warning-level debugs produces a warning perfdata not recognized. I presume these two events are related. Thanks - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems? Stop.

Unfortunately, not all services I wish to define via wildcard

a combination of hostgroups and hosts eg
define service {
hostgroup unix, ultrix, sco
service_description
}
define service {
host_name host1, host2, host3, host4
...
}
Anyone find a way around this?

Re: [Nagios-users] Just using SNMP
You can do the NSclient installs remotely by staging it on a common share, have a .cmd file something like this: mkdir c:\nsclient @if %ERRORLEVEL%==1 goto :EXIT copy C:\\temp\nsclient\Win_2k_XP_Bin\* c:\nsclient @if %ERRORLEVEL%==1 echo error occurred while copying files c:\nsclient\pNSClient.exe /install @if %ERRORLEVEL%==1 echo error running pNSClient net start nsclient @if %ERRORLEVEL%==1 echo error occured while starting nsclient service The above can be remotely run thru a variety of mechanisms, even submitting a remote scheduler job to run once. Then just write a script to install on all your servers once it's been tested.

[Nagios-users] nagfs
Hiya. nagfs is an event broker module, which implements a filesystem interface to the current status of a running Nagios daemon. This means in a nutshell that you can query the status of a given service or set of services using everyday shell tools like find and grep. Each host is represented as a directory in the filesystem. Each host directory contains a file for each service nagios is monitoring on that host. Each file contains a single number representing the state of that service. For example, once nagfs is running, you can list all the services currently in a critical state by typing: grep -rl 2 /usr/share/nagios/status/local The numbers are what you'd expect ( 0:OK, 1:Warning, 2:Critical, 3,Unknown). If the service is in a soft state a servicename.soft file is created with the soft state status number. Each host directory also contains a HOST file which contains the current status of the host itself. As a second example, you could get a list of all the services Nagios is checking with: find /usr/share/nagios/status/local -type f This is a handy thing, and much easier than scraping html for the same info. nagfs registers for SERVICE_STATUS_DATA and HOST_STATUS_DATA updates from the Nagios server, which means that the nagfs filesystem is immediately brought up to date upon Nagios startup, and is always perfectly in sync with Nagios's memory state. It's released under the BSD license. The tarball is available on nagios exchange, and my blog http://www.skeptech.org Nagfs was originally the brainchild of Jeremy Blosser, who implemented it as a collection of shell scripts called via global event handlers. I found it so useful, and became so attached to it that I eventually forgot it wasn't actually part of the core Nagios package. I later re-implemented it as an event broker module as an object lesson for the addison wesley nagios book I authored, and refined it as part of a larger nagios clustering project called nagimesh, which is not yet complete. However, I find nagfs so indispensable that I decided to release the source as a stand-alone NEB module, in the hope that you may too someday forget the time you've already spent without it. Check INSTALL in the tarball for installation instructions. It is assumed that you have a working Nagios implementation which has been compiled with the --enable-event-broker configure switch. I have several Nagios servers running versions of Nagios from 2.0alpha1 to 2.8, and nagfs works with all of them, so it ought to work for you if you haven't ventured into 3.0 territory yet. I haven't taken a look at the 3.0 event broker code yet, so for all I know it could work (if you try it and it works for you let me know). Have fun! -dave josephsen. - Take Surveys. Earn Cash.

But it would be quite useful to have hostgroups based on operating systems. Anyone have a way to accomplish this allow multiple views? TIA - Take Surveys. Earn Cash.

[Nagios-users] plugins with rsh
We have a legacy setup with tru64 hosts that are currently configured for rsh, not ssh. I've installed the latest and greatest nagios on a relatively recent fedora host and have used plugins with ssh in the past. The problem is that rsh doesn't return status codes properly. Rather, it returns only the status code of rsh itself, not the command. A search implies you just need to echo $? with rsh. rsh linux to linux, I get this: linux1 rsh linux1 'date ; echo $?' Wed Jan 3 15:15:07 EST 2007 and trying to generate an error: linux1 rsh linux1 'bogus ; echo $?' bogus; Command not found. 1 So that looks ok but first problem is when I put into nagios commands define rsh $HOSTADDRESS$ 'mycommand; echo $?' The web page show (No output!) Is it possible it swallows the quotes? Further, rsh behaves differently on tru64: linux1 rsh tru64-host 'date;echo $?' Variable syntax. Any ideas for these problems?

[Nagios-users] host details time vs service details time
We have an interesting problem that might be quite simple. Listing service-details shows all hosts and their services and last-check time correctly. Listing Host-details shows older last-check times (perhaps up to a month). If the host goes down, the last Check date is correct. If it comes back, the date is correct and seems to keep that date. In other words, the last-checked field on the hosts-detail page retains only a state-change. I'm using active and passive test on nagios 2.3. Here's the output from nagios -s. Note that the Total sheduled hosts is 0. Thanks HOST SCHEDULING INFORMATION --- Total hosts: 696 Total scheduled hosts: 0 Host inter-check delay method: SMART Average host check interval: 0.00 sec Host inter-check delay: 0.00 sec Max host check spread: 10 min First scheduled check: N/A Last scheduled check:N/A SERVICE SCHEDULING INFORMATION --- Total services: 2120 Total scheduled services: 2120 Service inter-check delay method: SMART Average service check interval: 300.00 sec Inter-check delay: 0.14 sec Interleave factor method: SMART Average services per host: 3.05 Service interleave factor: 4 Max service check spread: 8 min irst scheduled check: Mon Aug 14 11:25:06 2006 Last scheduled check: Mon Aug 14 11:30:05 2006 CHECK PROCESSING INFORMATION Service check reaper interval: 10 sec Max concurrent service checks: Unlimited PERFORMANCE SUGGESTIONS --- I have no suggestions - things look okay. =-=-=-=-=-=-=-=-=-=- generated by /dev/dave -=-=-=-=-=-=-=-=-=-=-=-= David SternUniversity of Maryland Institute for Advanced Computer Studies - Using Tomcat but need to do more?

Re: [Nagios-users] how to string commands?
On Fri, 28 Jul 2006, Thomas Slutyer wrote: I am defining a template for my linux machines. I'd like the check_command for that template to have it check ping, local drive, pop, httpd, etc How can I string them together? Would something like this work: check_command check-host-alive; check-pop; etc.. or do I need to use commas or is this completely illegal? It won't work. Each check commad can only have one result. Whereas Nagios' syntax will not allow for such trickery, you -could- however make a composite check script yourself. Just create a shell script that calls all of the checks you want to perform and let the script decide on the exit code and alarm message, based on the output of the other checks. This way I've create real service checks for our SMTP environment for example. Why? Because a mail environment is more than just a running SMTP daemon. My script checks: * Are the main SMTP VIPs (Virtual IPs) available in DNS? * Is the load balancer running the VIP properly? * How many SMTP servers out of our complete pool are up and available for SMTP? * Are we able to connect to send a message. That way you can safely say that service X works properly :) Great idea for single services such as smtp but not so good for overall system health as it's difficult to quantify. For smtp, you might right a script to - see that smtp is running - see that the spool area has free space - see that system load is reasonable (que load average for sendmail might otherwise start refusing new messages) and finally if all is well, send back a good status, if not, decide on status (warning or critical) and output appropriate message. But even here, the problem is that the different things you're checking are not necessarily reliant on each other so several of the above could have problems and if so, what should the overall status and output message be. So by extension, writing a single script to test many unrelated items defining the overall health of a host can result in confusing output. =-=-=-=-=-=-=-=-=-=- generated by /dev/dave -=-=-=-=-=-=-=-=-=-=-=-= David SternUniversity of Maryland Institute for Advanced Computer Studies - Take Surveys.

[Nagios-users] nagios speed to refresh
I have a nagios 2.3.1 install that is acting laggy. Updates can be as old as a half hour for the ~2200 services I monitor. I'm currently using active and passive checks, generally with 10 minute check intervals altho some have intervals of 30 minutes so as not to kill these hosts. I intend to reduce the check interval and am considering changing inter_check_delay_method from smart to something else. By default, inter_check_delay_method=s is commented out of nagios.cfg and just uncommenting makes it complain when I run nagios -v saying UNKNOWN VARIABLE so I can't even change it to n or d or some small number of seconds. I'm guessing the config I have may need to be converted(?) I'm looking to get information no older than 10 minute (assuming the nagios server can handle it) Has anyone had any experience with this? Here are some values of interest: command_check_interval=-1 freshness_check_interval=60 status_update_interval=30 % nagios -s nagios.cfg ...

[Nagios-users] compiling nagios-2.3.1 on solaris
I've downloaded nagios 2-3.1 for a number of architectures after the
cgi buffer overflow exploit described in
http://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2006-2162
The compile for our server (Rhel3) went fine. But To keep things clean, I
want to replace the structure on other OS's including Solaris8. Here's what
I'm getting. The line indicated appears to be new code to check for the
buffer overflow. Has anyone had any probs building this on solaris?

Here's the line numbers for getcgi.c
173 /* suspicious content length */
174 if((content_length0) || (content_length=INT_MAX-1)){
175 printf(getcgivars(): Suspicious Content-Length was
sent with the POST request.\n);
176 exit(1);
177 }
Fortunately, we only use the plugins on Solaris but I'd like to get the
whole structure built anyhow.

[Nagios-users] Status map circular markup background bug
I have noticed the following bug and am not sure where to report it. We have a number of hosts with multiple parent links, and this seems to confuse the circular markup status map. It draws the green (or pink) background colors in BOTH places where the relevent nodes could be, even though the nodes are only drawn in one of the places. Also sometimes it seems to crowd things together a little too much (icons and text overlapping other icons and text), even when there is room for it to spread things out more. I suspect this may also be related; when there are two parent links, and as a result it could draw the icons in the 3rd outer circle in one position, or in the 7th outer circle in the other position, it seems to draw the icons in the 3rd outer circle, but using the spacing for the 7th outer circle, or vs versa. I couldn't find any other reports of these particular status map problems. I can provide an example image of the status map showing these problems if necessary and someone tells me where to put/email it. --- This SF.Net email is sponsored by xPML, a groundbreaking scripting language that extends applications into web and mobile media.

Did you check the timeperiods.cfg file as you are using workhours

2006/2/23, Dave Stern [EMAIL PROTECTED]:
I didn't include timeperiods.cfg because this was the generic one.
We're using workhours and 24x7 for all hosts.
Basically, notification_period is 24x7 for all,
{service|host_notification_period} is either 24x7 or workhours.
I presume it's not a problem if a host is set to notification_period=work
in contacts but 24x7 in hosts.cfg and services.cfg

[Nagios-users] nagios not notifying by email
We have two iterations at our site, one running the old netsaint (which
works flawlessly) and one running nagios 1.2 on RHEL E3-AS. The latter
rebuilds its config files each night based on various site-specific
files detailing what hosts we have, what to monitor on them etc.
The Linux version is not notifying when hosts/services go down. I suspect
this is nothing more than the notify-by-email command.
On netsaint, it's
command[notify-by-email]=/usr/bin/printf '%s\n%s\n%s\n%s' '* NetSaint 0.0.7
* $SERVICESTATE$ alert/notification' 'Host: $HOSTNAME$ Address:
$HOSTADDRESS$', 'Additional Info: $OUTPUT$' | /usr/bin/mailx -s 'Service alert:
$HOSTNAME$ is $SERVICESTATE$ **, $SERVICEDESC$' $CONTACTEMAIL$
and on linux its
# 'notify-by-email' command definition
define command{
command_namenotify-by-email
command_line/usr/bin/printf %b * Nagios *\n\nNotificati
on Type: $NOTIFICATIONTYPE$\n\nService: $SERVICEDESC$\nHost: $HOSTALIAS$\nAddre

}
Does anyone know what the command should look like and how to test the above?

[Nagios-users] service dependancies
I've been running nagios for a while and love it. One of the plugins I
wrote ssh'es to various hosts and checks automounts by trying to read
a file on each of our critical automount hosts.
If the host doesn't respond to ssh, then the webpage obviously shows
that and the various automounts as down. It would be nice if you didn't
have to decode the webpage in that way ie if it only reported ssh as
down due to the dependancy. I was hoping that servicedependency could
do this something like
define servicedependency{
host_name either specific hostnames or wildcard
dependent_host_name
dependent_service_description ssh
service_description nfs*
}
Can this be done? using the above format?
TIA
