[Nagios-users] nagios future?
Hi As somebody already heard about icinga http://www.icinga.org? Now, we planned to install nagios on a productiv server and nagios is very fine and we're happy with it.

[Nagios-users] Recovery notifications after escalations
Hi,
We have a a situation here where we would like notify the on-call
group after 60 minutes and the support group after 240 minutes. If
services go down and then recover, everyone who has received a
notification of a host problem should also receive the recovery
notification. See the configuration below.
Now, our problem is that when the second escalation has been activated
and the support group has received the notification, only the support
group will receive the recovery notification - the on-call group will
never see the recovery notification.
We do not want to send out multiple notifications to the on-call group
four the same issue since they then would be spammed by Nagios
unnecessarily.
define host{
namegeneric-host
...
contactsroot ; This will be stored in
a local mailbox that no one sees
notification_interval 60
notification_optionsd,u,r
register0
}
# First escalation for on call group (notification after 60 minutes)
define hostescalation{
host_name *
first_notification 2
last_notification 2
notification_interval 180
contact_groups on-call
}
# Second escalation for support group (notification after 240 minutes)
# Problem: when this escalation has been activated, on-call does not
receive recovery notifications anymore
# (we do not want to send multiple notifications about the same
problem to on-call)
define hostescalation{
host_name *
first_notification 3
last_notification 3
notification_interval 0
contact_groups support
}
Is it possible to achieve what we want using escalations?
Best regards,
Ulf Karlsson

Re: [Nagios-users] nagios -- ndo2db -- centreon
Thanks for all the help!!! Was able to get everything working.

I spoke a little bit too soon. Although a couple of the hosts showed up,
that's all I can get to work. I've added more, and the nagios configs
get updated, yet nagios doesn't show any changes. So I'm missing
something on the nagios/configuration side.
If I take a bracket out of one of the configs, then nagios won't
restart, so I know it's reading these cfg files. In the files
below, srv-xen02.mydomain.com and srv-xen03.mydomain.com are working,
but none of the others are.
If I remove one of these hosts (using centreon frontend) it removes it
from the configs, nagios is restarted, but nagios is not updated. It
still shows the same two hosts.
Anyone know what I might be missing? Here are some of my configs. The
contacts listed in these configs all exist.

But maybe I can put some ideas in your head. My first thought is that if they want the recovery notification maybe they would not mind the extra one either. The extra one actually tells them that the issue was escalated and might be useful information. If they don't want the issue to escalate, they should acknowledge it (sticky). In order do fix it to work like you asks I have two suggestions. None of them is good. If you do not have that many contacts, create an additional one for each member in the on-call with only recovery-alerts and put them in a group, e.g. on-call-recovery and escalate to that one. They will now get the recovery notification. An other alternative is to modify your notification-command to take notice of the macros $SERVICENOTIFICATIONNUMBER$ and maybe $HOSTNOTIFICATIONNUMBER$ and build the logic you wish. Make sure to do it right so you don't miss important notifications. But, as I said, I don't like any of the ideas.

Yep that is true but to say Hey it's like Nagios but not the same all names had to be removed/changed. But concerning merging patches it shouldn't be that big problem. Current Nagios patches have been pulled over and merged into actual Icinga source. So backwards it should work then too. Very realistic.

Given how simple the Merlin schema is, I have no doubt that we'll provide patches to other projects to achieve the same thing. Yeah i like that move because everyone is holding back on the DB schema of the NDO which is far too normalized and doesn't scale. And my biggest concern right now, Oracle limits table and column names to max 30 characters (varchar2(30)). Maybe you'll keep an eye on that while testing your schema. It's been planned, implemented, tested and available since 2009-03-17. Additional bugfixes happened later, but libdbi has been in use in Merlin almost three months now. Ok good to hear that - some query normalizations and other database specific stuff will pop up for sure.

Re: [Nagios-users] Recovery notifications after escalations
Marcus Rejås wrote: On 06/09 12:06, Ulf Karlsson wrote: Hi, We have a a situation here where we would like notify the on-call group after 60 minutes and the support group after 240 minutes. If services go down and then recover, everyone who has received a notification of a host problem should also receive the recovery notification. See the configuration below. Now, our problem is that when the second escalation has been activated and the support group has received the notification, only the support group will receive the recovery notification - the on-call group will never see the recovery notification. We do not want to send out multiple notifications to the on-call group four the same issue since they then would be spammed by Nagios unnecessarily. I don't (at least not yet) have a good answer. But maybe I can put some ideas in your head. My first thought is that if they want the recovery notification maybe they would not mind the extra one either. The extra one actually tells them that the issue was escalated and might be useful information. If they don't want the issue to escalate, they should acknowledge it (sticky). In order do fix it to work like you asks I have two suggestions. None of them is good. If you do not have that many contacts, create an additional one for each member in the on-call with only recovery-alerts and put them in a group, e.g. on-call-recovery and escalate to that one. They will now get the recovery notification. I don't think they will. There are checks to make sure recovery notifications are only sent to contacts who have received the previous problem notification. An other alternative is to modify your notification-command to take notice of the macros $SERVICENOTIFICATIONNUMBER$ and maybe $HOSTNOTIFICATIONNUMBER$ and build the logic you wish. Make sure to do it right so you don't miss important notifications. But, as I said, I don't like any of the ideas. There are very smart people on this list and someone will probably give you some more advice. Sending a patch to make sure each problem object in the Nagios core contains a concatenated list of normal and escalated contacts would be favourite, since that would mean everyone who received the problem notification will also get the recovery notification. This would best be implemented by building a linked list with only unique elements to operate on. The list should probably contain a marker to mention which contacts were added from the escalation, so the original contacts do not get notified if they don't want to get the escalated notifications. -- 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. -- Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects ___ 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

Ethan wants some time to manage patches and stuff like he's used to without having to learn another tool. I'm sure he'll curse himself for not switching sooner when he learns the benefits of git, but at least we're getting there. Well some common aliases from cvs for git will help too ;-) I've been looking onto git for about 3 weeks and I like to use this cheatsheet a lot: http://ktown.kde.org/~zrusin/git/git-cheat-sheet-medium.png Ugh. I absolutely hate that, because it just tells you do this, do that but doesn't explain *why*. It never mentions why the index is there, or how you can use it when you run into stuff that's actually *hard*, such as an 8-way merge that suddenly went wahoonie-shaped. But to each his own, I guess. One of the annoying things about the icinga-fork though is that they've mainly done a lot of renaming and not so much actual patching. This will ofcourse merge cleanly but in an unsatisfactory way for Nagios. Messy, but certainly possible to work around. Yep that is true but to say Hey it's like Nagios but not the same all names had to be removed/changed. But concerning merging patches it shouldn't be that big problem. Current Nagios patches have been pulled over and merged into actual Icinga source. So backwards it should work then too. It has? I'll have to take a look at that, I think. The hard part will be to separate the cruft from the code, so that only the real changes appear in a diff. Some simple sed magic will probably do the trick though. Very realistic. We're already using it for development to that purpose, and it's working just fine. One problem with NDOUtils is that the database schema makes it impossible to write stuff for it that scale linearly. That's totally unacceptable for us, so we had to come up with something new. Fortunately, Lars Hjemli of the NagVis project has been very friendly and cooperative in helping us add support for the Merlin database schema in NagVis. Given how simple the Merlin schema is, I have no doubt that we'll provide patches to other projects to achieve the same thing. Yeah i like that move because everyone is holding back on the DB schema of the NDO which is far too normalized and doesn't scale. And my biggest concern right now, Oracle limits table and column names to max 30 characters (varchar2(30)). Maybe you'll keep an eye on that while testing your schema. I haven't actually thought about it. A quick glance reveals that the serviceescalation_contactgroup junction table is the one with the longest name, weighing in at 31 characters. That can be fixed quite easily though, since junction table names are determined by a function which can easily special-case this particular one. It's been planned, implemented, tested and available since 2009-03-17. Additional bugfixes happened later, but libdbi has been in use in Merlin almost three months now. Ok good to hear that - some query normalizations and other database specific stuff will pop up for sure.

When everything works out I hope to push source for libdbi Oracle soon to Icinga IDOUtils.

Re: [Nagios-users] nagios monitoring for hack
I'd look into the various hardening and monitoring tools available (Bastille, Tripwire, chroot, etc). There's different tools for different purposes, obviously. We chroot all our BIND and Apache stuff. Bastille is great for hardening the environment. Tripwire monitors for changes to key files. Each program has its own logging mechanisms. So once you have your tool in place, you can use Nagios to watch the log file(s) and generate alerts based on keywords (ALERT, WARN, CRIT, etc). You can also dump your logs to an alternate server and have Nagios watch them from there, but in the case of DDoS attack, your bandwidth may be affected for remote syslog and/or Nagios network checks.

[Nagios-users] DNS down and false alerts...
I've observed an interesting issue with Nagios. Our environment is a mix of UNIX, Linux, Apple, and Windows. The core of the network is Active Directory including two AD servers that are both our primary, internal DNS servers. All non-Windows systems have a resolv.conf that looks like: *nameserver 10.1.1.13 nameserver 10.1.1.14 domain int.our.domain search int.our.domain* About half of the servers have the nameserver entries inverted (ie: .14 first, .13 second). The issue is that anytime one of the nameservers is rebooted (at least once a month if staying current on patches thanks to Black Tuesdays), whichever hosts have that nameserver listed first in its resolv.conf start throwing the following errors: *CRITICAL - Plugin timed out while executing system call.* This occurs for multiple tests for each host. Obviously, there's a name resolution correlation here. If the nameserver with .13 is rebooted, all hosts (about half of them) that list this IP first in their resolve.conf then timeout for multiple tests. If the .14 server is rebooted, all the other hosts timeout. Interestingly, none of the Windows clients issue errors... only UNIX, Linux, and Mac's... only those with an /etc/resolv.conf. The end result is a host of false positives, but more importantly it looks bad on availability reports and causes phones/pagers to go ballistic with unneeded emails. I'm trying to find a solution and I can't find one that I like: Solution 1) is to cluster the DNS servers. We have lots of clusters here. This isn't good, though, as you don't normally cluster DNS servers... they're meant to be redundant for a reason... one fails and it uses the next one. Solution 2) is to setup a service/host dependency. My thought would be either a host dependency that says if either .13 or .14 are down, then don't alert for any other host that uses them. Or a service to host dependency... if the DNS service is down, then don't alert on any of these dependent hosts. Honestly, I'm not sure if you can mix host and service dependencies like this... plus... if the DNS server is actually down, then the DNS service is down, so better to use a host dependency. The problem is that now we're not alerting on any dependent hosts which themselves could have a legitimate issue we want to know about. Plus, what happens if the DNS server actually dies and take a few hours/days to rebuild/restore? At this point, the dependent hosts aren't watched for a very long time. Solution 3) is to setup a UNIX/Linux DNS server that slaves all zones from the AD servers and have all UNIX/Linux/Apple clients query from this server. This would work except that A) I need two of them to keep redundancy and B) I've now added an extra layer of complication to resolve an application (Nagios)... not exactly good practice. Solution 4) is to set the timeout value of a host querying a DNS server. Perhaps adjust the client to timeout on the first listed nameserver after only 10 seconds, then try the next one? Since most Nagios tests have a minimum timeout value of 30 seconds, if the first DNS query timed out after 10 seconds, it would go to the next one with, hopefully, enough time to respond. The downside is having to adjust every single server. Has anyone else seen this? Anyone else using Windows AD servers to provide DNS for *nix servers? -- A.

[Nagios-users] Synchronizing turning off notifications.
We have two Nagios servers with one acting as a fallback. We run a sync program every time there is an update. This sync copies the config files from mon1 to mon2, stops and restarts the backup. Works well, but the problem we're having is that it is not syncing when we turn notification off on mon1. If it falls back to mon2 it will page for that device. Does anyone know where Nagios stores the notification=off option when it is changed via the web interface? I suspect we're missing the copy of that file.

Re: [Nagios-users] DNS down and false alerts...
Really the best choice is to using caching DNS on the Nagios server. I'd recommend dnsmasq, it just does caching locally without needing to do big zone transfers. It has low overhead and simple configuration as a result. Enjoy. On Tue, Jun 09, 2009 at 11:19:20AM -0400, Andrew Davis wrote: I've observed an interesting issue with Nagios.

My reading of the issue, and I believe that I've seen it in the past as well, is that the problem isn't with DNS resolution on the nagios box but DNS resolution happening on the target boxes. Installing a caching nameserver on the nagios box isn't going to help any. The target system is trying to do a DNS lookup on the connecting host (nagios). The OP isn't specific on how he's checking these boxes so it could be xinetd, nrpe, whatever... The default timeout for DNS server failure detection in the resolver libraries is too long so the plugin times out.

Re: [Nagios-users] DNS down and false alerts...
I don't know if I'm misreading the OP, but if the plugins start timing out on only the boxes whose primary DNS is being rebooted, would adding a caching DNS server to the Nagios box really make a difference? I think the root cause to these timeouts is that the Nagios plugin timeout is happening before the connection to the primary DNS on the target machine has a chance to time out and then connect to the secondary DNS. The correct course of action to resolve this would be to either make sure that the DNS connection on the target machines fail quicker, or that Nagios/the plugin waits longer for a result from the check. The DNS failover is working as designed here but you're not giving it enough time to kick in.

The hard part will be to separate the cruft from the code, so that only the real changes appear in a diff. Some simple sed magic will probably do the trick though. Would be bad if it hasn't - as long as both projects are mainly compatible they can profit from each other. Right. I'll have to revisit it and see what's new. GIT is really nice for that I know. I helped write it after all :p but you should ask Hendrik instead how to deal with that :-) I think I'll find a way. Thanks for the tip though. I haven't actually thought about it. A quick glance reveals that the serviceescalation_contactgroup junction table is the one with the longest name, weighing in at 31 characters. That can be fixed quite easily though, since junction table names are determined by a function which can easily special-case this particular one. Mh thanks for the tip I need to think about that in more deep. Well, it'll be ambiguous even if one char is stripped from it, so just cutting the name at 30 chars might be worthwhile if we're on oracle. Since libdbi provides a database-agnostic api (it would be quite useless if it didn't), a simple thing such as loading the correct driver should suffice to make it work with Merlin as well. Which driver to use can be specified in the Merlin configuration file. However, there's currently no oracle driver for Kohana that I'm aware of, and that means Ninja won't be able to benefit from an Oracle database even if Merlin can write to it. The thing which I am missing in libdbi-implementation is parameter binding which really is a performance tweak with lots of queries with different values. Another headache but maybe I'll hack that and send a patch to the developers. Mostly it is important for Oracle meanwhile. About Kohana - had a short look into the Database drivers. Oracle support won't be that big problem to implement but that won't be me. Hopefully it will be done because then Ninja and Merlin combined to Nagios would be an option alternatively to Icinga with optimized IDO for Oracle (which is my main task right now). Well, unless I'm mistaken IDO will have the same database layout as NDO, so it will still suck for performance, and writing good queries for it will still be a major headache. When the storage model of the algorithm algorithm is broken, tweaking it doesn't really help. Only a rewrite can save you then. It would be neat to see Merlin adapted to Oracle though, so if you're interested in working on that we'd sure help as much as we can. -- 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. -- Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects ___ 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

It looks to me that following line in include/common.h causes the issue #define MAX_DESCRIPTION_LENGTH128 I assume that I need to recompile nsca ( for the server ) and send_nsca ( for the client where I need to use a service description longer then 128).

Re: [Nagios-users] DNS down and false alerts...
Hey... I'm the OP. We're using a mix of client tools. For Windows systems (which aren't affected by this) we use nsclient++. For our Linux servers, NRPE... for UNIX (Solaris) and OS X we're using check_by_ssh. Both the NRPE and check_by_ssh clients are affected by this. I'm willing to give the caching nameserver on the server a try, but as others have noted, I don't think it will make a difference as its the local test on the client that's failing to resolv. I surely cannot do a caching nameserver setup on all clients... A.

There are checks to make sure recovery notifications are only sent to contacts who have received the previous problem notification. You are absolutely right (as always, however this time I took the time to test and prove myself wrong...). I am, and was, aware of the checks you are referring to and they really do make sense in most places e.g. leaving and entering timeperiods. But in this context they are confusing.

This is not something I would see fixed but it might be good to point this out on host- and service_notification_options in the manual. Sending a patch to make sure each problem object in the Nagios core contains a concatenated list of normal and escalated contacts would be favourite, since that would mean everyone who received the problem notification will also get the recovery notification. This would best be implemented by building a linked list with only unique elements to operate on.

I don't know what they're named for english platforms (or any other for that matter), but you should be able to view them with that thing you can pop up when pressing ctrl-alt-del (task manager or whatever it's called). -- 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. -- Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects ___ 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 -- Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects ___ 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 -- Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects ___ 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

The server has always been Solaris (sparc or x86), use inetd/xinetd/deamon mode again zero error The one 'problem' i have seen people complain about is ssl and nrpe, read the manual and it should pretty clear what todo, 99.9% is almost the use not having doing some RTFM thingy :) The other one is tcp-wrapper and nrpe, nrpe has a access control buildt-in so I never understood one would need to use tcp-wrapper :) -ls From: N Patil To: Eric Pearce Cc: Nagios Users Mailinglist Sent: Thursday, May 28, 2009 9:13 PM Subject: Re: [Nagios-users] Error while configuring NRPE on solaris Thanks Eric, I have followed the same article but it dint help.
