Re: [Nagios-users] Issues with NEB modules breaking after restart
divTo answer my own question... I'm pretty sure two nagios instances were spawned at once. The nagios init script that comes with nagios-core is the best at handling this situation./div -- This SF.net email is sponsored by Windows: Build for Windows Store. http://p.sf.net/sfu/windows-dev2dev ___ 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] Issues with NEB modules breaking after restart
I recently just upgraded to the latest 3.5.0 release of nagios-core and just added livestatus into my environment. We are trying to replace NDO but currently have the two running at the same time along with NCPD for perfdata which as far as I know there shouldn't be an issues . The first issue I had was where Nagios would segfault every night during it's routine log rotation so I applied the 0007-fix_downtime_struct.dif patch which seems to have fixed that issue. I experienced a new issue this morning where when restarting Nagios none of the NEB modules uninitialized properly. Nagios was able to start and initialized all of the NEB modules but a few seconds later Nagios uninitialized them again. This isn't like anything I've seen before and none of the NEB modules worked after this occurred. Here is what the logs looked like. [Thu Jun 13 09:30:29 2013] Caught SIGTERM, shutting down...

Re: [Nagios-users] High Availabilty with Nagios
I did a talk at last years conference that touches on HA Nagios setup which uses DRBD and pacemaker. There were also talks about mod_gearman and Merlin that might also be helpful. The slides (and maybe video?) are available on nagios.org.

[Nagios-users] solutions for off-server PNP4Nagios perfdata processing?
There are two options that I know of. The first is there is an undocumented NEB module that comes with PNP4Nagios located in src/module called modpnpsender.c that looks like it send data to a remote server to get processed. If anything you can use it as a starting point. This blog article talks about using it and if you look at the source you can find the original author and possibly more details: -- Don't let slow site performance ruin your business.
