Hi, I'm running nagios 4.0.8 and I noticed that the Nagios process has unexpectedly crash recently. I have livestatus and thruk. I'm not sure what's causing it to crash and was wondering where I should look to isolate the issue.

I have a feeling it may be the thruk BPI addon because that's the only thing I enabled recently. Below is a snippet of the error.

Code: Select all

[1411400822] Warning:  Passive check result was received for service 'Virtual Infrastructure' on host 'Virtual Infrastructure', but the host could not be found!
[1411400822] Error: External command failed -> PROCESS_SERVICE_CHECK_RESULT;Virtual Infrastructure;Virtual Infrastructure;0;OK - everything is fine

When I restart the nagios process, I get the following error indicating it could not find the process, which indicate that it indeed crashed.

Code: Select all

root@RWCNAGIOS:~# service nagios restart
Running configuration check...
Stopping nagios:/etc/init.d/nagios: 140: kill: No such process

 done.
Starting nagios: done.

Edit nagios.cfg and up your logging. Also look at /var/log/messages to see if anything is posted there.

What are the permission on the command pipe?

Code: Select all

ls -la /usr/local/nagios/var/rw/nagios.cmd

They should be similar to:

Code: Select all

prw-rw---- 1 nagios nagcmd 0 Sep 22 15:29 /usr/local/nagios/var/rw/nagios.cmd

Did you notice any useful errors/warning in the logs mentioned by eloyd?
