Sounds good. Glad to get it done now until no results are coming next week!

Okay, so I got fed up waiting to see if this works;

So I've created a Linux box at home, set it to monitor my CPU usage. Purposely set the CPU to trigger at 40% and then at 50%, since I game a lot this should happen frequently. I'll let you know tonight if this works.

Nice idea. Let us know what you come up with!

Right, so i've triggered an alert. Nagios is showing as Critial, but no case in OTRS.

Doesn't look like our first attempt has worked. Can we look at any logs?

This is what i found in the nagios.log

Code: Select all

nathan@ubuntu:/usr/local/nagios/var$ tail nagios.log

but i can see now that the eventhandler should be in the libexec folder, rather than the /usr/local/nagios/ dir

Try moving the files to the /usr/local/nagios/libexec/eventhandlers/ directory, and make sure to make they are executable as well.

As these bash scripts play a critical role, this could be the cause of it not working.

its in the right place and they are set as chmod -x but still it fails

What are the rest of the permissions on the folder?

Code: Select all

ls -l /usr/local/nagios/libexec/eventhandlers/

Its okay, i just realised I made a rookie mistake, if you look at the last note, check the folder name... i missed the s off eventhandlers. Here's the new log;

Code: Select all

1453325867] wproc: NOTIFY job 2 from worker Core Worker 3632 is a non-check helper but exited with return $
[1453325867] wproc:   host=marvin; service=CPU Load; contact=nagiosadmin

[1453325867] wproc:   stderr line 01: /bin/sh: 1: /bin/mail: not found
[1453325867] wproc:   stderr line 02: /usr/bin/printf: write error: Broken pipe

[1453326194] SERVICE EVENT HANDLER: marvin;CPU Load;CRITICAL;SOFT;1;host-notify-otrs

So this looks like its worked, but OTRS isn't creating the case!
