Nagios Event handler not working

Posted: Fri Aug 03, 2018 3:17 pm

We have two environment, in one of the environment, we are using event handler without any issue for the last one year. However, we are deploying the same script in another environment, but its not working.

we have written this script to trigger ticket to our ticketing system, if a service or host goes down to "HARD & DOWN for host and CRITICAL & HARD" for service . (note: same script working well in another nagiosXI enterprise environement).

I've tried bring down a service using submit passive check and saw the logs, bizarrely event handler executing after the service turn to normal state and NOT after "CRITICAL & HARD" state.

so kindly help me to resolve the issue, IS ANY CONFIGURATION IS WRONG IN ANY CONFIG FILE TO MAKE EVENT HANDLER TO WORK WELL ?
Sharing the nagios.cfg and resource.cfg file and my event handler script.

Attached the screenshot which showing event handler triggering service turned to OK state.

Also, FOR YOUR INFORMATION I've tested event handler already as per the NagiosXI document by using "check_dummy". ITS WORKING PROPERLY.

Attached profile.

In the attached screenshot, its clearly shows that event handler script triggering after the state changes to OK.

the event handler points to

Code: Select all

$USER2$/event_handler_service
however
$USER2$ is not defined in resources.cfg

Changed the resouce config. (see below).

Now again triggered the event handler by using passive submit, now again event handler script triggering after service state changes to OK only.

I dont know why its behaving like this, since I used to configure many event handler in our another environment, (Note: This is our new environment, triying to configure for the first time).

Attaching the screenshot of commands section.

Sending the nagios.log. See its executing the script after service state changes to OK. And also attaching the screenshot of settings of that service.

Now reduced the check Interval - 2 , Max check attenpt - 1. And tried to bring down the service by passive submit.

See the logs now. STILL SAME SCENARIO
