Report unknown rather than critical for nagios agent failure

[gselvakumar]

Hi Team,
Help needed
We using nagios for monitoring Linux,AIX and windows. We have installed agent on these servers. Due to some patching activities agent gets stopped on the server and all the parameter for the server becomes critical and alert gets triggered for the all services for the server as have integrated nagios with servive now ticket is being generated for these alerts and Infra team is complaining that false being triggered by nagios .So we need to avoid such issue, we that alert as unknown instead critical.



Thanks

You can add the -u arg to the check_nrpe command definition. I also use a notification delay in my templates so transient issues like this get filtered if they resolve themselves...

# /usr/local/nagios/libexec/check_nrpe -h

No it is not working for me

The command I am using is mentioned below let me know it is right?

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H xxxxxxxxxxxxxx -t 30 -u -c  check_disk -n -a '-w 20% -c 10% -p /'

I'd suggest you run your command above from the shell as nagios when it will fail during patching, then run echo $? and post all of it here.

Thanks @gormank!

It looks right, please do what @gormank mentioned and post the output of the full commands entered over the CLI, as well as the echo $?[/icode[ so we can see the exit code.
