Monitoring of Custom scripts in NagiosXI

[tthomas]

we have script on placed in the server /path/script.sh and output of the script is characters like
 ‘OK’  if we have >=30 days of time for the certificate to expire.
 ‘ERROR!’  if it is <30 days for the certificate to expire.
Can it be possible to monitor it in NagiosXI according to the above outputs/thresholds and if yes how to monitor it.

You could have NRPE run the script, and then it will send the results of the script back to you. You would need to modify the script a bit to exit with different codes depending on what the script found. If it exits with a 0, Nagios is going to think it's okay.
