Hi,
We are using Nagios XI.
Following message is continously appearing in the alert history of a host.
Caught SIGTERM, shutting down...
What does this interpret.

I think more info, such as nearby messages from nagios.log are needed.
SIG means signal, and TERM means terminate, so a process got a terminate signal from (I'd guess) NRPE or NCPA, possibly because the length of time to run a check exceeded the defined timeout.

Hello Pratap,
Thanks for reaching out today about the service shutdowns you are experiencing.
I see that there was a previous post referring to brokers, so you may want to make note of that while you are reviewing the
nagios logs looking for these error messages.
Code: Select all
cat /usr/local/nagios/var/nagios.log
Here is the configuration file '/usr/local/nagios/etc/nagios.cfg' for any brokers like ndo or mod_gearman.
Code: Select all
grep -Ei 'broker' /usr/local/nagios/etc/nagios.cfg
Thanks,
Perry
