I have long service check and I get "(Service check timed out after 87.39 seconds)". How do a increase the timeout value? I have set the timeout in the service checks themselves but the don't seem to be working. The service check completes from the command line but not within Nagios XI

Nagios Core also needs the timeout increased (there is a global timeout).

CCM
Advanced > Nagios Core Main Config
service_check_timeout=xxxx
Click Save and then Apply Config

To determine a good timeout value, time your command at the cli by pre-pending the command with "time":

Thanks, that worked.

Excellent
