Hi - wonder if someone can help with an issue around plugin timeouts I’m having, running Nagios 3.4.3 on Suse. Everyday some of my ConSol Labs check_logfiles checks begin to timeout. They run every 4mins and normally complete in a few seconds at most. When they timeout this could continue for several hours, however … the strange behaviour is that if I carry out any of the following 3 things the check runs fine and the CRITICAL state goes to GREEN, or I can simply run the check without any kind of timeout - as mentioed this check should never take 10 secs to complete. In fact changing the timeout value to 45 secs makes absolutely no difference at all. Restarting Nagios makes no difference.
-
In Nagios, “Re-schedule the next check of this service” - the check runs just fine.
-
Run the check from the command line on the Nagios server - the check runs just fine.
-
Run the check from the command line on the target server - the check runs just fine.
Has anyone come across this kind of behaviour before, or any ideas what might be wrong?
Thanks - Julian.
