Nagios Support Forum

Hi Team,

We are continuously getting Monitoring Engine Status Process State red.

On checking, we could see that there is a TIMEOUT error on perfdata.log. Attached the screenshot.

So we are going to increase the timeout value for perfdata processing on process_perfdata.cfg from 40 to 60 or 80.

Our question is, Will this increase in timeout cause any performance issues?

===========================================================================

Current timeout value


[root@nagios pnp]# cat process_perfdata.cfg
#
# Config File for process_perfdata.pl
#
# $Id: process_perfdata.cfg-sample.in 520 2008-09-16 12:50:10Z pitchfork $
#
# process_perfdata.pl Timout
#
TIMEOUT = 40

================================================================

Thanks

HI,

Our question is, Will this increase in timeout cause any performance issues?

No, that won't affect the performance. However, there is max load threshold for NPCD, and increasing this too much will cause problems since the performance process will take as many resources as you allow it to.

That said, issues with the performance graph normally do not cause the monitoring engine to stop.

Do you have enough memory and disk space? Check the nagios.log for error messages.

Hi,

The specs look good. Did you find anything errors standing out in the nagios log? Please PM the system profile so we can help troubleshoot this for you.

Hi Benjamin,

We could not see anything unusual in the Nagios log files.

Send you the system profile as PM to you.

Please have a look.

Thanks

Hi,

I'm not seeing anything in the logs related to the nagios process crashing or stopping. Memory and disk space are good. Are you still getting notifications from the system? Are you setting check results being updated in the GUI? How often is the process stopping?

I noticed you have livestatus integrated, are there any other customizations on this server?

Since the database is offloaded the log was not included in the profile, can you retrieve this from the remote host and upload it to the ticket?

Thanks,
Benjamin
