Nagios Support Forum

Our Nagios suddenly stopped showing performance graph/data for after Oct 16th. The performance data before Oct 16th is still able to be shown, but after the date, it is all blank. I have tried rebooted the machine, no help. The system status shows OK, with 6 green check marks.

I check the file system, it looks a lot performance data are stuck in spool folder. Anyone has any idea? Our version is 2012R2.8c

Thanks a lot

Where exactly - in xidpe, perfdata?

Can you run the following commands and show us the output?
Having too many files in "/usr/local/nagios/var/spool/xidpe" directory may indicate that cron is/was not running. After cron runs, it moves these files to the perfdata dir. Having too many files in the "/usr/local/nagios/var/spool/perfdata" directory means that npcd is/was not running and not processing these files. Perhaps, the load on the server exceeded the "load_threshold" value in the "/usr/local/nagios/etc/pnp/npcd.cfg".

See below, looks npcd issue, the thing I dont understand is we are having the issue starting from Oct 16th, which is corresponding with the npcd log (10-15-2015), but looks on (07-10-2015) the similar issue were logged however we didn't have the issue from then...

any idea how to hix?

Can you post the output of the following -
grep "TIMEOUT =" /usr/local/nagios/etc/pnp/process_perfdata.cfg

TIMEOUT = 5

Try following this guide to make changes to two things, your Perfdata Timeout, and NPCD load threshold.
https://support.nagios.com/wiki/index.p ... ta_Timeout

Set your TIMEOUT to 20, and the load_threshold to 10x the amount of cores your system has.

It works now, thanks a lot!

Glad to see this worked! I will now close this thread, feel free to open another if you need more assistance.
