You are still hitting the timeout for prefdata. Increase the value from 30 to 60 and then restart npcd. Have you considered using rrdcached?

I've increased it and will monitor. I think rrdcached might already be enabled. I see this in /tmp:

[root@clesitonag1 tmp]# ls -alrt|grep rrd
-rw-r--r-- 1 rrdcached rrdcached 0 Mar 27 10:21 rrd.journal.1395930094.537011

Great. Keep us informed.

Graphs were working smoothly until a few hiccups today. The log output shows timeouts after 30 seconds, but my perfdata config is already set to 60. Any suggestions?

Was npcd restarted after the change to 60?

Code: Select all

service npcd restart

Yes. I went ahead and restarted it again, to be sure.

Just to be sure:

Code: Select all

grep TIMEOUT /usr/local/nagios/etc/pnp/process_perfdata.cfg
Lets kill npcd completely and restart npcd and nagios:

Code: Select all

service npcd stop
killall npcd 
service nagios restart
service npcd start

Looks good now. No timeouts seen since 3/27. Thanks!
