No rrd files being created

Although I have enabled performance data on all of my hosts and some of my services, I cannot get performance graphs. I checked the server and there are no rrd files being created. I have upgraded, checked the help at http://support.nagios.com/wiki/index.ph ... h_Problems but it does not seem to have anything that addresses the failure to create rrd files. I am not sure where to go next.

Can you show the output of the following:

Code: Select all

service npcd status

ls /usr/local/nagios/var/spool/xidpe/ | wc -l

ls /usr/local/nagios/var/spool/perfdata/ | wc -l

tail -50 /usr/local/nagios/var/npcd.log

You have quite many files in the "xidpe" directory. Is crond running?

Code: Select all

service crond status
Have you tried the solution, listed below (from our wiki page here: http://support.nagios.com/wiki/index.ph ... h_Problems )
If the file count is very large, run the following commands, which should restore regular performance graphing.

cd /usr/local/nagios/var/spool
rm -rf xidpe
mkdir xidpe
chown nagios.nagios xidpe
chmod 755 xidpe
Also, it seems like you've exceeded a few times the "load_threshold", defined in the "/usr/local/nagios/etc/pnp/npcd.cfg" file. What is your hardware like?

Code: Select all

lspci
If you have 2 cores, you can double the threshold of 10 to 20 (x2), it you have a quad core - to 40 (x4) and restart npcd:

Code: Select all

service npcd restart
Let me know if this helped.

crond is running
cleaned the xidpe directory, checked ownership, set permissions
Hardware is virtual instance with two cpu and 4GB allocated.
Set threshold to 20.
Restarted service.
BINGO! We have success. Thanks!

Is this a one-time sort of thing or is there some maintenance I should be doing?

This only happens when the nagios engine stops while performance data is still being recorded or npcd hits a load/timeout limit too often (passive checks can cause this as they may continue to get written to disk).
Do us one more favor and make sure that the spool folders are not filling back up:

Code: Select all

ls /usr/local/nagios/var/spool/xidpe/ | wc -l
ls /usr/local/nagios/var/spool/perfdata/ | wc -l

They were "2" and "2".

Great. You should be all set. You may want to monitor the number of files in those two folders as it will operate as an early warning system for perfdata/npcd issues.
