performance data for disk check is empty

I have on disk check that shows up empty. Looking around on this forum, I found a similar post. So I did my homework!

Home/service detail - Advanced tab shows:
Performance Data: 'C: %'=35%;89;94 'C:'=65.306G;10;5;0;99.9
ll /usr/local/nagios/share/perfdata/

shows this particular host.

Code: Select all

drwxrwxr-x 2 nagios nagios 4096 Feb  3 17:41 HOST01

tail -25 /usr/local/nagios/var/perfdata.log

Check intervals are the same as other (working) checks.

Any pointers?

Do you have any files (RRDs and XMLs) in the "HOST01" directory?

Code: Select all

ll /usr/local/nagios/share/perfdata/HOST01
Is npcd running at the moment?

Code: Select all

service npcd status
It seems that the load on your system went above the default load threshold of 10, specified in the npcd.cfg...

Have you tried restarting it?

Code: Select all

service npcd restart
Run the following commands and show us the output:

Code: Select all

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

The HOST01 has both RRD and XML for this particular check.
NPCD is running
NPCD is defaul nistall. No modifications on our part. (checked against other Nagios server)
I have restarted, no difference.

ls /usr/local/nagios/var/spool/xidpe | wc -l
0
ls /usr/local/nagios/var/spool/perfdata | wc -l
0
ls /usr/local/nagios/var/spool/checkresults | wc -l
0

Follow the FAQ below and increase the logging verbosity for both perfdata.log and npcd.log. Wait 15 minutes and then check those logs again:
http://support.nagios.com/wiki/index.ph ... h_Problems

Code: Select all

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

Problem solved.

It looks like the .RRD and the .XML files were locked in some way.
We did an edit and save without actually changing something.
That got the train rolling again.
