CPU Usage in performance graph is not working

[angus]

My CPU useage perf graphs are no working. When i click on them i only see "No Data to Display". October 13th is the last time i have history in the perf graph. This is only affecting my NCPA servers.

I read through this post but i didn't see the section mentioned on the Admin tab. https://support.nagios.com/forum/viewto ... =6&t=28385

Please assist.

Thanks.

Thinking back, this may be in relation to changing the CPU monitoring to Aggregate, combining all the CPUs into one. i hope this helps.

Did the graphs stop working when you changed the monitoring to aggregate? The reason I ask is because this thread may be related to what you're experiencing. https://support.nagios.com/forum/viewto ... 10#p135966

I removed CPU_Usage.rrd and xml from a couple servers but it hasn't repopulated. How long does this take or do i need to make a manual change?

Usually they take about 15 minutes before data starts showing up.

Did the .rrd re-generate?

If not, is npcd running?

Can you send a screenshot of the Advances tab in the Service status detail page?

[angus]

The RRD and XML did not recreate. Attached is a SS of one of the servers.

Thanks.

Run the following commands and show 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

Note: If you are using ramdisk, run the following commands instead:

Code: Select all

ls /var/nagiosramdisk/spool/xidpe | wc -l
ls /var/nagiosramdisk/spool/perfdata/ | wc -l
ls /var/nagiosramdisk/spool/checkresults/ | wc -l

Is npcd running?

Code: Select all

service npcd status

What are the permissions on the RRD & XML files, and the directory?

Code: Select all

ll /usr/local/nagios/share/perfdata/<hostname>
ll -d /usr/local/nagios/share/perfdata/<hostname>

Substitute <hostname> with the actual hostname of the host to which the "CPU Usage" check is added.

Do you see any relevant information in any of these files?

Code: Select all

/var/log/cron

I'm not much of a linux guy. I am not sure what i am looking for in those logs.

Thanks.
