CPU Usage in performance graph is not working

[vincheesel]

Hi,

Since the latest update (Nagios XI 2014R1.3)

The CPU Usage in performance graph tab is not working - however I can access the CPU Usage graph via the graph icon on the Service Status page.

Every other graph seems to work - only the CPU Usage is affected.

Is this a known bug with the latest release?

Any ideas on how to fix?

Are you using highcharts or the "old style" graphs? Have you try switching from one to the other to see if the graphs will be updating properly?

Admin->Use Highcharts for Perfdata Graphs = checked/unchecked->Update Settings

Are the rrds updating?

Code: Select all

ll /usr/local/nagios/share/perfdata/<hostname>/ | grep -i cpu

Can you click on one of the CPU services (Home->Service Detail), go to the "Advanced" tab, and show us a screenshot of this page?

Thanks for your reply

Interesting - when I untick "Use Highcharts for Perfdata Graphs" CPU usage works.

as requested

Code: Select all

-rwxrwxr-x 1 nagios nagios 384736 Apr 13 21:26 CPU_Usage.rrd
-rwxrwxr-x 1 nagios nagios   2130 Apr 13 21:26 CPU_Usage.xml

Any ideas on how I can fix this when Highcharts is enabled?

At the moment, no direct thoughts. What check in particular are you running in this case? windows, linux, mac, etc? snmp, wmi, local agents?

Thanks it's the Windows check_nt command

We are using the default Windows server wizard

When did you upgrade? Are you sure that graphs were working prior to the upgrade. The timestamps of "CPU_Usage.rrd" and the "CPU_Usage.xml" show April 13...

You can delete these two files, wait for 15-20 min to see if the graphs will start updating. Note: You will lose the old cpu usage historical data.

I upgraded on the 23rd of July, it was definitely working around the 17th - I did apply a few yum updates just before the upgrade - not sure if that had anything to do with it.

Sorry I think I sent you stats to a disabled service earlier..

Its definitely collecting the stats, I deleted and it did recreate after 10 minutes - however the graph still doesn't appear

Code: Select all

-rwxrwxr-x 1 nagios nagios 384736 Jul 29 09:05 CPU_Usage.rrd
-rw-rw-rw- 1 nagios nagios   2138 Jul 29 09:05 CPU_Usage.xml

Any other suggestions?

I was able to recreate the issue on one of my test boxes. I am going to do some more digging into it. If CPU perfgraphs break on my other text box, I will be filing an internal bug report.

I wonder, is this issue persistent across multiple browsers?

Since you've shown that XI is collecting the perf data, and you can view it elsewhere, it seems like it's just not getting to your web UI in this very specific instance.

Sounds like lmiltchev is on the case

I tested Google Chrome, and Internet Explorer 11. Same issue

Thanks,
