Nagios Support Forum

Hello,

I have recently upgraded to Nagios XI 2011r1. The performance graphs were working OK yesterday but today they have all stopped. I am using the CentOS virtual machine running in an ESX environment.

I have tried:

Restarting the server
Running "Check file permissions" - all ok
Resetting the security credentials.

Is there anything else I need to check?

Regards

You can also try restarting httpd, but, there may be a small bug that we are working on that is impacting this and we should have a tiny patch available today (hopefully).

The PNP graphing service can be restarted with the following command, it may have stopped during the upgrade:

service npcd restart


If that doesn't work, do you have any special configs on your web server like a proxy or SSL?

I run Nagios in the same environment you do and had the same issue a while back.

Look int "/usr/local/nagios/var/spool/perfdata" directory and see if the file dates match when the graphing issue started.

If the file date match, you may be having a performance issue.
The only way I was able to resolve it was ti shut down the Nagios Guest and increase the VM resources to 2 CPUS and 1GB or RAM.

Whyou restart the VM Guest the graphs should appear.
