Nagios Support Forum

Hello,

Following upgrade to the latest release, the performance graphs are no more displayed. We've unsuccessfully tried the steps in this link : http://support.nagios.com/wiki/index.ph ... _Displayed
How can we sort it out?

Thanks
Patrick

Few questions:
1. Do the "graph explorer" graphs work?
2. Is npcd running? 3. What is the output of (post in code wraps): 4. Do a running tail on the httpd error log and while it is tailing try to view a graph: (kill it afterwards and post the output in code wraps)

Yes, Graph Explorer works and npcd is also running.

So we are talking about the classic PNP graphs located at Home > Services > "Service Name" > Performance Graphs

Do you see any errors on this page? Can you run the following command, and then try to load one of your service's graphs through this page?
let us know what the output is when loading the page.

There is no error in /var/log/httpd/error_log while trying to access performance graphs.
Only this is reported on the GUI : "No performance graphs were found for this service".

Are all pnp graphs missing? Did you by chance upgrade pnp4nagios (this is not suggested)?

Yep! all pnp graphs are missing.
No, I haven't upgraded pnp4nagios.

Just to make sure that pnp4nagios is configured correctly, lets do an in-place reinstall of the component:

pnp reinstalled, performance graphs still not displayed.

Are you able to see the graph explorer graphs?:

Home > Graph Explorer

Can you post the output of the following: And then run those two commands again about 5 minutes later and compare the output, please show all 4:
