Hello,
When I open the graph (CPU) on a server, I get "no data to display" it only shows ping status for each of the servers.
I have checked and I got all the XML and RRD files for each host in /usr/local/nagios/share/perfdata
Do you have any idea ?
In advance thank you for your support.
graph: no data to display
Re: graph: no data to display
Can you give more information?
- What's the exact check command that's running for the CPU service?
- Can you post a screenshot of the dashboard page for the service, the "Advanced" tab? There should be a field that says "Performance Data:" that lists what was last captured.

Re: graph: no data to display
I' m using Nagios plugin for cpu and memory check through nrpe command.
I don't see any "Advanced" tab" on Dashboard page. I am running Nagios XI.
Can you tell me where to find it ?
Thanks

Re: graph: no data to display
The problem likely lies in the storage mechanism for performance data graphs. The current system stores the historic data in a RRD file (stands for Round Robin Database) and unfortunately it has limitations in that it doesn't react well to any change in the data format stored. This means when you add or remove a piece of recorded data, the RRD file will reject the input entirely.
Data often changed format when the check plugin updates, or the name of the service updates and just-so-happens to be the name of another service that was previously defined for that host.
(Good news is that when Nagios XI 6.0 comes out, this whole storage mechanism will change to one that deals better with data format changes, so hopefully this won't be a problem in the future.)
We can work around it by deleting the RRD file, which will unfortunately clear the graph of historical data. Run this command to move them out of the way.

Re: graph: no data to display
I have just deleted the RRD. Performance graph icon for CPU has now disapeared.
I recreated the 2 files through touch command.
Now the graph icon is here but endless loading when I clic on it.
Any idea about this behavior ?

Please run the following command to fix permissions:
Code: Select all
chown -R nagios:nagios /usr/local/nagios/share/perfdata/aenuatvtom/
chmod 0775 /usr/local/nagios/share/perfdata/aenuatvtom/
chmod 0664 /usr/local/nagios/share/perfdata/aenuatvtom/*
