"No performance graphs were found for this host."

Post by rainbow_ya »

Nagios doesn't show the performance graph for the command check_snmp_load.pl, any idea why?
I see the following message on "Performance Graphs" under "Host Status Detail". No performance graphs were found for this host. The performance data line is showing green.

This indicates that the underlying graphing software (PNP) was unable to find an performance data that could be graphed. This might mean that the plugin either doesn't produce performance data, or that the data doesn't conform to the plugin guidelines. You can see what performance data (if any) is being returned from the plugin by click on the "Advanced" tab and looking at the "Performance Data" line.

Thanks for the screenshots. As you can see in the first screenshot, the "Performance Data" line is blank. That means there isn't any data for the graphing tool to generate an RRD file. It seems like the check_snmp_load.pl plugin doesn't support performance data. If you know the OID for getting load info from your switch, you could use the more generic check_snmp plugin which does support performance data.

Just checking in - are the performance graphs being generated okay now that you've added the -f option to the command definition?

Thanks for that, I knew the error was from performance data and add "-f" to the command line to ouptut performance data.

Yes, they are generated now.

Missing Graphs

Post by fkroeger »

I can't seem to be able to view any performance graphs. I select All Graphs from the home page - each host I have setup is displayed, but no performance graphs. I can select and display other info like Trends & Host Availability.
I can see that the rrd & xml files are being updated regularly in the /usr/local/nagios/share/perfdata folders. It would appear that NagiosXI is looking somewhere else for the data?

Did you reset the system security credentials? The most likely problem is that the Nagios Core Backend password is incorrect. The password is used by XI to make backend calls to display the performance graph images. To fix it, enter the Admin menu and select the Reset Security Credentials menu option. Click the Update Credentials button to apply a new password.

Check the performance graphs again - they should be displayed.

Thanks for the tip. However.... it hasn't made a difference - still no graphs.
The only password I had changed was for nagiosadmin
I even added a character to the backend password and updated again to force it to overwrite the existing entry - still no graphs.

regards... Fred

Problem Solved:
Checking through the logs, the problem is definitely password related as I am getting Password Mismatch for nagiosadmin everytime I try to display a graph.
Solution was to change the nagiosadmin password in the Component Credentials section and then Update Credentials

What other causes could there be for "missing graphics"?
I have no errors when displaying the graphs and I verified that the rrds are being created. Permissions I believe are also fine: nagios:nagios / 666 file perms.
