Hello Avi When you send the nrpe check from the master cli, what is the output you get? Can you also share the configuration of the service definition? Regards ---

I have not encountered this before, can you confirm that perfdata feature is enabled on the Icinga master ? What can you see about these checks in the debug log ? ---

Have you tried using the `-2` switch of the check\_nrpe plugin and see if that changes anything? On the command line the check shows the performance data, but not in Icinga Web 2, if I understand you correctly? As you are using Graphite for displaying the graphs the `perfdata` feature is not needed. ---

Ah, it is the check\_disk plugin of the nagios-plugins project used here. Here is a bug concerning your problem: > > > I think this is maybe some backward compatibility issue, but the documentation doesn't mention this, and this is confusing: > help: > \-m, --megabytes > Same as... Add the`-m` switch to your command line, and all should be fine. I’m not sure why they so often fiddle with the perf data output… (happend to check\_icmp recently as well) and then break compatability… ---
