Nagios Support Forum

Hello all,

we are running some basic checks via SNMP polling like the state of the power supply of a cisco router with the following command:

check_xi_service_snmp -p 161 -o enterprises.9.9.117.1.1.2.1.2.48565389 -C whatever -P 2c -l "Power" -m CISCO-ENTITY-FRU-CONTROL-MIB -r "on"

With the MIB file Nagios can determine the state which works fine. Anyway, Nagios thinks that a performance graph is necessary for this service. How can I avoid that empty graphs like in the attachment are shown?

Thanks a lot and best wishes

This check must be returning some type of performance data. What output is listed at --> Home --> Service Details --> Click the service --> Advanced --> Performance data (on the left)?
How often is this check run?

Here it shows green but there is no cross to disable. Check interval is 5 minutes.

Is the "Performance data" field on the left empty or populated? If it is populated, could you post the performance data here?

If you don't need perfdata, you can simply disable perfdata processing for this service:

CCM->Services-><your service>->Modify->Check Settings tab->Process perf data = off->Save->Apply Configuration

Then you can remove the rrd & xml files for this service from the "/usr/local/nagios/share/perfdata/..."

No, as far as I remember there was no performance data in the field.

This seems to be exactly what I'm looking for . I will try this tomorrow and report.

Another related question if you don't mind: How can I rename the OID at the bottom of the charts by a human readable name or description?

And a last one: Why do the pnp4nagios graphs and the Highchart graphs co-exist in Nagios XI?

Thanks alot and best wishes

pnp4nagios display is legacy and will be mostly replaced by graph explorer. We will leave pnp4nagios in as we still use other portions of it and we want to retain reverse compatibility with integrations that rely on the pnp4nagios urls.

This is controlled by the label on the performance data in the returned check. You may be able to change it by changing the pnp template, but I doubt it.

This works fine for me, thanks a lot .

So you mean, there is no easy way to do this?

Correct, it's essentially up to the plugin, most plugins account for pushing performance data back to Nagios, though some do not.
