Remove tap, fwpr, fwln from Network interface discovery

[Florian]

Hi there,

I’m trying to configure the Network interface discovery to my needs.

I want the service names in the following format “Interface eno1” and not something like “Interface 81”. Also I want to exclude interaces like tap.., fwpr.., fwln…

One of my hosts looks like this where the first entry should be removed and the second entry is in the right format.

I tried to reset the host’s services with “remove all and find new” but that didn’t work.

I probably have something wrong with my config for “Network interface and switch port discovery“, maybe you can find the error. This is the only enabled rule for discovery.

Thank you for your help

CMK version: Checkmk Raw Edition 2.4.0p13

After your correct rule you have to create a second rule like this.

This rule should have the same condition block as the first rule.

In your case there are other rules existing that will find the unwanted tap interface but with index instead of description as name.

Thank you.

I got it working with an rule matching the unwanted interface descriptions and with “do not discover single interfaces”.
