I have done snmp extension on a remote device. But I am not able to add it as a service in LibreNMS because the check type “Passive” does not appear in the menu, (Note: the extension script is working fine since I can see its results when doing SNMP capture).
I have checked several solutions, and they all assume that it needs to activated from the Poller menu. But it does not appear in the Poller menu. Can you suggest a method to do what is needed display Passive in “Check Type” menu.
