Hello Team,

For network interface status we are getting unknown:no information being retrieved.


Next check attempt it's showing critical: interface status down

Can you clarify what's the reason we are getting Unknown:no information on being retrieved

Can you tell us a little more about this service check? Is this a network switch that you're monitoring? Is it being monitored via SNMP?

Yes...network switch only...it's monitored via SNMP

Is this just one interface on the switch, or are multiple interfaces experiencing this?

If it's just one interface on the switch, the first thing I would check would be whether someone is unplugging a computer from the switch at that port. SNMP responds like that when a device is unplugged from an interface.
