Sure, but it's ugly.
I have a nicer solution for the Juniper-DOM MIB but I came up with a quick and dirty one for the Cisco Entity Sensor MIB. Basically we skip the discovery for interfaces that are shutdown. This could be done much earlier in the code, etc, but it will work for you for now.
Each MIB has a different approach so it's up to Alan to decide on a unified solution that catches all.

Hey Luis,
Oh wow, yes please. Could you share it here in the list so that Adam can review it also?
If it makes sense and is not in conflict with other logic Adam may be able to integrate it J
For now this (see below) does seem to work.. And there are other far more important things to worry about (choose your battles etc ;) – For us our No1 missing-feature is being able to generate alerts when the [CDR] threshold is breached on an interface.
We have this fantastic mechanism for encoding the CDR’s on interfaces using ‘[]’, but no means of actually doing anything useful with it! L
We desperately want to kill of Cacti, but we cannot until Observium supports interface threshold alerting based on the interface description’s [CDR] value.
What do we have to do to make this happen Adam? It seems such a waste having [CDR] but not being able to use it?
Thanks again,
All the best, Andy.

That bothered me too. I have a small patch for that if you want it.

Hi,
Has anyone else seen the issue where after enabling an alert checker for transceiver optics with sensor_value greater @sensor_limit and sensor_value less @sensor_limit_low, alerts are still received for shutdown interfaces?
For example, on a cisco switch when running ‘show interfaces transceiver detail’, we can see;
Optical High Alarm High Warn Low Warn Low Alarm Receive Power Threshold Threshold Threshold ThresholdPort (dBm) (dBm) (dBm) (dBm) (dBm)
Te1/1/25 -40.0 1.9 -1.0 -9.9 -13.9
Te2/1/1 -40.0 1.9 -1.0 -9.9 -13.9
Etc..
Te1/1/25 admin down down
Te2/1/1 admin down down
Etc
The sensors page shows the correct thresholds etc, but shows the interface in Red (and hence is generating alerts through the checker), rather than grey (as the port is shutdown and has no fibre connected – hence -40dbm.).
The same port on the Ports page does show the interface as being grey/shutdown
Have no idea how to resolve this and stop getting transceiver alerts for shutdown interfaces? This sounds like a potential bug?
Thanks, Andy.
