Hi,

 if you use latest pro release, that feature already added there:

1. You can create any port group, for example with exclude all shutdown ports:



2. now you can add this group to sensor/status entity alert group as "Sensor Measured Port Group":

+1 for please fixing this

 

I really like the ability to create alert checkers that cover everything, creating more exceptions makes alerting more difficult to maintain.

 

Also, Adam, I just purchased an enterprise license, we’re moving forward with observium for our prod environment. Great tool, good name, Adams must think alike 😝

Hi All

Yes I agree this is an issue too.  I was trying to get around it by creating a port group of all ports that were in a non-admin down state and set the alerts to use that, but I cant see to find a way to add a port group to the alert sensor.

Can this please be fixed?

Thanks

Richard

I noticed this too, it was like if the SFP was inserted, it’d still throw an error because the transceiver tx/rx limits were technically still out of spec. There needs to be logic to check for the interface status first, then disable the thresholds/alerts if down.

 

I had just considered removing optics for ports that were shut, but kinda annoying for sure.

Subject: [Observium] Low dbm sensor alerts for shutdown interfaces

 

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  Threshold

Port       (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.
