I’m trying to monitor the degradation of the SFPs used in our backbone connections. I’ve been looking into the collection of alert rules for sensor_limit_low, but that’s not enough: I’d like to know, when the degradation starts (not, when the devices thinks, it’s time to exchange the SFP).
I’ve been tinkering along the edges of curve sketching on the dBm values of the corresponding RRDs, but didn’t find anything inside LibreNMS, that could aid me on that trip. Before pulling out rrdtool and trying to bring the outcome of a derivation back into LibreNMS, I’d like to ask the community:
How are you monitoring the degradation on your fiber connections? Is it more than checking on sensor_limit_low (to see if the dampening crosses a certain value)? Any recommendations on how to spot the beginning of the degradation?
