We use LibreNMS and smokeping to monitor latency and dropped packets on all our links and setup alerts if they go over a certain threshold. We are working on a script to automatically reroute traffic based on the alerts to route around the bad link to give us time to fix it. Thanks Travis

If I may add one thing I forgot, this post reminded me. In the question I think it was probably a 100G CWDM4 short distance link. When monitoring a 100G coherent (QPSK, 16QAM, whatever) longer distance link, be absolutely sure to poll all of the SNMP OIDs for it the same as if it was a point to

We monitor light levels and FEC values on all links and have thresholds for early-warning and PRe-failure analysis. Short answer is yes we see links lose packets before completely failing and for dozens of reasons that’s still a good thing, but you need to monitor every part of a resilient

The Junipers on both sides should have discrete SNMP OIDs that respond with a FEC stress value, or FEC error value. See blue highlighted part here about FEC. Depending on what version of JunOS you're running the MIB for it may or may not exist.

Hello We had a 100G link that started to misbehave and caused the customers to notice bad packet loss. The optical values are just fine but we had packet loss and latency. Interface shows FEC errors on one end and carrier transitions on the other end. But otherwise the link would stay up and our
