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.

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

Censorship does not need to be complete to be highly effective. Almost all

We (NIST) have released a new version of the NIST RPKI Monitor (v2.0):

We are open to adding more features and analyses based on user feedback. Your
comments/suggestions are welcome. Thank you.

It's not purpose-built, but you may find a traveller hook / Shrum tool
useful. Carolina Roller is one manufacturer.
