Re: link monitoring

2021-04-30 Thread Alain Hebert

    Yes the JNP DOM MIB is what you are looking for.

    It also the traps for warnings and alarms thresholds you can use 
which is driven by the optic own parameters.

    ( Human Interface: show interfaces diagnostics optics  ] )

    TLDR:

        Realtime: Traps;
        Monitoring: DOM MIB;

https://kb.juniper.net/InfoCenter/index?page=content=KB36074=MX2008=LIST 



In other equipment sometimes it's found in a sub-tree of SNMP adjacent 
to optical DOM values. Once you can acquire and poll that value, set 
it up as a custom thing to graph and alert upon certain threshold 
values in your choice of NMS.


Additionally signs of a failing optic may show up in some of the 
optical DOM MIB items you can poll: 
https://mibs.observium.org/mib/JUNIPER-DOM-MIB/ 



It helps if you have some non-misbehaving similar linecards and optics 
which can be polled during custom graph/OID configuration, to 
establish a baseline 'no problem' value, which if exceeded will 
trigger whatever threshold value you set in your monitoring system.

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 monitor system completely
failed to warn about the failure. Had to find the bad link by
traceroute (mtr) and observe where packet loss started.

The link was between a Juniper MX204 and Juniper ACX5448. Link
length 2 meters using 2 km single mode SFP modules.

What is the best practice to monitor links to avoid this
scenarium? What options do we have to do link monitoring? I am
investigating BFD but I am unsure if that would have helped the
situation.

Thanks,

Baldur
