[Observium] Observium doesn't show interfaces within VPRN on Nokia routers

Hi Observium team, We are using Observium as a main tool to monitor our router interfaces and collect SNMP stats. We recently replaced our Juniper routers with Nokia SR 7750. We noticed that Observium doesn't work very well with Nokia routers. Observium can only show the interfaces in the master instance, not the interfaces within VPRN or VPLS instances (Nokia call those interfaces SAPs).

To be able to see interfaces within VPLS or VPRN, we need to enable two other MIBs, TIMETRA-SAP-MIB and TIMETRA-VRTR-MIB. We are not sure how to enable those two MIBs. Do we need to add them manually?

This is the MIBs enabled on the Nokia router (default). [cid:ece89bfc-3ae2-4dcd-9c7c-641c3978f803]

Any suggestion is greatly appreciated.

Thanks, Tao
