so interface counters is a thing.... but streaming telemetry (with occasional 
push) can do much more:
for example one can stream (at least from rare/freertr)
- bgp states (up/down) (even from an implicit source such as bmp!)
- igp topology/link/whatever changes (in this case freertr must be a router 
node)
to influx/grafana/whatever, where from, you can alert within seconds!
imho it should ring the bell?! :)
