My Prometheus is unable to scrape any telemetry data from gnmic for BGP operational state although gnmic is collecting data from the target and exposing it on port 9273.

PFB prometheus.yml and gnmic.yml. My Prometheus is unable to scrape any telemetry data from gnmic for BGP operational state although gnmic is collecting data from the target and exposing it on port 9273.

prometheus.yml:

I have verified using below command (providing one as reference) about subscription path provided in gnmic.yml that subscriptions are correct.

[ { "source": "192.168.69.38:57400", "timestamp": 1711626595652121572, "time": "2024-03-28T16:49:55.652121572+05:00", "updates": [ { "Path": "state/router[router-name=Base]/bgp/neighbor[ip-address=192.168.100.1]/statistics/session-state", "values": { "state/router/bgp/neighbor/statistics/session-state": "Established" } } ] } ]

But http://localhost:9273/metrics doesn't show anything related to BGP operational state although other metrics are reflecting.

Need assistance.

Prometheus accepts float values only, the BGP operational state is a string (Established). In order to show it in Prometheus you have to map it to a number (just like you did with the esa-health processor)

That worked. Thanks.
