As far as I know, Cisco doesn’t support sending device telemetry in OTLP format at the present time, only MDT (Model-Driven Telemetry).

The only option I’m aware of for getting MDT into Grafana currently is to use Telegraf with one of the following plugin combinations:
-Input: gnmi (for dial-in) or cisco_telemetry_mdt (for dial-out)
-Output: influxdb (the standard recommendation), or the prometheus plugin (which provides a exporter that you can scrape, but results in excessively verbose / borderline-unusable metric names)
