Unable to integrate Juniper Routers with gnmic

[arbabali999]

I have successfully integrated Nokia Routers with gnmic and successfully visualizing telemetry stats on Grafana. But with Juniper, i am unable to retrieve any data using get command, hence, it's not working using subscription as well. PFB for reference.

gnmic -a 10.1.1.1:57400 -u admin -p admin--insecure -d get --path /interfaces/interface/state/counters

When i used --encoding, same issue arise.

[karimra]

You are missing the --encoding flag. you can either pass it as a flag or part of the config file.

[arbabali999]

As I mentioned earlier, when I passed --encoding as flag with get, it still showed same error.

[karimra]

can you show an example of how you did that ?

[arbabali999]

PFB.

[karimra]

you should check with Juniper which encodings are supported

[hellt]

Afair Juniper didn't play well with get requests; users were forced to use subscribe rpc

[arbabali999]

So, if i use encoding in config file, will it impact Nokia Routers as well because it is visualizing successfully for Nokia Routers.

[karimra]

you can set the encoding per subscription: https://gnmic.openconfig.net/user_guide/subscriptions/#file-based-subscription-config

[arbabali999]

Yes, get doesn't work with Juniper. I used encoding in config file and it start scrapping data to Prometheus.

Thanks.
