[j-nsp] Junos Telemetry Interface

Sun Apr 12 23:43:44 EDT 2020

You’re welcome Colton.  I understand there are 2 different ways to do telemetry on Juniper.  One called Native and the other called gRPC/openconfig.  I’ve done the Native form.  I think the native form is a configured form where by which the network device constantly streams the sensor objects… and conversely, the gRPC form is subscription based where the management app/computer, subscribes to the network device to receive telem data objects.

I understand the native form to be executed in hardware near the monitored object….and because of this, highly scalable.    And the grpc/openconfig form runs on re cpu.

I don’t think we’ve gotten native telemetry to work on ACX.  But I have it running on MX960’s.

I understand the grpc/openconfig method requires you to download some code/software to the network device.

Collector I use is the OpenNTI project.  Grafana (web ui) (or a less known Cronograf, which I actually use and like), InfluxDB (TSDB), fluentd, and other components.  I must credit Dave, my coworker and resident Linux genius in assisting my with the server side collector setup.  Some helpful/related links below….

Aaron,

Thanks, this is indeed helpful. What collector are you using to store and view this telemetry data? Also, have you had any luck with getting JTI to work on your ACX gear? This only JTI feature is see for the ACX line according to the feature explorer is: https://apps.juniper.net/feature-explorer/feature-info.html?fKey=8978 <https://apps.juniper.net/feature-explorer/feature-info.html?fKey=8978&fn=Specify%20Routing%20Instance%20for%20JTI> &fn=Specify%20Routing%20Instance%20for%20JTI I am not sure if that means it fully supports JTI or not.

Not sure if this is what you are looking for, but here are some of the
sensor agents that I enabled on my MX routers....

Maybe it's the linecard or interface specific ones that give me the bits in

Instead of monitoring Juniper equipment by SNMP with 5 minute polling we
would like to use streaming telemetry to monitor the devices in real-time.
This requires the Junos Telemetry Interface.

Looking in the Juniper Feature Explorer, Junos Telemetry Interface is not a
feature, but rater a whole category in the feature explorer, with multiple
features under it. What feature am I looking for to be able to monitor the
interfaces in real-time, and see how much bandwidth flows across them
similar to SNMP?

The ACX platforms only support the Specify Routing Instance for JTI
feature?
