Telemetry Capabilities of Cloud-Native Router

SUMMARY Read this topic to learn about the telemetry data available from Juniper Cloud-Native Router.

JCNR Telemetry

Juniper Cloud-Native Router comes with telemetry capabilities that enable you to see performance metrics and telemetry data. The container contrail-vrouter-telemetry-exporter provides you this visibility. This container runs alongside the other vRouter containers in the contrail-vrouter-masters pod.

The telemetry exporter periodically queries the Introspect on the vRouter-agent for statistics and reports metrics information in response to the Prometheus scrape requests. You can directly view the telemetry data by using the following URL: http://host server IP address:8070. The following table shows a sample output.

Note:

We've grouped the output shown in the following table. The cloud-native router does not group or sort the output on live systems.

Prometheus is an open-source systems monitoring and alerting toolkit. You can use Prometheus to retrieve telemetry data from the cloud-native router host servers and view that data in the HTTP format. A sample of Prometheus configuration looks like this:
