Available Metrics Catalog

This page documents all telemetry metrics available from Nokia SROS and SR Linux devices in the BNG lab.

Metric Overview

Metrics are collected via gNMI streaming telemetry at 5-second intervals and exported to Prometheus. Metric Types:

Counter: Cumulative value that only increases (resets on restart)
Gauge: Value that can increase or decrease
String: Converted to labels in Prometheus

Naming Convention:

SROS: /state/ prefix removed by gNMIc processor
SR Linux: YANG path structure preserved
Underscores separate path elements
