Metrics Data

This directory contains per-version snapshots of Jaeger's metrics in YAML format. The files are generated automatically by the jaeger main repo release workflow and follow the same versioned directory convention as data/cli/.

Structure

data/metrics/
  {version}/           # e.g. 2.17
    metrics.yaml       # combined metrics snapshot for this release

Format

Each metrics.yaml contains a list of metric entries scraped from the Prometheus /metrics endpoint of the jaeger binary during integration tests:

version: "2.17.0"
metrics:
  - name: otelcol_exporter_sent_spans
    labels:
      - exporter
      - service_name
      - service_version
  - name: otelcol_receiver_accepted_spans
    labels:
      - receiver
      - service_name
      - service_version
      - transport

The file is generated by the scripts/release/publish-metrics-to-docs.sh script in the jaeger main repository, which downloads the combined metrics artifact from the release workflow and converts it to this YAML format.
