OpenMetrics is an open, text-based standard for exposing metrics and associated metadata, including exemplars. It succeeds the Prometheus exposition format and belongs to the metrics signal ecosystem. section 5.6.2 section 5.6.4
OpenMetrics matters when choosing how metrics move between instrumented systems and backend destinations:
- Use it as an open metrics representation alongside Prometheus exposition formats. section 5.6.2
- Prefer backends supporting OpenMetrics or another open industry standard over proprietary-only formats, while checking implementation caveats. section 5.6.4
- Recognize that older environments may still emit Graphite, InfluxDB line protocol, or StatsD formats. section 5.6.2
