Prometheus Exposition Format / OpenMetrics

The text-based exposition format that every instrumented target exposes (typically on /metrics) and that the Prometheus server scrapes over HTTP. The format evolved into OpenMetrics, a CNCF Sandbox specification that is the standardized successor; both are scrape-compatible with Prometheus. Defines counters, gauges, histograms, summaries, and (in OpenMetrics) info, stateset, gaugehistogram, and exemplars.

Prometheus Exposition Format / OpenMetrics is one of 5 APIs that Prometheus publishes on the APIs.io network.
