OpenMetrics is a specification that evolves the Prometheus exposition format into a vendor-neutral standard for exposing cloud-native metrics, supporting both text and Protocol Buffers representations. The repository hosts the spec, protobuf definitions, and the governance process for OpenMetrics 2.0 development.

Use cases

• expose application metrics in a standard format for Prometheus scraping
• implement a metrics exposition endpoint compatible with OpenMetrics
• understand the differences between Prometheus and OpenMetrics formats
• contribute to or propose changes to the metrics exposition standard
• parse or generate OpenMetrics text or protobuf metric data

When to choose

• you need to implement or validate metrics exposition against an open standard
• you are building monitoring tooling that consumes or produces Prometheus-compatible metrics
• you want to participate in shaping the OpenMetrics 2.0 specification

When to avoid

• you just need a client library to instrument your app - use a Prometheus client instead
• you need a runnable metrics server rather than a specification
• you need full OpenTelemetry metrics semantics
