How the Prometheus community is investing in OpenTelemetry

The Prometheus community is actively integrating OpenTelemetry, an observability framework, to enhance its compatibility and reduce vendor lock-in, with significant steps taken to ensure bidirectional support between the two systems. This collaboration has led to the creation of specifications and implementations that allow seamless integration of Prometheus metrics into the OpenTelemetry Collector. As part of this initiative, Prometheus is preparing for the release of version 3.0 in 2024, which will feature OpenTelemetry Protocol (OTLP) support. The community is addressing challenges such as support for UTF-8 metric names, native resource attributes, and Delta temporality handling, while striving to ensure these updates do not disrupt existing Prometheus operations. The Prometheus team is calling for contributors to help with these developments and has structured efforts to make the maintainer process more accessible. This marks a significant evolution for Prometheus, promising enhanced interoperability and functionality without major disruptions for current users.
