OpenTelemetry Prometheus Exporter

Prometheus integration for applications instrumented with OpenTelemetry.

Warning: This crate is no longer recommended for use.

Development of the Prometheus exporter has been discontinued. See the related issue. This crate depends on the unmaintained protobuf crate and has unresolved security vulnerabilities. Version 0.29 will be the final release.

For Prometheus integration, we strongly recommend using the OTLP exporter instead. Prometheus natively supports OTLP, providing a more stable and actively maintained solution.

OpenTelemetry Overview

OpenTelemetry is an Observability framework and toolkit designed to create and manage telemetry data such as traces, metrics, and logs. OpenTelemetry is vendor- and tool-agnostic, meaning that it can be used with a broad variety of Observability backends, including open source tools like [Jaeger] and [Prometheus], as well as commercial offerings.

OpenTelemetry is not an observability backend like Jaeger, Prometheus, or other commercial vendors. OpenTelemetry is focused on the generation, collection, management, and export of telemetry. A major goal of OpenTelemetry is that you can easily instrument your applications or systems, no matter their language, infrastructure, or runtime environment. Crucially, the storage and visualization of telemetry is intentionally left to other tools.
