Prometheus Metric Exporter for OpenTelemetry
Decision gist · record as of 2026-08-14
Yes, if you are using OpenTelemetry for metrics and need Prometheus integration. The package is actively maintained, has low install friction, and carries a permissive license. However, note the beta status (0.65b0) and the hard constraint against multiprocessing—verify both fit your use case before committing to production.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later.
- Does not support multiprocessing environments—single-process applications only.
- Low friction installation with three stable runtime dependencies (opentelemetry-api, opentelemetry-sdk, prometheus-client).

What it is and what it does
This package bridges OpenTelemetry's metrics collection framework with Prometheus, allowing you to instrument your application with OpenTelemetry and expose those metrics in Prometheus's native format. It acts as a metric reader that converts OpenTelemetry metrics into Prometheus-compatible output, typically served over HTTP for Prometheus to scrape.
The exporter depends on opentelemetry-api and opentelemetry-sdk for metric collection, and prometheus-client to handle the HTTP endpoint and metric formatting. It's designed for single-process applications; multiprocessing is not supported. The package is actively maintained and supports modern Python versions (3.10 through 3.14), though it remains in beta status.
Use it for
- Instrument a Python service with OpenTelemetry and expose metrics to an existing Prometheus monitoring stack
- Export application metrics (requests, latency, errors) from a web service for Prometheus scraping
- Integrate OpenTelemetry observability into a microservice that feeds metrics to a Prometheus time-series database
- Replace or supplement direct Prometheus instrumentation with OpenTelemetry's vendor-neutral metrics API
- Set up metrics collection for a single-process application without multiprocessing complexity
