OpenTelemetry Prometheus Exporter

|pypi|

.. |pypi| image:: https://badge.fury.io/py/opentelemetry-exporter-prometheus.svg :target: https://pypi.org/project/opentelemetry-exporter-prometheus/

This library allows to export metrics data to Prometheus <https://prometheus.io/>_.

Installation

 pip install opentelemetry-exporter-prometheus

Limitations

No multiprocessing support: The Prometheus exporter is not designed to operate in multiprocessing environments (see #3747 <https://github.com/open-telemetry/opentelemetry-python/issues/3747>_).

AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

Exports OpenTelemetry metrics to Prometheus for monitoring and observability. Bridges the OpenTelemetry metrics pipeline to Prometheus scrape endpoints.

Low install friction with a pure-Python wheel. Actively maintained (28 days since last release) with recent commits and 2586 repository stars. Supports Python 3.10–3.14.

Apache-2.0 permissive license allows commercial and private use with minimal restrictions, typical for OpenTelemetry ecosystem projects.

Usage

pip install opentelemetry-exporter-prometheus

from opentelemetry.exporter.prometheus import PrometheusMetricReader
from opentelemetry.sdk.metrics import MeterProvider

reader = PrometheusMetricReader()
meter_provider = MeterProvider(metric_readers=[reader])

Requires Python ≥3.10. No multiprocessing support; not designed for multiprocessing environments.

Verdict: A stable, actively maintained exporter for routing OpenTelemetry metrics to Prometheus. Low install friction and permissive licensing make it a straightforward choice for Prometheus-based observability, but multiprocessing limitations should be evaluated against your deployment model.
