opentelemetry-exporter-otlp-proto-http
OpenTelemetry Collector Protobuf over HTTP Exporter
Decision gist · record as of 2026-08-14
Yes. This is a stable, actively maintained exporter for a standard observability protocol. Install it if you are using OpenTelemetry in Python and need to send data to a Collector over HTTP. Low install friction, no known vulnerabilities, and permissive licensing make it a straightforward choice for observability integration.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; an OpenTelemetry Collector must be running and accessible.
- Low friction installation with a pure-Python wheel.
- Actively maintained with recent releases.

What it is and what it does
This package is an exporter for the OpenTelemetry Python SDK that sends observability data to an OpenTelemetry Collector using the OpenTelemetry Protocol with Protobuf serialization over HTTP. It acts as a bridge between your instrumented Python application and a centralized collector, enabling you to aggregate telemetry from multiple services and forward it to observability backends.
The exporter integrates with the standard OpenTelemetry SDK via processor and exporter interfaces. It depends on googleapis-common-protos, opentelemetry-api, opentelemetry-sdk, requests, and typing-extensions—all stable, widely-used packages. The library is in Production/Stable status, actively maintained, and supports Python 3.10 through 3.14.
Use it for
- Send distributed traces from a Python microservice to a centralized collector for correlation and analysis.
- Export observability signals alongside traces to correlate performance data with application behavior.
- Integrate Python applications into an observability pipeline that feeds multiple backends.
- Batch and buffer telemetry data locally before sending to reduce network overhead.
- Monitor and troubleshoot production systems by exporting real-time observability signals to collector infrastructure.
