starlette-prometheus 0.9.0

Prometheus integration for Starlette

Starlette Prometheus

Introduction

Prometheus integration for Starlette.

Requirements

• Python 3.6+
• Starlette 0.9+

Installation

$ pip install starlette-prometheus

Usage

A complete example that exposes prometheus metrics endpoint under /metrics/ path.

from starlette.applications import Starlette
from starlette_prometheus import metrics, PrometheusMiddleware

app = Starlette()

app.add_middleware(PrometheusMiddleware)
app.add_route("/metrics/", metrics)

Metrics for paths that do not match any Starlette route can be filtered by passing filter_unhandled_paths=True argument to add_middleware method. Note that not turning on this filtering can lead to unbounded memory use when lots of different routes are called.
