## Introduction

Prometheus integration for Starlette.

## Requirements

* Python 3.8+

* Starlette 0.12+

## Installation

```console

$ pip install starlette-prometheus

```

## Usage

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

```python

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.
