Server quickstart

from aiohttp import web
from aiohttp_prometheus_exporter.handler import metrics
from aiohttp_prometheus_exporter.middleware import prometheus_middleware_factory

async def hello(request):
    return web.Response(text="Hello, world")

app = web.Application()
app.add_routes([web.get('/', hello)])

app.middlewares.append(prometheus_middleware_factory())
app.router.add_get("/metrics", metrics())

web.run_app(app)

Client quickstart

import aiohttp
from aiohttp_prometheus_exporter.trace import PrometheusTraceConfig

async with aiohttp.ClientSession(trace_configs=[PrometheusTraceConfig()) as session:
    async with session.get('http://httpbin.org/get') as resp:
        print(resp.status)
        print(await resp.text())
