I am not sure why you edited out the contents here, but if you want to use this middleware to send metric data to grafana, I suppose you'd just write a client which implements the very basic TimingClient interface. I am not an expert on using "plain old statsd", but I'd guess it would go something like this (the README example, slightly adapted):

import uvicorn
import statsd

from starlette.applications import Starlette
from starlette.responses import PlainTextResponse
from timing_asgi import TimingMiddleware, TimingClient
from timing_asgi.integrations import StarletteScopeToName


class StatsdTimings(TimingClient):
    def __init__(self, host: Optional[str] = None, port: Optional[int] = None)
        if host is None:
            host = 'localhost'
        if port is None:
            port = 8125
        self._statsd_client = statsd.StatsdClient(host, port)

    def timing(self, metric_name, timing, tags):
        # plain-old-statsd does not support tags
        self.statsd_client.timing(metric_name, timing)


app = Starlette()


@app.route("/")
def homepage(request):
    return PlainTextResponse("hello world")


app.add_middleware(
    TimingMiddleware,
    client=StatsdTimings(),
    metric_namer=StarletteScopeToName(prefix="myapp", starlette_app=app)
)

if __name__ == "__main__":
    uvicorn.run(app)
