metrics include path parameters instead of setting them as a field

@ns.route("/metadata/<string:serial_number>") results in

flask_http_request_duration_seconds_bucket{le="0.005",method="GET",path="/gateway/api/cms/metadata/77777777",status="200"} 0.0

but I would have expected it to have serial_number as a field set to 77777777 instead. Is there something I need to do for it automatically do this?

I do not believe those metrics come from this library, are you using https://github.com/rycus86/prometheus_flask_exporter? If so asking there would hopefully be able to provide an answer.

@csmarchbanks you are correct, sorry I will ask over there.
