Prometheus exporter force using embedded httpserver

[ysma500]

First time posting in open source project 😮 ...

So I'm in a team using Go's implementation of Opencensus w/Prometheus_Exporter. For a client I need to port an existing app to Python.

In Go's implementation the PrometheusExporter initialisation ultimately returns an Handler that you can in turn pass to what ever WebServer implementation you have alongside the rest of your services.

In Python's implementation, there's an httpServer that is started to do the serving of metrics directly. Would it be possible to tear it off and return an Handler like BaseHTTPRequestHandler or something along thoses lines to have more control on how it's exposed?

Server is started in opencensus.ext.prometheus line.277 .
Thanks and great project btw,

Assuming that the MetricsHandler that the prometheus client is using under the hood is what you want here, I think it would be fine to add a get_handler method to the prometheus client alongside serve_http.

If you make this change I can help review.
