Request/response size in /metrics?


Hoping I could get some insight on something observability related.

I have a prometheus + grafana monitoring stack up and running using traefik metrics entrypoint on a kubernetes cluster. I was wondering if the request and/or response size is something available under traefik /metrics, either by default or via some other configuration flag?

I know request and response size is accessible via an access logs logging stack (i.e. elastic + kibana) but I was hoping there might be a way for prometheus to scrape that info as well - and then I could just include that in my traefik dashboards on grafana!

Any input about this would be greatly appreciated! Thank you!
