When I check the metrics that Traefik v2 exposes I see
What do these metrics actually measure?
traefik_entrypoint_request_duration_seconds: Does it measure the duration from the start of the requests, through all middlewares up to the upstream service and back? which means that the traefik_service_request_duration_seconds metric included in this one?
traefik_service_request_duration_seconds: is only the duration for the requests to the upstream service and back withouth anything in between?
