Is there some way in Phoenix to see what path was used to match a route?
This would be very useful for metrics and logging (and probably other things). We would like to have the match path as a label in prometheus and as a log field so we can aggregate on that in kibana.
In Plug this was added a while ago in this PR Add router path to Plug.Conn by mgartner · Pull Request #630 · elixir-plug/plug · GitHub
I’ve check that there are no equivalent field in conn.private from Phoenix, but is it accessible in some other way?

What version of plug are you using according to mix.exs and mix.lock?
NobbZ
In general that field should only get accessed through
Plug.Router.match_path, which is available since 1.5 as far as I can tell.fredr
Plug is version
1.7.1, but I don’t think the Phoenix.Router uses the Plug.Router to match under the hood.It works fine in a regular Plug.Router outside of Phoenix.

I always thought
Phoenix.Routerwhere just wrappingPlug.Router.
