Hello,

I’d be interested in various examples of basic monitoring in the context of a handler on a web server built with Bandit and Plug.

Basically, I’m building a mini blog as a side project to learn Elixir, and I’m wondering how I could add a functionality that times how long it took from the reception of a request by the server until the response is sent, and logs it.

I currently just have the following super basic handler:

get "/" do
    conn
    |> put_resp_content_type("text/html")
    |> send_file(200, "index.html")
  end

how do I measure and log execution time for it?
