Here is a line from the Heroku from their docs:

2010-09-16T15:13:46.723498+00:00 heroku[router]: at=info method=GET path="/posts" host=myapp.herokuapp.com" fwd="204.204.204.204" dyno=web.1 connect=1ms service=18ms status=200 bytes=975

And an endpoint is a line that looks like this:

GET /api/users/{user_id}/count_pending_messages

I wrote this together for a test I'm doing. What I'm mainly interested is if this code follow common best practices and if there are any improvements I can make in terms of memory efficiency.
