The newton version of the JSONFormatter adds all of the values from the
context to the log record:


That should include the request_id.

Which service's logs are missing the request_id?

Chaining request_id values from one service to the next was a separate
piece of work, and I don't remember off the top of my head when that was
added. Perhaps someone else can. I think Sean Dague drove a lot of that
