Overall LGTM, but would it be a better idea to record tracing spans instead of logging? As we can have hierarchy in tracing, and also the exact start / end timestamp that makes it easier to search. To reduce the amount of tracing data, we can also do something that only reports slow requests so as to reduce the pressure on the metrics / log server.
