See if there are peak times for error/warning/info messages

[laurenassour]

Some heuristics on when we get the most types of messages might be interesting/useful in cleaning up noisy logging or finding temporal problems.

Just to clarify, this means that we should find peak time ranges for each type of message (error, warning, info) separately, correct?
