By the way, every utility is not for everyone. Its only for those who actually needed. :)

Imagine your production server is busy, server will spend most of it’s resources in writing to general log `TABLE` itself which in turn can reduce performance drastically.

@Rob Smith
I agreed that a DBA not only want to see queries logged in between specific time but also how many queries are repeating, query pattern, filter based on MySQL user etc.. can be useful.
I am using MONyog which can read log (slow and general) from `FILE` as well as `TABLE` and gives me aggregated result-set using which I can easily determine problematic queries.
I am not saying not to use pt-query-digest but for those who likes GUI for them it’s worth trying.
