You could enable MySQL's general query logging to a table (note that this has a non-negligible performance impact) and then perform queries on the data:

SELECT   DATE(event_time), HOUR(event_time), COUNT(*) AS select_queries
FROM     mysql.general_log
WHERE    argument LIKE 'select %'
GROUP BY DATE(event_time), HOUR(event_time)
