mysqldumpslow is a tool to examine the #slow_query_log.
It parses the slow query log files, printing a summary result. Normally, mysqldumpslow groups queries that are similar except for the particular values of number and string data values. It “abstracts” these values to N and ´S´ when displaying summary output. The -a and -n options can be used to modify value abstracting behavior.
