mariadb-dumpslow

Previously, the client was called mysqldumpslow. It can still be accessed under this name, via a symlink in Linux, or an alternate binary in Windows.

mariadb-dumpslow is a tool to examine the slow query log.

It parses the slow query log files, printing a summary result. Normally, mariadb-dumpslow 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.
