Percona Toolkit is a collection of advanced command-line tools used by Percona) support staff to perform a variety of MySQL, MongoDB, and system tasks that are too difficult or complex to perform manually.
These tools are ideal alternatives to private or “one-off” scripts, because they are professionally developed, formally tested, and fully documented. They are also fully self-contained, so installation is quick and easy, and no libraries are installed.
Percona Toolkit was derived from Maatkit and Aspersa, two of the best-known toolkits for MySQL server administration. It is developed and supported by Percona. For more information and other free, open-source software developed by Percona, visit http://www.percona.com/software/.
