Size of MySQL tablespaces

Distribution: official part of Check_MK
License: GPL
Supported Agents: Linux

This check verifies the space used by MySQL databases as returned from MySQL. The information is built by summing up the space for indices and tables of a given database.

It relies on the information returned from MySQL, which can be incorrect as MySQL does not always account for all database information.

In practice, the check works well for InnoDB. This should even include InnoDB on raw partitions.

MyISAM reporting is not possible as MySQL does not make the data available. (See the dirsize checks as a workaround should you really use MyISAM)

The check will go to WARN or CRIT levels if a user-specified limit is exceeded.

Discovery

The check generates one item per Database found. Internal MySQL databases are ignored.
