MySQL: Capacity

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.


Name of the instance and name of the database seperated by a colon ({:})


One service is created for each database. Internal MySQL databases are ignored.
