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.
