MySQL InnoDB engine IO statistics

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

This check tracks the IO rate of the InnoDB database engine for MySQL. The data is gathered from the show global status query.

It allows you plan IO device capacity by seeing how much is read and written by InnoDB, or to proactively generate alerts if something is generating far too much write IO. The configuration of this check is internally done as a "disk check" but presented in as an application monitoring in WATO.

The check is configured like the diskstat check for block devices.


The check generates one item per instance, representing the InnoDB writers for a MySQL Daemon.
