MySQL: Maximum Connection Usage since Startup

Distribution	Official part of Checkmk
License	GPLv2
Supported Agents	Linux

This check allows the tracking of connection usage for a MySQL database. Therefore it queries the maximum number of connections that have been in use simultaneously since the server started and the maximum number of possible parallel connections. From these both it calculates the maximum usage level of these connections in percent and matches the specified WARN and CRIT thresholds against it.

This check needs the agent plug-in mk_mysql to be installed. Further details about this plug-in and monitoring of MySQL can be found in the Checkmk online documentation in the article "Monitoring MySQL with Checkmk".
