MySQL Database: Maximum connection usage since startup
|Distribution: ||official part of Check_MK|
|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 plugin mk_mysql to be installed.
Further details about this plugin and monitoring of MySQL can be
found in the Check_MK online documentation in the article
"Monitoring MySQL with Check_MK".
On each host where the agent plugin mk_mysql is being installed
and the MySQL daemon is running one service per instance is being generated.
