1 title: MySQL Database: Maximum connection usage since startup
7 This check allows the tracking of connection usage for a MySQL database.
8 Therefore it queries the maximum number of connections that have been
9 in use simultaneously since the server started and
10 the maximum number of possible parallel connections.
11 From these both it calculates the
12 maximum usage level of these connections in percent
13 and matches the specified {WARN} and {CRIT} thresholds against it.
15 This check needs the agent plugin {mk_mysql} to be installed.
16 Further details about this plugin and monitoring of MySQL can be
17 found in the Check_MK online documentation in the article
18 "Monitoring MySQL with Check_MK".
21 On each host where the agent plugin {mk_mysql} is being installed
22 and the MySQL daemon is running one service per instance is being generated.
