+=head1 NAME
+
+mysql_ - Munin plugin to display misc MySQL server status
+
+=head1 APPLICABLE SYSTEMS
+
+Any MySQL platform, tested by the authors on:
+* MySQL 5.6.12
+* MySQL 5.5.32, 5.5.37
+* MySQL 5.1.29,
+* MySQL 5.0.51
+* MariaDB 5.5.39
+* MariaDB-5.5.39(galera).
+
+Plugins:
+* MariaDB-10 Query Response Time: https://mariadb.com/kb/en/mariadb/query_response_time-plugin/
+
+Information Schema tables:
+* User statistics - MariaDB-5.2+, OurDelta, Percona Server - https://mariadb.com/kb/en/mariadb/user-statistics
+
+=head1 CONFIGURATION
+
+This script is used to generate data for several graphs. To generate
+data for one specific graph, you need to create a symbolic link with a
+name like mysql_<GRAPH> to this script.
+
+If you need to run against multiple MySQL instances on the same host,
+create your symlinks with names like mysql<N>_<GRAPH> where N is any
+non-negative integer. You must also set the env.cachenamespace variable
+to a unique value for each group of symlinks.
+
+To get a list of symlinks that can be created, run:
+
+ ./mysql_ suggest
+
+In addition you might need to specify connection parameters in the
+plugin configuration to override the defaults. These are the defaults:
+
+ [mysql_*]
+ env.mysqlconnection DBI:mysql:information_schema
+ env.mysqluser root
+
+Non-default example:
+
+ [mysql_*]
+ env.mysqlconnection DBI:mysql:information_schema;host=127.0.0.1;port=3306
+ env.mysqluser munin
+ env.mysqlpassword geheim
+ env.cachenamespace munin_mysql_pri
+ [mysql2_*]
+ env.mysqlconnection DBI:mysql:information_schema;host=127.0.0.1;port=13306
+ env.mysqluser munin;
+ env.mysqlpassword ryuWyawEv
+ env.cachenamespace munin_mysql_alt
+ [mysql10_*]
+ user munin
+ env.mysqluser munin
+ env.mysqlconnection DBI:mysql:information_schema;mysql_read_default_file=/etc/munin/.my-10.cnf
+ env.cachenamespace munin_mysql_10
+ # here the [client] section of /etc/munin/.my-10.cnf is read. socket= can
+ # be specified here.
+
+Creating a munin user:
+
+ CREATE USER 'munin'@'localhost' IDENTIFIED BY 'ryuWyawEv';
+
+or with a unix_socket plugin (INSTALL PLUGIN unix_socket SONAME 'auth_socket')
+
+ CREATE USER 'munin'@'localhost' IDENTIFIED WITH unix_socket;
+
+Note: requires 'user munin' in the configuration.
+
+The minimum required priviledges of the munin database user is:
+
+ GRANT PROCESS, REPLICATION CLIENT ON *.* TO 'munin'@'localhost';
+
+
+Warning and critical values can be set via the environment in the usual way.
+For example:
+
+ [mysql_replication]
+ env.slave_io_running_warning 0.5
+ env.slave_sql_running_warning 0.5
+ env.seconds_behind_master_warning 300
+ env.seconds_behind_master_critical 600
+
+=head1 DEPENDENCIES
+
+=over
+
+=item Cache::Cache
+
+The plugin uses shared memory to cache the statistics gathered from
+MySQL. This ensures minimal inpact on the MySQL server.
+
+=item DBD::mysql
+
+=back
+
+=head1 INTERPRETATION
+
+=head2 InnoDB
+
+The statistics from innodb are mainly collected from the command
+
+ SHOW ENGINE INNODB STATUS
+
+A nice walk through is found at
+L<http://www.mysqlperformanceblog.com/2006/07/17/show-innodb-status-walk-through/>
+
+Undo logs:
+L<http://blog.jcole.us/2014/04/16/the-basics-of-the-innodb-undo-logging-and-history-system/>
+
+=head2 The graphs
+
+FIX point to relevant sections in the MySQL manual and other www
+resources for each graph
+
+=over
+
+=item mysql_replication
+
+slave_io_running and slave_sql_running both translate the "Yes" values to 0 and
+anything else to 1 for their respective fields in the "SHOW SLAVE STATUS" output.
+This can be used to warn on slave failure if the warning and critical values
+are set as seen in a previous section.
+
+=item wsrep_cluster_status
+
+"Primary" is translated 0 and "non-Primary" to 1.
