check_mysql_counters

check_mysql_counters is a nagios plugin and pnp4nagios template designed to show you performance trends in your MySQL servers.

To use, copy check_mysql_counters to your nagios libexec directory if you are using MySQL 5.1, check_mysql_counters_55 if you are using MySQL 5.5, check_mysql_counters_56 if you are using MySQL 5.6, check_mysql_counters_p55 if you are using Percona 5.5, or check_mysql_counters_p56 if you are using Percona 5.6

Then create a MYSQL_COUNTERS nagios service that executes the plugin:

• CentOS6 MySQL 5.1 (mysql-server package): check_mysql_counters -H host -P port -u mysqluser -p mysqlpassword
• Oracle 5.1: check_mysql_counters -H host -P port -u mysqluser -p mysqlpassword
• Oracle 5.5: check_mysql_counters_55 -H host -P port -u mysqluser -p mysqlpassword
• Oracle 5.6: check_mysql_counters_56 -H host -P port -u mysqluser -p mysqlpassword
• Percona 5.5: check_mysql_counters_p55 -H host -P port -u mysqluser -p mysqlpassword
• Percona 5.6: check_mysql_counters_p56 -H host -P port -u mysqluser -p mysqlpassword

Then copy the correct check_mysql_counters.php template from the directory

• centos_5_1_mysql_5_1
• oracle_5_1_with_innodb_plugin
• oracle_5_1_without_innodb_plugin
• oracle_5_5
• oracle_5_6
• percona_5_5
• percona_5_6

to your pnp4nagios template directory - the default location is /usr/local/pnp4nagios/share/templates

The plugin currently does not support being called by NRPE (the data returned is too large), a future version might address this.
