MySQL database server counter reference

Posted: April 21st, 2008 | Author: TnT Admin | Filed under: Concepts | Tags: | No Comments »

These are the counters provided by running show status command in MySQL (as of this writing, I’m writing based on MySQL 6.0). It will be the same command to retrieve statistics as mentioned in “How-to configure MySQL database monitoring” which you can refer back again to for concept and configuration details. I’ve list down the counters for your convenience at first glance if you are looking for what to monitor in MySQL. I believed that you can agree with me that we are not experts in MySQL during load test projects.

Anyway, the definition of the counters can be found in “MySQL 6.0 Reference Manual :: 5 MySQL Server Administration :: 5.1 The MySQL Server :: 5.1.5 Status Variables” which you should refer to when in doubt.
