To get the database server status run this query in either the SQL window of your preferred interface (PHPMyAdmin or other) or on the MySQL CLI interface.
SHOW STATUS;
You can specify whether you wish to receive the SESSION or GLOBAL status of your sever like so: Session status:
SHOW SESSION STATUS;
Global status:
SHOW GLOBAL STATUS;
Like any other SQL command you can add parameters to your query such as the LIKE command:
SHOW [GLOBAL | SESSION] STATUS LIKE 'Key%';
Or the Where command:
SHOW [GLOBAL | SESSION] STATUS WHERE VALUE > 0;
The main difference between GLOBAL and SESSION is that with the GLOBAL modifier the command displays aggregated information about the server and all of it's connections, while the SESSION modifier will only show the values for the current connection.
