SHOW STATUS [LIKE 'pattern']

SHOW STATUS provides server status information. This information also can be obtained using the mysqladmin extended-status command. This statement does not require any privilege. It requires only the ability to connect to the server.

Partial output is shown here. The list of names and values may be different for your server. The meaning of each variable is given in Section 5.1.5, “Server Status Variables”.
