SHOW STATUS

View server status variables. This statement displays counters and metrics for server activity, performance, and health.

Syntax

SHOW [GLOBAL | SESSION] STATUS
    [LIKE 'pattern' | WHERE expr]

Description

SHOW STATUS provides server status information. This information also can be obtained using the mariadb-admin extended-status command, or by querying the Information Schema GLOBAL_STATUS and SESSION_STATUS tables. The LIKE clause, if present, indicates which variable names to match. The WHERE clause can be given to select rows using more general conditions.

With the GLOBAL modifier, SHOW STATUS displays the status values for all connections to MariaDB. WithSESSION, it displays the status values for the current connection. If no modifier is present, the default isSESSION. LOCAL is a synonym forSESSION. If you see a lot of 0 values, the reason is probably that you have used SHOW STATUS with a new connection instead of SHOW GLOBAL STATUS.

Some status variables have only a global value. For these, you get the same value for both GLOBAL and SESSION.

See Server Status Variables for a full list, scope and description of the variables that can be viewed with SHOW STATUS.

The LIKE clause, if present on its own, indicates which variable name to match.

The WHERE and LIKE clauses can be given to select rows using more general conditions, as discussed in Extended SHOW.
