SHOW STATUS
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. With
SESSION, it displays the status values
for the current connection. If no modifier is present, the default is
SESSION. LOCAL is a synonym for
SESSION. 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.
