Syntax
------ 
SHOW [GLOBAL | SESSION] STATUS
 [LIKE 'pattern' | WHERE expr]
 
Description
----------- 
SHOW STATUS provides server status information. This
information also can be obtained using the mysqladmin
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.
