SHOW USER_STATISTICS
MariaDB starting with 5.2
MariaDB 5.2 introduced the User Statistics feature.
Syntax
SHOW USER_STATISTICS
Description
The SHOW USER_STATISTICS
statement was introduced in MariaDB 5.2 as part of the User Statistics feature. It was removed as a separate statement in MariaDB 10.1.1, but effectively replaced by the generic SHOW information_schema_table
statement. The information_schema.USER_STATISTICS
table holds statistics about user activity. You can use this table to find out such things as which user is causing the most load and which users are being abusive. You can also use this table to measure how close to capacity the server may be.
The userstat
system variable must be set to 1 to activate this feature. See the User Statistics and information_schema.USER_STATISTICS
table for more information.
