Performance Schema accounts Table

Description

Each account that connects to the server is stored as a row in the accounts table, along with current and total connections.

The table size is determined at startup by the value of the performance_schema_accounts_size system variable. If this is set to 0, account statistics will be disabled.

The USER and HOST values shown here are the username and host used for user connections, not the patterns used to check permissions.

Example

SELECT * FROM performance_schema.accounts;
+------------------+-----------+---------------------+-------------------+
| USER             | HOST      | CURRENT_CONNECTIONS | TOTAL_CONNECTIONS |
+------------------+-----------+---------------------+-------------------+
| root             | localhost |                   1 |                 2 |
| NULL             | NULL      |                  20 |                23 |
| debian-sys-maint | localhost |                   0 |                35 |
