Performance Schema users Table
Description
Each user that connects to the server is stored as a row in the users table, along with current and total connections.
The table size is determined at startup by the value of the performance_schema_users_size system variable. If this is set to 0, user statistics will be disabled.
| Column | Description |
|---|---|
USER | The connection's client user name for the connection, or NULL if an internal thread. |
CURRENT_CONNECTIONS | Current connections for the user. |
TOTAL_CONNECTIONS | Total connections for the user. |
Example
