Performance Schema status_by_thread Table

The session_status table is available from MariaDB 10.5.2.

The status_by_thread table contains status variable information about active foreground threads. The table does not collect statistics for Com_xxx variables.

The table contains the following columns:

Column	Description
THREAD_ID	The thread identifier of the session in which the status variable is defined.
VARIABLE_NAME	Status variable name.
VARIABLE_VALUE	Aggregated status variable value.

If TRUNCATE TABLE is run, will aggregate the status for all threads to the global status and account status, then reset the thread status. If account statistics are not collected but host and user status are, the session status is added to host and user status.
