Threads_connected

USAGE

DETAILS

The Threads_connected status variable shows the number of client connections currently connected.

Interaction with Thread Pool

When thread_handling=pool-of-threads is set, the Threads_connected status variable's value does not reflect the actual number of threads, because the client connections would share threads from the thread pool.

EXAMPLES

Show Value with SHOW STATUS

SHOW GLOBAL STATUS statement can show the global value:

SHOW GLOBAL STATUS
   LIKE 'Threads_connected';

Since this status variable is only global scope, SHOW STATUS and SHOW SESSION STATUS also show the global value.

Information Schema

The information_schema.GLOBAL_STATUS table can be queried to obtain the global value:

SELECT *
FROM information_schema.GLOBAL_STATUS
WHERE VARIABLE_NAME LIKE 'Threads_connected';

This status variable is only global scope, so the information_schema.SESSION_STATUS table can also be queried to obtain the global value:

SELECT *
FROM information_schema.SESSION_STATUS
WHERE VARIABLE_NAME LIKE 'Threads_connected';
