MySQL status in terms of active or total connections?

The active or total connection can be known with the help of threads_connected variable. The variable tells about the number of currently open connections.

The query is as follows −

mysql> show status where `variable_name` = 'Threads_connected';

Here is the output.

+-------------------+-------+
| Variable_name     | Value |
+-------------------+-------+
| Threads_connected | 1     |
+-------------------+-------+
1 row in set (0.06 sec)

We can check the same with the help of show command. The query is as follows −

mysql> show processlist;

Here is the output.

+----+-----------------+-----------------+----------+---------+--------+------------------------+------------------+
| Id | User            | Host            | db       | Command | Time   | State                  | Info             |
+----+-----------------+-----------------+----------+---------+--------+------------------------+------------------+
|  4 | event_scheduler | localhost       | NULL     | Daemon  | 349012 | Waiting on empty queue | NULL             |
| 11 | root            | localhost:54746 | business | Query   |      1 | starting               | show processlist |
+----+-----------------+-----------------+----------+---------+--------+------------------------+------------------+
2 rows in set (0.31 sec)
