Question

With administrative permissions im mysql, how can I see all the open connections to a specific db in my server?

This is what the MySQL Workbench does.

That should do the trick for the newest MySQL versions:

SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST WHERE DB = "elstream_development";

Answer 4

In MySql,the following query shall show the total number of open connections:

show status like 'Threads_connected';

Answer 5

If you're running a *nix system, also consider mytop.

To limit the results to one database, press "d" when it's running then type in the database name.

Answer 6

The command is

SHOW PROCESSLIST

Unfortunately, it has no narrowing parameters. If you need them you can do it from the command line:

mysqladmin processlist | grep database-name
