Did you try the suggestion made by minazk? That should also provide you with the command being run, the PID associated with it, and the user running it...

Data
Yes, I tried it but I got the following:
Code:
root@galaxy [~]# ps -ef | grep 'PID'
UID        PID  PPID  C STIME TTY          TIME CMD
root     13675 13138  0 12:54 pts/0    00:00:00 grep PID
root@galaxy [~]# ps -ef | grep '13514'
root     13736 13138  0 12:54 pts/0    00:00:00 grep 13514
root@galaxy [~]# ps -ef | grep 13514
root     13779 13138  0 12:54 pts/0    00:00:00 grep 13514
root@galaxy [~]# ps -ef | grep PID
UID        PID  PPID  C STIME TTY          TIME CMD
root     13904 13138  0 12:55 pts/0    00:00:00 grep PID

Always I got "root"!

Try this: ps -aux | grep 'PID'
Does that work for you?

Sorry, it didn't work.

Code:
root@galaxy [~]# ps -aux | grep '648'
nobody   30773  0.2  0.8 12196 8648 ?        S    01:51   2:43 [httpd]
nobody   30777  0.1  0.7 11532 7648 ?        S    01:51   2:00 [httpd]
root       722  0.0  0.0  1768  620 pts/0    S    23:29   0:00 grep 648
root@galaxy [~]# ps -aux | grep '4170'
mysql     4170  0.0  1.5 31004 16200 ?       S    Jun26   1:02 [mysqld]
root       888  0.0  0.0  1772  624 pts/0    S    23:30   0:00 grep 4170

Seems like it worked as you requested. The user id of PID 4170 is mysql..... that is what you asked for in your original post isn't it?

The user is mysql..... at this point you would look at the CPU or memory stats of each mysql (child or parent) process and see if a single process is causing high usage. Right?

Hi,

NO Smilie, I'm working on hosting server so I need to know which account do these processes.
I need to know the username (domain), not mySQL in general.

Thanks,
Khalid

And I just explained to you (as others have) how to do it......

Do you understand the concept of parent and child processes?


It seems that you don't understand the core concepts and the relationship between parent processes (like mysql) and the individual user processes that are mysql children.......
