AIX:Performance commands

1) Displaying top CPU_consuming processes:

ps aux | head -1; ps aux | sort -rn +2 | head -10

2) Displaying top 10 memory-consuming processes:

ps aux | head -1; ps aux | sort -rn +3 | head

3) Displaying process in order of being penalized:

ps -eakl | head -1; ps -eakl | sort -rn +5

4) Displaying process in order of priority:

ps -eakl | sort -n +6 | head                                                                                            

5) Displaying process in order of nice value

ps -eakl | sort -n +7

6) Displaying the process in order of time

ps vx | head -1;ps vx | grep -v PID | sort -rn +3 | head -10

7) Displaying the process in order of real memory use

ps vx | head -1; ps vx | grep -v PID | sort -rn +6 | head -10

8) Displaying the process in order of I/O

ps vx | head -1; ps vx | grep -v PID | sort -rn +4 | head -10

9) Displaying WLM classes

ps -a -o pid, user, class, pcpu, pmem, args

10) Determining process ID of wait processes:

ps vg | head -1; ps vg | grep -w wait

11) Wait process bound to CPU

ps -mo THREAD -p <PID>

12) CPU usage with priority levels
#topas -P

13) Processes using the most paging space
svmon -gP -t 3 |grep -p Pid|grep '^.*[0-9]'

14) Top memory consuming processes
svmon -Put 5
