CPU and Memory Utilization of Processes on AIX environment

You may use the following commands for checking CPU/Memory utilization.

Displaying top CPU_consuming processes:
#ps aux | head -1; ps aux | sort -rn +2 | head -10

Displaying top 10 memory-consuming processes:
#ps aux | head -1; ps aux | sort -rn +3 | head

Displaying process in order of being penalized:
#ps -eakl | head -1; ps -eakl | sort -rn +5

Displaying process in order of priority:
#ps -eakl | sort -n +6 | head

Displaying process in order of nice value
#ps -eakl | sort -n +7

Displaying the process in order of time
#ps vx | head -1;ps vx | grep -v PID | sort -rn +3 | head -10

Displaying the process in order of real memory use
#ps vx | head -1; ps vx | grep -v PID | sort -rn +6 | head -10

Displaying the process in order of I/O
#ps vx | head -1; ps vx | grep -v PID | sort -rn +4 | head -10

Displaying WLM classes
#ps -a -o pid, user, class, pcpu, pmem, args

Determinimg process ID of wait processes:
#ps vg | head -1; ps vg | grep -w wait

Wait process bound to CPU
#ps -mo THREAD -p <PID>

Cpu usage with priority levels
#topas -P
