Top memory consuming processes

You can check for top memory consuming processes by issuing the following commands:

we use the following ps commands in order to check for performance probelms

1) Displaying top CPU_consuming processes: 


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

2) Displaying top 10 memory-consuming processes:

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

3) Displaying process in order of being penalized:

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

4) Displaying process in order of priority:

ps -eakl | sort -n  | head

5) Displaying process in order of nice value

ps -eakl | sort -n

6) Displaying the process in order of time

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

7) Displaying the process in order of real memory use

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

8) Displaying the process in order of I/O

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

9) Displaying WLM classes

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

10) Determinimg process ID of wait processes:

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

11) Wait process bound to CPU

ps -mo THREAD -p
