Finding Process id which is taking maxm. load 1

[samirm]

Hi AIX guru,

All of a sudden in one of my production server the uptime is showing as follows :-

10:09AM up 16 days, 7:58, 106 users, load average: 13.33, 7.09, 6.10

Is there any way I can find out the particular process which is making this much load in the system ?

ps aux

http://www will

work ?

top or topas

sam@nodeA: /home/sam > topas
topas: Unable to initialize Spmi interface
Spmi: Error 13 opening /dev/mem


Can't we get from "ps" command ? I can't remember at this time, but there were some combination of flag which used to return the load with respect to process details from maxm. to minm.

Can you run topas as root - that's the problem there.

I don't mind people who aren't what they seem. I just wish they'd make their mind up.

Thanks Alan ..

I did silly thing by executing the topas without root.
I am getting the details ..now

...No probs.

*Thinks* I really must change my sig!!

ps aux

another possible command to be used!

and there are plenty of things you can do if you read this manual

Thanks Khalid,

For this wonderful link. I was exactly looking for the ps commands with desired flags instead of going for topas.

You can use variants of this, which I have set as a function:

ps auxw|egrep -v "^USER"|sort -n +4

Larger users at the bottom. Keeps down the eyestrain. Note that this is inaccurate when dealing with shared mem. Also note that I am not really a performance guy. Anther fun thing is 'svmon -P'.

To run topas with a non root user you need to set read permission to /dev/mem
Att.: You need to add the permission, not to remove the existent permission.

Hi

Following the ps commands i have collected

1) Displaying top CPU_consuming processes:

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

2) Displaying top 10 memory-sonsuming 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) 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 <PID>


Hope this helps
