Need a list of top 10 CPU using processes (also top 10 memory hogs, separately)

thenomad · #1 (**permalink**) 09-02-2009

Okay, I am trying to come up with a multi-platform script to report top ten CPU and memory hog processes, which will be run by our enterprise monitoring application as an auto-action item when the CPU and Memory utilization gets reported as higher than a certain threshold

I use top on other platforms but on AIX, I was not able to find top, but only topas. Unfortunately topas do not have an option of running in batch mode. For instance, I can tell top to run for one count/iteration and wite the output to a file, which in turn can be beaten up using any text processors to display the output I desire. topas can't

I tried using the output of ps -ef |sort -n -k 7 but 7th field is returning wonky results on the output of ps -ef. SO this stopped being an option.

Is there any way to get an output from topas as one can get from top ? If yes, how ? I am also open to other suggestions than topas as the monitor. I also have nmon on these aix boxes if it can be used for this purpose.

Thanks for all suggestions in advance.

but Im no AIX specialist and waiting for my boss to send me follow some courses such as AW18FR...(and after AU73FR... I can always dream...)

Thank you.. The output will be sufficient for a quick and dirty peek at the CPU hogs.

my hpux solution:
top -d 1 -n 10 -f /tmp/file; tail -11 /tmp/file

my Linux (RHEL) solution:
top -b -n 1 | sed -e "1,6d" | head -11

fyi...

Forgot... the second code was for memory...

Hi,

for AIX I am using:

Displaying top CPU_consuming processes

Code:

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

Displaying top 10 memory-consuming processes

Code:

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

Displaying the process in order of real memory use

Code:

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

Displaying process in order of nice value

Code:

ps -eakl | sort -n +7

Displaying the process in order of I/O

Code:

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

Kind regards
zxmaus
