Re: TOP Process on CPU/Memory

Hi,

1. Use top -h and see the processes consuming the resources.
2. Use tool like Glance/gpm to see and sort the processes, glance will also give you the process details.
3. UNIX95=1 ps -e -o vsz,pid,ruser,args | sort -rn |head

Re: TOP Process on CPU/Memory

Hi,

If look at man TOP, this what describes memory and time taken

n: %MEM -- Memory usage (RES)
A task's currently used share of available physical memory.


l: TIME -- CPU Time
Total CPU time the task has used since it started. When 'Cumulative
mode' is On, each process is listed with the cpu time that it and
its dead children has used. You toggle 'Cumulative mode' with 'S',
which is a command-line option and an interactive command. See the
'S' interactive command for additional information regarding this
mode.

So looking at these two statistcis in TOP you can figure out whatever you are looking for.

1.How to find Top Process on CPU i.e greater than 100 mins of CPU time?
>> ps -ef|head -20|sort -rk8

so this would list you the process took maximum CPU time.

2.How to find top process on memory i.e greater than 100MB?
just check top RES
