Customizing ps command

Shell Programming and Scripting

Hi,
I want to monitor our batch jobs at a specific interval for later analysis to see the performance and CPU utilization

USER       PID %CPU %MEM    VSZ   RSS TTY      STAT START   TIME COMMAND
 ps aux|grep dsadm|head
xxxxx   386  0.0  0.0 103524 15448 pts/0    S    Mar27   0:00 /etrade/home/dsadm/sqllib/bin/db2bp 28075A14861 5 A

From which i can later identify the CPU and memory utilization etc.
But couldnt figure out a way to print the parent id in this output

ps -eo command,user,pid,ppid

i have this command to get the parent id also. but here i cant display the any of the performance parameter's. Is there a way to print both PID hierarchy and various performance factors for each process

What is your OS and version?

Try:

ps axo user,pid,ppid,pcpu,%mem,vsz,rss,tt,stat,start,time,command

Thanks a ton
Thats what i was looking for..
Just needed a small modification to display the entire command

ps -eo cmd:200,user,pid,ppid,pcpu,pmem,vsz,rss,start,stat

Can i Give a separator between the fields in ps command itself

 ps -eo user,pid,ppid,pcpu,pmem,vsz,rss,start,stat,cmd|grep DW_DCM|head

I tried using awk command but if the 'command field' has space then output is weird.
