[Solved] Customizing ps command

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

Code:

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

Code:

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

atd

ATD(8)							      System Manager's Manual							    ATD(8)

NAME

       atd - run jobs queued for later execution

SYNOPSIS

       atd [-l load_avg] [-b batch_interval] [-d] [-f] [-s]

DESCRIPTION

       atd runs jobs queued by at(1).

OPTIONS

       -l      Specifies  a  limiting load factor, over which batch jobs should not be run, instead of the compile-time choice of 0.8.	For an SMP
	       system with n CPUs, you will probably want to set this higher than n-1.

       -b      Specify the minimum interval in seconds between the start of two batch jobs (60 default).

       -d      Debug; print error messages to standard error instead of using syslog(3).  This option also implies -f.

       -f      Run atd in the foreground.

       -s      Process the at/batch queue only once.  This is primarily of use for compatibility with old versions of at; atd -s is equivalent	to
	       the old atrun command.

WARNING

       atd won't work if its spool directory is mounted via NFS even if no_root_squash is set.

FILES

       /var/spool/at The directory for storing jobs; this should be mode 700, owner root.

       /var/spool/at/spool The directory for storing output; this should be mode 700, owner root.

       /etc/at.allow, /etc/at.deny determine who can use the at system.

SEE ALSO

       at(1), at.deny(5), at.allow(5), cron(8), crontab(1), syslog(3).

BUGS

       The functionality of atd should be merged into cron(8).
