Please explain cleary meaning of monitoring. Do you want to capture CPU and Memory usage during certain period or capture data and recompile it later?

Glance and top commands will help you to monitor system activity.

Hi IT_2007, I don't want to collect the information about cpu or memory usage in a period of time. I need a snapshot to determine which is the process (only one) using more cpu or memory...and then kill it.

Hi Frank,

pid of process consuming most CPU displayed on stdout:
# UNIX95= ps -e -o "pcpu,pid" | sort -n -k1 | tail -1 | awk '{print $2}'

pid of process consuming most memory displayed on stdout:
# UNIX95= ps -e -o "vsz,pid" | sort -n -k1 | tail -1 | awk '{print $2}'

Hi Frank,

Setting UNIX95 enables XPG4 behavior for a command, which typically adds extra functionality. In the case of 'ps', XPG4 behavior allows extra columns to be specified. Remember to never export UNIX95 to your environment, as it will cause unexpected behavior in certain commands.
