Hello All,
I need to write a program that would monitor the unix processes and gives the report for each process like start time, mem usage, including all child process details and so on. I just want to know does any of the existing open source project does this already. I am looking into strace/ps command which is useful for me to get process details. Instead of me analyzing proc file system, I think there must be some basic unix utility does this. I prefer simple monitoring utility instead of complex monitoring tools. Please share your ideas with me.
Thanks.

top, time, mpstat, gnome-system-monitor, ipcs, procinfo, oprofile, vmstat, slabtop, sar. I wonder how many profiling tools I missed.

Thanks for the tools specified.
