ps command

ps command gives the cputime for a process.

Is there a way to find the time spent by a process in IO?
and also time spent on network (process level)?

Thanks in advance.

You can break up a process CPU time into user time and system time by looking at the /proc/PID/stat file. The 14th and 15th fields are the user time and kernel time in jiffies (typically 1/100th or 1/250th of a second, depending on your kernel).

For finer grained monitoring of system access, you can use /usr/bin/time -v application to give detail, or strace -c application to monitor all the system calls.

Thanks my friend. That is a good info to start.
