[Tutor] CPU Utilization

[Hugo González Monteverde]

Hi,

top is very interactive so it would not be easy at all to parse.

I can suggest reading /proc/loadavg if you're in Linux.

proc(5) ('man 5 proc') says that /proc/loadavg is
     The load average numbers give the number of jobs in
     the run queue averaged over 1, 5 and 15 minutes.
     They are the same as the load average numbers given
     by uptime(1) and other programs.

It can be easily parsed with split()

Hope that helps,

Hugo
