Hi all,
I'm using python and psutil a library to get system informations like cpu usage (percent) for a given process.
My question is if I have the value in % of the cpu usage how I could get the cpu usage in cycle number I mean not in percent?

PMCCONTROL(8) BSD System Manager's Manual PMCCONTROL(8)
NAME
pmccontrol -- control hardware performance monitoring counters
SYNOPSIS
pmccontrol [-c cpu | -d pmc | -e pmc] ...
pmccontrol -l
pmccontrol -L
pmccontrol -s
DESCRIPTION
The pmccontrol utility controls the operation of the system's hardware performance monitoring counters.
OPTIONS
The pmccontrol utility processes options in command line order, so later options modify the effect of earlier ones. The following options
are available:
-c cpu Subsequent enable and disable options affect the CPU denoted by argument cpu. The argument cpu is a number denoting a CPU in the
system, or ``*'', denoting all unhalted CPUs in the system.
-d pmc Disable PMC number pmc on the CPU specified by -c, preventing it from being used till subsequently re-enabled. The argument pmc is a
number denoting a specific PMC, or ``*'' denoting all the PMCs on the specified CPU.
Only idle PMCs may be disabled.
-e pmc Enable PMC number pmc, on the CPU specified by -c, allowing it to be used in the future. The argument pmc is a number denoting a
specific PMC, or ``*'' denoting all the PMCs on the specified CPU. If PMC pmc is already enabled, this option has no effect.
-l List available hardware performance counters and their current disposition.
-L List available hardware performance counter classes and their supported event names.
-s Print driver statistics maintained by hwpmc(4).
EXAMPLES
To disable all PMCs on all CPUs, use the command:
pmccontrol -d*
To enable all PMCs on all CPUs, use:
pmccontrol -e*
To disable PMCs 0 and 1 on CPU 2, use:
pmccontrol -c2 -d0 -d1
To disable PMC 0 of CPU 0 only, and enable all other PMCS on all other CPUs, use:
pmccontrol -c* -e* -c0 -d0
DIAGNOSTICS
The pmccontrol utility exits 0 on success, and >0 if an error occurs.
SEE ALSO
pmc(3), pmclog(3), hwpmc(4), pmcstat(8), sysctl(8)
HISTORY
The pmccontrol utility first appeared in FreeBSD 6.0.
