NAME
Sys::Statistics::Linux::CpuStats - Collect linux cpu statistics.
SYNOPSIS
use Sys::Statistics::Linux::CpuStats;
my $lxs = new Sys::Statistics::Linux::CpuStats;
$lxs->init;
sleep 1;
my $stats = $lxs->get;DESCRIPTION
Sys::Statistics::Linux::CpuStats gathers cpu statistics from the virtual /proc filesystem (procfs).
For more informations read the documentation of the front-end module Sys::Statistics::Linux.
CPU STATISTICS
Generated by /proc/stat for each cpu (cpu0, cpu1 ...). cpu without a number is the summary.
user - Percentage of CPU utilization at the user level.
nice - Percentage of CPU utilization at the user level with nice priority.
system - Percentage of CPU utilization at the system level.
idle - Percentage of time the CPU is in idle state.
iowait - Percentage of time the CPU is in idle state because an i/o operation is waiting for a disk.
This statistic is only available by kernel versions higher than 2.4. Otherwise this statistic
exists but will be ever 0.
total - Total percentage of CPU utilization (user + nice + system).METHODS
