NAME
Sys::Statistics::Linux::CpuStats - Collect linux cpu statistics.
SYNOPSIS
use Sys::Statistics::Linux::CpuStats;
my $lxs = Sys::Statistics::Linux::CpuStats->new;
$lxs->init;
sleep 1;
my $stats = $lxs->get;
Or
my $lxs = Sys::Statistics::Linux::CpuStats->new(initfile => $file);
$lxs->init;
my $stats = $lxs->get;
DESCRIPTION
Sys::Statistics::Linux::CpuStats gathers cpu statistics from the virtual /proc filesystem (procfs).
For more information 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.
total - Total percentage of CPU utilization.
Statistics with kernels >= 2.6.
iowait - Percentage of time the CPU is in idle state because an I/O operation
is waiting to complete.
irq - Percentage of time the CPU is servicing interrupts.
softirq - Percentage of time the CPU is servicing softirqs.
steal - Percentage of stolen CPU time, which is the time spent in other
operating systems when running in a virtualized environment (>=2.6.11).
METHODS
new()
Call "new()" to create a new object.
my $lxs = Sys::Statistics::Linux::CpuStats->new;
Maybe you want to store/load the initial statistics to/from a file:
my $lxs = Sys::Statistics::Linux::CpuStats->new(initfile => '/tmp/cpustats.yml');
If you set "initfile" it's not necessary to call sleep before "get()".
It's also possible to set the path to the proc filesystem.
Sys::Statistics::Linux::CpuStats->new(
files => {
# This is the default
path => '/proc'
stat => 'stat',
}
);
init()
Call "init()" to initialize the statistics.
$lxs->init;
get()
Call "get()" to get the statistics. "get()" returns the statistics as a hash reference.
my $stats = $lxs->get;
raw()
Get raw values.
