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.
