NAME
Sys::Statistics::Linux::ProcStats - Collect linux process statistics.SYNOPSIS
use Sys::Statistics::Linux::ProcStats; my $lxs = Sys::Statistics::Linux::ProcStats->new; $lxs->init; sleep 1; my $stat = $lxs->get;
Or
my $lxs = Sys::Statistics::Linux::ProcStats->new(initfile => $file); $lxs->init; my $stat = $lxs->get;
DESCRIPTION
Sys::Statistics::Linux::ProcStats gathers process statistics from the virtual /proc filesystem (procfs).For more information read the documentation of the front-end module Sys::Statistics::Linux.
IMPORTANT
I renamed key "procs_blocked" to "blocked"!LOAD AVERAGE STATISTICS
Generated by /proc/stat and /proc/loadavg.new - Number of new processes that were produced per second. runqueue - The number of currently executing kernel scheduling entities (processes, threads). count - The number of kernel scheduling entities that currently exist on the system (processes, threads). blocked - Number of processes blocked waiting for I/O to complete (Linux 2.5.45 onwards). running - Number of processes in runnable state (Linux 2.5.45 onwards).
METHODS
new()
Call "new()" to create a new object.my $lxs = Sys::Statistics::Linux::ProcStats->new;
Maybe you want to store/load the initial statistics to/from a file:
my $lxs = Sys::Statistics::Linux::ProcStats->new(initfile => '/tmp/procstats.yml');
If you set "initfile" it's not necessary to call sleep before "get()".
init()
Call "init()" to initialize the statistics.$lxs->init;
get()
Call "get()" to get the statistics. "get()" returns the statistics as a hash reference.my $stat = $lxs->get;
