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()".

It's also possible to set the path to the proc filesystem.

     Sys::Statistics::Linux::ProcStats->new(
        files => {
            # This is the default
            path    => '/proc',
            loadavg => 'loadavg',
            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 $stat = $lxs->get;

raw()

Get raw values.
