NAME

Sys::Statistics::Linux::ProcStats - Collect linux load average 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 informations read the documentation of the front-end module Sys::Statistics::Linux.

LOAD AVERAGE STATISTICS

Generated by /proc/stat and /proc/loadavg.

    new           -  Number of new processes that were produced per second.
    runqueue      -  The number of processes waiting for runtime.
    count         -  The total amount of processes on the system.
    procs_blocked -  Number of processes blocked waiting for I/O to complete (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;

EXPORTS

No exports.
