NAME

Linux::Info::DiskStats - Collect linux disk statistics.

SYNOPSIS

    use Linux::Info::DiskStats;

    my $lxs = Linux::Info::DiskStats->new;
    $lxs->init;
    sleep 1;
    my $stat = $lxs->get;

Or

    my $lxs = Linux::Info::DiskStats->new(initfile => $file);
    $lxs->init;
    my $stat = $lxs->get;

DESCRIPTION

Linux::Info::DiskStats gathers disk statistics from the virtual /proc filesystem (procfs).

For more information read the documentation of the front-end module Linux::Info.

DISK STATISTICS

Generated by /proc/diskstats or /proc/partitions.

    major   -  The mayor number of the disk
    minor   -  The minor number of the disk
    rdreq   -  Number of read requests that were made to physical disk per second.
    rdbyt   -  Number of bytes that were read from physical disk per second.
    wrtreq  -  Number of write requests that were made to physical disk per second.
    wrtbyt  -  Number of bytes that were written to physical disk per second.
    ttreq   -  Total number of requests were made from/to physical disk per second.
    ttbyt   -  Total number of bytes transmitted from/to physical disk per second.

METHODS

new()

Call new() to create a new object.

    my $lxs = Linux::Info::DiskStats->new;

Maybe you want to store/load the initial statistics to/from a file:

    my $lxs = Linux::Info::DiskStats->new(initfile => '/tmp/diskstats.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.

     Linux::Info::DiskStats->new(
        files => {
            # This is the default
            path       => '/proc',
            diskstats  => 'diskstats',
            partitions => 'partitions',
        }
    );

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.

EXPORTS

Nothing.
