NAME
       Sys::Statistics::Linux::DiskStats - Collect linux disk statistics.

SYNOPSIS
	   use Sys::Statistics::Linux::DiskStats;

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

       Or

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

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

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

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 = Sys::Statistics::Linux::DiskStats->new;

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

	   my $lxs = Sys::Statistics::Linux::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.

	    Sys::Statistics::Linux::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
