KaufKauf Slim Linux is a fully configured Linux-based operating system that is able to run from flash memory. It doesn't require more than 500 MBytes of disk-space. It comes with full support for TouchKit touch controllers and is made to run on weak systems (200 MHz CPU and 128 MBytes RAM are enough).

Sys::Statistics::Linux::PgSwStats(3pm)			User Contributed Perl Documentation		    Sys::Statistics::Linux::PgSwStats(3pm)

NAME

       Sys::Statistics::Linux::PgSwStats - Collect linux paging and swapping statistics.

SYNOPSIS

	   use Sys::Statistics::Linux::PgSwStats;

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

       Or

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

DESCRIPTION

       Sys::Statistics::Linux::PgSwStats gathers paging and swapping statistics from the virtual /proc filesystem (procfs).

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

PAGING AND SWAPPING STATISTICS

       Generated by /proc/stat or /proc/vmstat.

	   pgpgin      -  Number of pages the system has paged in from disk per second.
	   pgpgout     -  Number of pages the system has paged out to disk per second.
	   pswpin      -  Number of pages the system has swapped in from disk per second.
	   pswpout     -  Number of pages the system has swapped out to disk per second.

	   The following statistics are only available by kernels from 2.6.

	   pgfault     -  Number of page faults the system has made per second (minor + major).
	   pgmajfault  -  Number of major faults per second the system required loading a memory page from disk.

METHODS

   new()
       Call "new()" to create a new object.

	   my $lxs = Sys::Statistics::Linux::PgSwStats->new;

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

	   my $lxs = Sys::Statistics::Linux::PgSwStats->new(initfile => '/tmp/pgswstats.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::PgSwStats->new(
	       files => {
		   # This is the default
		   path   => '/proc',
		   stat   => 'stat',
		   vmstat => 'vmstat',
	       }
	   );

   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.
