NAME

       Sys::Statistics::Linux::FileStats - Collect linux file statistics.

SYNOPSIS

	   use Sys::Statistics::Linux::FileStats;

	   my $lxs  = Sys::Statistics::Linux::FileStats->new;
	   my $stat = $lxs->get;

DESCRIPTION

       Sys::Statistics::Linux::FileStats gathers file statistics from the virtual /proc filesystem (procfs).

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

FILE STATISTICS

       Generated by /proc/sys/fs/file-nr, /proc/sys/fs/inode-nr and /proc/sys/fs/dentry-state.

	   fhalloc    -  Number of allocated file handles.
	   fhfree     -  Number of free file handles.
	   fhmax      -  Number of maximum file handles.
	   inalloc    -  Number of allocated inodes.
	   infree     -  Number of free inodes.
	   inmax      -  Number of maximum inodes.
	   dentries   -  Dirty directory cache entries.
	   unused     -  Free diretory cache size.
	   agelimit   -  Time in seconds the dirty cache entries can be reclaimed.
	   wantpages  -  Pages that are requested by the system when memory is short.

METHODS

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

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

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

	    Sys::Statistics::Linux::FileStats->new(
	       files => {
		   # This is the default
		   path     => '/proc',
		   file_nr  => 'sys/fs/file-nr',
		   inode_nr => 'sys/fs/inode-nr',
		   dentries => 'sys/fs/dentry-state',
	       }
	   );

   get()
       Call "get()" to get the statistics. "get()" returns the statistics as a hash reference.

	   my $stat = $lxs->get;
