SYNOPSIS

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

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

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.

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.
