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

NAME

       Sys::Statistics::Linux::SysInfo - Collect linux system information.

SYNOPSIS

	   use Sys::Statistics::Linux::SysInfo;

	   my $lxs  = Sys::Statistics::Linux::SysInfo->new;
	   my $info = $lxs->get;

DESCRIPTION

       Sys::Statistics::Linux::SysInfo gathers system information from the virtual /proc filesystem (procfs).

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

SYSTEM INFOMATIONS

       Generated by /proc/sys/kernel/{hostname,domainname,ostype,osrelease,version} and /proc/cpuinfo, /proc/meminfo, /proc/uptime, /proc/net/dev.

	   hostname   -  The host name.
	   domain     -  The host domain name.
	   kernel     -  The kernel name.
	   release    -  The kernel release.
	   version    -  The kernel version.
	   memtotal   -  The total size of memory.
	   swaptotal  -  The total size of swap space.
	   uptime     -  The uptime of the system.
	   idletime   -  The idle time of the system.
	   pcpucount  -  The total number of physical CPUs.
	   tcpucount  -  The total number of CPUs (cores, hyper threading).
	   interfaces -  The interfaces of the system.
	   arch       -  The machine hardware name (uname -m).

	   # countcpus is the same like tcpucount
	   countcpus  -  The total (maybe logical) number of CPUs.

       "pcpucount" and "tcpucount" are really easy to understand. Both values are collected from "/proc/cpuinfo". "pcpucount" is the number of
       physical CPUs, counted by "physical id". "tcpucount" is just the total number counted by "processor".

       If you want to get "uptime" and "idletime" as raw value you can set

	   $Sys::Statistics::Linux::SysInfo::RAWTIME = 1;
	   # or with
	   Sys::Statistics::Linux::SysInfo->new(rawtime => 1)

METHODS

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

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

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

	   my $info = $lxs->get;

EXPORTS

       No exports.
