Rex::Commands::Gather(3)

NAME
Rex::Commands::Gather - Hardware and Information gathering

DESCRIPTION
With this module you can gather hardware and software information.

All these functions will not be reported. These functions don't modify anything.

SYNOPSIS
 operating_system_is("SuSE");

EXPORTED FUNCTIONS

  get_operating_system
Will return the current operating system name.

 task "get-os", "server01", sub {
   say get_operating_system();
 };

Aliased by operating_system().

  operating_system
Alias for get_operating_system()

  get_system_information
Will return a hash of all system information. These Information will be also used by the template function.

  kernelname
Will return the kernel name of the operating system. For example on a linux system it will return Linux.

  dump_system_information
This function dumps all known system information on stdout.

  operating_system_is($string)
Will return 1 if the operating system is $string.

 task "is_it_suse", "server01", sub {
   if( operating_system_is("SuSE") ) {
     say "This is a SuSE system.";
   }
 };

  operating_system_version()
Will return the os release number as an integer. For example, it will convert 5.10 to 510, 10.04 to 1004 or 6.0.3 to 603.

 task "prepare", "server01", sub {
   if( operating_system_version() >= 510 ) {
     say "OS Release is higher or equal to 510";
   }
 };

  operating_system_release()
Will return the os release number as is.

  network_interfaces
Return an HashRef of all the networkinterfaces and their configuration.

 task "get_network_information", "server01", sub {
   my $net_info = network_interfaces();
 };

You can iterate over the devices as follow

 my $net_info = network_interfaces();
 for my $dev ( keys %{ $net_info } ) {
   say "$dev has the ip: " . $net_info->{$dev}->{"ip"} . " and the netmask: " . $net_info->{$dev}->{"netmask"};
 }

  memory
Return an HashRef of all memory information.

 task "get_memory_information", "server01", sub {
   my $memory = memory();

   say "Total:  " . $memory->{"total"};
   say "Free:   " . $memory->{"free"};
   say "Used:   " . $memory->{"used"};
   say "Cached:  " . $memory->{"cached"};
   say "Buffers: " . $memory->{"buffers"};
 };

 task "foo", "server1", "server2", sub {
   if(is_freebsd) {
     say "This is a freebsd system...";

   if(is_mageia) {
     # do something on a mageia system (or other Mandriva followers)
   }
 };

  is_debian
 task "foo", "server1", sub {
   if(is_debian) {
     # do something on a debian system
   }
 };

  is_alt
 task "foo", "server1", sub {
   if(is_alt) {
     # do something on a ALT Linux system
   }
 };

  is_netbsd
Returns true if the target system is a NetBSD.

 task "foo", "server1", "server2", sub {
   if(is_netbsd) {
     say "This is a netbsd system...";
   }
   else {
     say "This is not a netbsd system...";
   }
 };

  is_openbsd
Returns true if the target system is an OpenBSD.

 task "foo", "server1", "server2", sub {
   if(is_openbsd) {
     say "This is an openbsd system...";
