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

DESCRIPTION

With this module you can gather hardware and software information.

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();
 };

get_system_information

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

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";
    }
 };

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 interate 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"};
 };

is_freebsd

Returns true if the target system is a FreeBSD.

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

is_redhat

 task "foo", "server1", sub {
    if(is_redhat) {
       # do something on a redhat system (like RHEL, Fedora, CentOS, Scientific Linux
    }
 };

is_suse

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

is_debian

 task "foo", "server1", sub {
    if(is_debian) {
       # do something on a debian 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...";
    }
    else {
       say "This is not an openbsd system...";
    }
 };

is_linux

Returns true if the target system is a Linux System.

 task "prepare", "server1", "server2", sub {
    if(is_linux) {
      say "This is a linux system...";
    }
    else {
      say "This is not a linux system...";
    }
 };

is_bsd

Returns true if the target system is a BSD System.

 task "prepare", "server1", "server2", sub {
    if(is_bsd) {
      say "This is a BSD system...";
    }
    else {
      say "This is not a BSD system...";
    }
 };

is_solaris

Returns true if the target system is a Solaris System.

 task "prepare", "server1", "server2", sub {
    if(is_solaris) {
      say "This is a Solaris system...";
    }
    else {
      say "This is not a Solaris system...";
    }
 };
