NAME

6       Rex::Commands::Gather - Hardware and Information gathering
7

DESCRIPTION

9       With this module you can gather hardware and software information.
10
11       All these functions will not be reported. These functions don't modify
12       anything.
13

SYNOPSIS

15        operating_system_is("SuSE");
16

EXPORTED FUNCTIONS

18   get_operating_system
19       Will return the current operating system name.
20
21        task "get-os", "server01", sub {
22          say get_operating_system();
23        };
24
25       Aliased by operating_system().
26
27   operating_system
28       Alias for get_operating_system()
29
30   get_system_information
31       Will return a hash of all system information. These Information will be
32       also used by the template function.
33
34   kernelname
35       Will return the kernel name of the operating system. For example on a
36       linux system it will return Linux.
37
38   dump_system_information
39       This function dumps all known system information on stdout.
40
41   operating_system_is($string)
42       Will return 1 if the operating system is $string.
43
44        task "is_it_suse", "server01", sub {
45          if( operating_system_is("SuSE") ) {
46            say "This is a SuSE system.";
47          }
48        };
49
50   operating_system_version()
51       Will return the os release number as an integer. For example, it will
52       convert 5.10 to 510, 10.04 to 1004 or 6.0.3 to 603.
53
54        task "prepare", "server01", sub {
55          if( operating_system_version() >= 510 ) {
56            say "OS Release is higher or equal to 510";
57          }
58        };
59
60   operating_system_release()
61       Will return the os release number as is.
62
63   network_interfaces

69
70       You can iterate over the devices as follow
71
72        my $net_info = network_interfaces();
73        for my $dev ( keys %{ $net_info } ) {
74          say "$dev has the ip: " . $net_info->{$dev}->{"ip"} . " and the netmask: " . $net_info->{$dev}->{"netmask"};
75        }
76
77   memory
78       Return an HashRef of all memory information.
79

84          say "Free:   " . $memory->{"free"};
85          say "Used:   " . $memory->{"used"};
86          say "Cached:  " . $memory->{"cached"};
