6 Rex::Commands::Gather - Hardware and Information gathering
7
9 With this module you can gather hardware and software information.
10 All these functions will not be reported. These functions don't modify
12 anything.
13
15 operating_system_is("SuSE");
16
18 get_operating_system
19 Will return the current operating system name.
20 task "get-os", "server01", sub {
22 say get_operating_system();
23 };
24 Aliased by operating_system().
26 operating_system
28 Alias for get_operating_system()
29 get_system_information
31 Will return a hash of all system information. These Information will be
32 also used by the template function.
33 kernelname
35 Will return the kernel name of the operating system. For example on a
36 linux system it will return Linux.
37 dump_system_information
39 This function dumps all known system information on stdout.
40 operating_system_is($string)
42 Will return 1 if the operating system is $string.
43 task "is_it_suse", "server01", sub {
45 if( operating_system_is("SuSE") ) {
46 say "This is a SuSE system.";
47 }
48 };
49 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 task "prepare", "server01", sub {
55 if( operating_system_version() >= 510 ) {
56 say "OS Release is higher or equal to 510";
57 }
58 };
59 operating_system_release()
61 Will return the os release number as is.
62 network_interfaces
64 Return an HashRef of all the networkinterfaces and their configuration.
65 task "get_network_information", "server01", sub {
67 my $net_info = network_interfaces();
68 };
69 You can iterate over the devices as follow
71 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 memory
78 Return an HashRef of all memory information.
79 task "get_memory_information", "server01", sub {
81 my $memory = memory();
82 say "Total: " . $memory->{"total"};
84 say "Free: " . $memory->{"free"};
85 say "Used: " . $memory->{"used"};
86 say "Cached: " . $memory->{"cached"};
87 say "Buffers: " . $memory->{"buffers"};
88 };
89 is_freebsd
91 Returns true if the target system is a FreeBSD.
92 task "foo", "server1", "server2", sub {
94 if(is_freebsd) {
