SYNOPSIS

9           use Sys::Statistics::Linux::DiskStats;
10
11           my $lxs = Sys::Statistics::Linux::DiskStats->new;
12           $lxs->init;
13           sleep 1;
14           my $stat = $lxs->get;
15
16       Or
17
18           my $lxs = Sys::Statistics::Linux::DiskStats->new(initfile => $file);

DESCRIPTION

23       Sys::Statistics::Linux::DiskStats gathers disk statistics from the
24       virtual /proc filesystem (procfs).

DISK STATISTICS

30       Generated by /proc/diskstats or /proc/partitions.
31
32           major   -  The mayor number of the disk
33           minor   -  The minor number of the disk
34           rdreq   -  Number of read requests that were made to physical disk per second.
35           rdbyt   -  Number of bytes that were read from physical disk per second.
36           wrtreq  -  Number of write requests that were made to physical disk per second.
37           wrtbyt  -  Number of bytes that were written to physical disk per second.
38           ttreq   -  Total number of requests were made from/to physical disk per second.
39           ttbyt   -  Total number of bytes transmitted from/to physical disk per second.

METHODS

42   new()
43       Call "new()" to create a new object.
44
45           my $lxs = Sys::Statistics::Linux::DiskStats->new;
46
47       Maybe you want to store/load the initial statistics to/from a file:
48
49           my $lxs = Sys::Statistics::Linux::DiskStats->new(initfile => '/tmp/diskstats.yml');
50
51       If you set "initfile" it's not necessary to call sleep before "get()".
52
53       It's also possible to set the path to the proc filesystem.
54
55            Sys::Statistics::Linux::DiskStats->new(
56               files => {
57                   # This is the default
58                   path       => '/proc',
59                   diskstats  => 'diskstats',
60                   partitions => 'partitions',
61               }
62           );
63
64   init()
65       Call "init()" to initialize the statistics.
66
67           $lxs->init;
68
69   get()
70       Call "get()" to get the statistics. "get()" returns the statistics as a
71       hash reference.
72
73           my $stat = $lxs->get;
74
75   raw()
76       Get raw values.
