DESCRIPTION

24       Sys::Statistics::Linux::PgSwStats gathers paging and swapping
25       statistics from the virtual /proc filesystem (procfs).

27       For more information read the documentation of the front-end module
28       Sys::Statistics::Linux.

PAGING AND SWAPPING STATISTICS

31       Generated by /proc/stat or /proc/vmstat.
32
33           pgpgin      -  Number of pages the system has paged in from disk per second.
34           pgpgout     -  Number of pages the system has paged out to disk per second.
35           pswpin      -  Number of pages the system has swapped in from disk per second.
36           pswpout     -  Number of pages the system has swapped out to disk per second.
37
38           The following statistics are only available by kernels from 2.6.
39
40           pgfault     -  Number of page faults the system has made per second (minor + major).
41           pgmajfault  -  Number of major faults per second the system required loading a memory page from disk.

METHODS

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