Sys::Statistics::Linux::PgSwStats (3pm)

    use Sys::Statistics::Linux::PgSwStats;

    my $lxs = Sys::Statistics::Linux::PgSwStats->new;
    $lxs->init;
    sleep 1;
    my $stat = $lxs->get;

Or

my $lxs = Sys::Statistics::Linux::PgSwStats->new(initfile => $file); $lxs->init; my $stat = $lxs->get;

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

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

Generated by /proc/stat or /proc/vmstat.

pgpgin - Number of pages the system has paged in from disk per second. pgpgout - Number of pages the system has paged out to disk per second. pswpin - Number of pages the system has swapped in from disk per second. pswpout - Number of pages the system has swapped out to disk per second.

The following statistics are only available by kernels from 2.6.

pgfault - Number of page faults the system has made per second (minor + major). pgmajfault - Number of major faults per second the system required loading a memory page from disk.

\fInew()\fP

Call \*(C`new()\*(C' to create a new object.

my $lxs = Sys::Statistics::Linux::PgSwStats->new;

Maybe you want to store/load the initial statistics to/from a file:

my $lxs = Sys::Statistics::Linux::PgSwStats->new(initfile => '/tmp/pgswstats.yml');

If you set \*(C`initfile\*(C' it's not necessary to call sleep before \*(C`get()\*(C'.

It's also possible to set the path to the proc filesystem.

Sys::Statistics::Linux::PgSwStats->new( files => { # This is the default path => '/proc', stat => 'stat', vmstat => 'vmstat', } );

\fIinit()\fP

Call \*(C`init()\*(C' to initialize the statistics.

$lxs->init;

\fIget()\fP

Call \*(C`get()\*(C' to get the statistics. \*(C`get()\*(C' returns the statistics as a hash reference.

my $stat = $lxs->get;

\fIraw()\fP

Get raw values.

No exports.
