NAME
Sys::Statistics::Linux::PgSwStats - Collect linux paging and swapping statistics.SYNOPSIS
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;
DESCRIPTION
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.
PAGING AND SWAPPING STATISTICS
Generated by /proc/stat or /proc/vmstat.pgpgin - Number of kilobytes the system has paged in from disk per second. pgpgout - Number of kilobytes the system has paged out to disk per second. pswpin - Number of kilobytes the system has swapped in from disk per second. pswpout - Number of kilobytes 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.
METHODS
new()
Call "new()" 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 $lxs = Sys::Statistics::Linux::PgSwStats->new(initfile => '/tmp/pgswstats.yml');
If you set "initfile" it's not necessary to call sleep before "get()".
init()
Call "init()" to initialize the statistics.$lxs->init;
get()
Call "get()" to get the statistics. "get()" returns the statistics as a hash reference.my $stat = $lxs->get;
