Sys::Statistics::Linux::PgSwStats(3pm) User Contributed Perl Documentation Sys::Statistics::Linux::PgSwStats(3pm) 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 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. 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()". 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', } ); 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; raw() Get raw values. EXPORTS

Sys::Statistics::Linux::DiskStats - Collect linux disk statistics. SYNOPSIS
use Sys::Statistics::Linux::DiskStats; my $lxs = Sys::Statistics::Linux::DiskStats->new; $lxs->init; sleep 1; my $stat = $lxs->get; Or my $lxs = Sys::Statistics::Linux::DiskStats->new(initfile => $file); $lxs->init; my $stat = $lxs->get; DESCRIPTION
Sys::Statistics::Linux::DiskStats gathers disk statistics from the virtual /proc filesystem (procfs). For more information read the documentation of the front-end module Sys::Statistics::Linux. DISK STATISTICS
Generated by /proc/diskstats or /proc/partitions. major - The mayor number of the disk minor - The minor number of the disk rdreq - Number of read requests that were made to physical disk per second. rdbyt - Number of bytes that were read from physical disk per second. wrtreq - Number of write requests that were made to physical disk per second. wrtbyt - Number of bytes that were written to physical disk per second. ttreq - Total number of requests were made from/to physical disk per second. ttbyt - Total number of bytes transmitted from/to physical disk per second.
