NAME
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.METHODS
new()
Call new() to create a new object.
my $lxs = Sys::Statistics::Linux::DiskStats->new;Maybe you want to store/load the initial statistics to/from a file:
my $lxs = Sys::Statistics::Linux::DiskStats->new(initfile => '/tmp/diskstats.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::DiskStats->new(
files => {
# This is the default
path => '/proc',
diskstats => 'diskstats',
partitions => 'partitions',
}
);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.
