Manual Reference Pages - UNIX::UPTIME (3)
Unix::Uptime - Determine the current uptime, in seconds, and load
averages, across different *NIX architectures
# Standard Usage
my $uptime = Unix::Uptime->uptime(); # 2345
# "HiRes" mode
use Unix::Uptime qw(:hires);
my $uptime = Unix::Uptime->uptime_hires(); # 2345.123593
# Load Average
my ($load1, $load5, $load15) = Unix::Uptime->load(); # (1.0, 2.0, 0.0)
This is a rather simple module that abstracts the task of figuring out
the current system uptime, in seconds. It was born out of a desire to do
this on non-Linux systems, without SNMP. If you want to use SNMP, there
are pleanty of modules on CPAN already.
Additionally, since version 0.33_02, it supports retrieving the load
Currently, this module just supports Linux, FreeBSD, Darwin (Mac OS X),
OpenBSD, and NetBSD. It should be easy enough to add support for other
operating systems, though.
While this module doesnt provide any functions for exporting, if the
tag :hires is given, then uptime_hires static method will be
available. It returns decimal numbers when possible, but on some systems
it is simply an alias for uptime(). This will likely
require the Time::HiRes module to be available. Otherwise, they will
simply be whole seconds.
The following static (class) methods are available:
This takes no arguments, and simply returns the number of seconds this
system has been running. This will always be an integer.
This is only available if the :hires import tag is used. It returns
the system uptime with a greater resolution than one second on supported
platforms. On some platforms, its results may not be any more precise
than uptime(), though. On different platforms, this requires
different additional modules:
No additional requirements.
Darwin, OpenBSD, NetBSD
No more precise than uptime()
This returns an array of the load averages for the last 1, 5, and 15
minutes. The degree of precision varies from system to system.
Sys::Load(3) and Sys::Uptime(3) for Linux-specific implementations.
Win32::Uptime for Win32.
This currently doesnt support more than Linux, FreeBSD, Darwin (Mac OS
X), OpenBSD, and NetBSD. Contributions for other operating systems would
<B>NOTE:B> This module is still a work in progress, under fairly heavy
development. While I think the final API should be mostly finalized at
this point, I wont commit to an API freeze until version 1.0.
