Description
A Ruby interface for getting system uptime information.
Prerequisites
ffi 0.5.0 or later.
Installation
gem install sys-uptime # Unix platforms
gem install sys-uptime --platform mswin32 # MS Windows
Synopsis
require 'sys/uptime'
include Sys
p Uptime.uptime
p Uptime.dhms.join(', ')
p Uptime.days
p Uptime.hours
p Uptime.minutes
p Uptime.seconds
p Uptime.boot_time
Notes
On MS Windows the Uptime.uptime and Uptime_boot_time methods optionally
takes a host name as a single argument. The default is localhost.
The current time, users and load average are not included in this library
module, even though you may be used to seeing them with the command
line version of 'uptime'.
Known Bugs
None that I am aware of. Please log any bugs you find on the project
website at http://www.rubyforge.org/projects/sysutils.
