Description

A Ruby interface for getting system uptime information.

Prerequisites

ffi 0.1.0 or later on Unixy platforms.

Installation

gem install sys-uptime

Synopsis

require 'sys-uptime'
include Sys

# Get everything
p Uptime.uptime
p Uptime.dhms.join(', ')

# Get individual units
p Uptime.days
p Uptime.hours
p Uptime.minutes
p Uptime.seconds

# Get the boot time
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 https://github.com/djberg96/sys-uptime.
