A Ruby interface for getting system uptime information.

ffi 0.1.0 or later on Unixy platforms.

gem install sys-uptime

gem cert --add <(curl -Ls https://raw.githubusercontent.com/djberg96/sys-uptime/main/certs/djberg96_pub.pem)

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

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.

None that I am aware of. Please log any bugs you find on the project website at https://github.com/djberg96/sys-uptime.

"Doesn't Struct::Tms do this?" - No.
