Load averages of *nix server running dashing.

README.md

Setup

Put the loadavg1min.rb to jobs/loadavg1min.rb.

Add the code from loadavg1min.erb to the desired dashboard.

Preview

loadavg1min.erb

    <li data-row="1" data-col="1" data-sizex="1" data-sizey="1">
      <div data-id="loadavg1min" data-view="Graph" data-title="Server load" style="background-color:#47bbb3;" data-moreinfo="1 min intervals" ></div>
    </li>

loadavg1min.rb

# Populate the graph with 0.00 results
points = []
(1..10).each do |i|
  points << { x: i, y: 0 }
end
last_x = points.last[:x]

SCHEDULER.every '1m' do
  points.shift
  last_x += 1
  uptime = %x('uptime')
  points << { x: last_x, y: uptime[-17..-14].to_f }

  send_event('loadavg1min', points: points)
end

Ok, I'm no longer using IO.popen to prevent the zombies

Someone knows how to get info of another machines?

Maybe try to get load info by running script like this (on remote machine, using cron):

X=$(uptime | cut -c46-49)
LOAD='{ "auth_token": "YOUR_AUTH_TOKEN", "value" : '$X' }'
curl -d "${LOAD}" \http://dashing_url:3030/widgets/widget_name

I used the following to get this to work on both OS X and Linux:

  uptime = %x('uptime').gsub(/.*: /, '\1').gsub(/,/, '\1')
  points << { x: last_x, y: uptime[0..3].to_f }
