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

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 }
