##Description Simple Dashing widget (and associated job) to display general puppetdb status. Pulled the api calls from Nedap's Puppetboard. Excellent tool BTW.

WARNING: This only works if puppetdb is listening on HTTP. I have not gotten around to getting this to work with SSL client certificates yet. If you know how, please leave them at the comments below.

##Dependencies None

##Usage To use this widget, copy puppetdb_stats.html, puppetdb_stats.coffee, and puppetdb_stats.scss into the /widgets/puppetdb_stats directory. Put the puppetdb_stats.rb file in your /jobs folder. Or you can do this the easy way and run the following in your dashing directory

$> dashing install a49981b299dff184c04a
  create  widgets/puppetdb_stats/puppetdb_stats.coffee
  create  widgets/puppetdb_stats/puppetdb_stats.html
  create  jobs/puppetdb_stats.rb
  create  widgets/puppetdb_stats/puppetdb_stats.scss
Don't forget to edit the Gemfile and run bundle install if needed. More information for this widget can be found at https://gist.github.com/a49981b299dff184c04a

To include the widget in a dashboard, add the following snippet to the dashboard layout file:

<li data-row="1" data-col="1" data-sizex="2" data-sizey="1">
  <div data-id="puppetdb_stats" data-view="PuppetdbStats"></div>
</li>

puppetdb_stats.coffee

class Dashing.PuppetdbStats extends Dashing.Widget

  ready: ->
    # This is fired when the widget is done being rendered

  onData: (data) ->
    # Handle incoming data
    # You can access the html node of this widget with `@node`
    # Example: $(@node).fadeOut().fadeIn() will make the node flash each time data comes in.
