Dashing widget for puppetdb

README.md

##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.

Hi, Thanks for this widget.
I managed to get it working with SSL in the following manner - no need for the puppetdb-ruby gem

modify the code around the http=Net::HTTP.new section as follows :-

host = '<your puppetdb host/ip>'
port = '8081'
host_cert = '/var/lib/puppet/ssl/certs/<this servers hostname>.pem'
host_key = '/var/lib/puppet/ssl/private_keys/<this servers hostname>.pem'
http = Net::HTTP.new(host, port)
http.use_ssl = true
http.cert = OpenSSL::X509::Certificate.new(File.read(host_cert))
http.key = OpenSSL::PKey::RSA.new(File.read(host_key))
http.verify_mode = OpenSSL::SSL::VERIFY_NONE

Note - whichever user this runs under will need read access the the puppet ssl directory.

Hope this helps someone

I had to make some tweaks to get this working under PuppetDB 3.2; I created a "real" git repo here.

Hi, Thanks for this widget.
I'm a newbie and I'll have the following at startup:

Also I do not see the status of stations on widget. Say, what I miss?
