Description

Simple Dashing widget (and associated job) to display Pingdom checks.

##Dependencies

rest-client

Add it to dashing's gemfile:

gem 'rest-client'

and run bundle install. Everything should work now :)

##Usage

To use this widget, copy pingdom.html, pingdom.coffee, and pingdom.scss into the /widgets/pingdom directory. Put the pingdom.rb file in your /jobs folder.

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="1" data-sizey="1">
  <div data-id="pingdom" data-view="Pingdom" data-title="Pingdom" data-cols="1"></div>
</li>

##Settings

You'll need to add your pingdom API key and login settings. You can either add it straight to the source code on lines 4-6 of pingdom.rb, or set the variables in the ENV. For heroku, you can do this with

heroku config:set PINGDOM_API_KEY=
heroku config:set PINGDOM_USER=
heroku config:set PINGDOM_PASSWORD=
heroku config:set PINGDOM_TAGS=

Pingdom is checked every minute, but you can change that by editing the job schedule.

Contributions

This has been extracted from a dashboard for the UK Ministry of Justice, with minimal generalising. Feel free to submit patches to @james.

Modified by @jwalton to use rest-client instead of pingdom-client.

@anderm3 Added support for limiting Pingdom API response by tags
