Description

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

##Dependencies

pingdom-client

Add it to dashing's gemfile:

gem 'pingdom-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=

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

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

Hmm I get errors using the gem specified, because of a Faraday dependency conflict. When using another Github fork of the library, I get

scheduler caught exception:
:logger is not registered on Faraday::Adapter
/Users/matthijsgroen/dashing/vendor/bundle/ruby/1.9.1/gems/faraday-0.8.7/lib/faraday.rb:64:in `lookup_middleware'
/

This is my version: https://gist.github.com/jwalton/6625777

It removes the dependency on pingdom-client, and thus the troublesome Faraday problems, and adds showing the most recent ping for each server.

@james feel free to pull from mine. :)

@jwalton @james https://gist.github.com/james/5670035#file-pingdom-rb-L21 should be:

checks.sort_by! { |check| check[:name] }

Hello,

I have a question, how can i change did so it just shows the down checks, because we have something like more than 40 checks in pingdom so it doesn't fit on the screen.
