    Description
A Dashing widget that checks whether a server is responding to either an http or ping request. It displays either a check or alert depending on the response.

Usage

Add the widget HTML to your dashboard

    <li data-row="1" data-col="1" data-sizex="1" data-sizey="1">
      <div data-id="server_status" data-view="ServerStatus" data-title="Server Status"></div>
    </li>


Create a directory titled "server_status" under your widgets directory and move server_status.coffee, server_status.html, and server_status.scss into that directory.


Modify the servers array of the server_status.rb file.


Move server_status.rb into your jobs folder.


## server_status.coffee
class Dashing.ServerStatus extends Dashing.Widget

## server_status.erb
<li data-row="1" data-col="1" data-sizex="1" data-sizey="1">
  <div data-id="server_status" data-view="ServerStatus" data-title="Server Status"></div>
</li>
