anchor.diff:  When you login to Datadog you will be taken to the Welcome page. Note
   the series of menu options on the left hand side.
   
  -To set up Datadog to manage the metrics available from Kill Bill, there
  -are just two steps: (1) install the Datadog agent in Kill Bill, and (2)
  -authorize the transfer of the complete Kill Bill metrics.
  -
  -== Install the Agent
  -
  -The first step in integrating an analysis tool (like Datadog) and a
  -source of data to analyze (like Kill Bill) is to set up a means to get
  -the source to send its data to the analyzer. Datadog does this by
  -installing the *Datadog Agent* in the system producing the data.
  -
  -1. In the main Datadog menu, select *Integrations*. 
  -2. Scroll down in the submenu to select *Agent*. This shows you a page listing all of the
  -platforms on which the Datadog Agent can be installed. 
  -3. Choose *Ubuntu*. The next page shows you the single step required for this platform
  -to install the agent:

  -
  -
  -To install the agent: 
  -
  -1. Login to your EC2 instance. 
  -2. Copy the line shown by Datadog to the Ubuntu command line. 
  -3. Press Enter. The agent should be installed automatically.
  -
  -[NOTE]
  -This command already includes the API key assigned to you by
  -Datadog. This authorizes the agent to do its job.
  -
  -If you are using the Multitier installation, you will have multiple EC2
  -instances. The agent should be installed separately for each one.
  -
  -To test the installation, return to datadog and choose *Infrastructure*,
  -then *Infrastructure List* from the left menu. The table that appears
  -should list all of your hosts and indicate their status as *ACTIVE*. You
  -may need to wait a few minutes for the table to appear.
  -
  -Now select *Metrics*, then *Summary* from the menu. You should see a
  -long list of metrics! These are coming from your instances, but they
  -only describe the Ubuntu environment itself. You do not yet have the
  -Kill Bill metrics. To fix this, proceed to the next step.
   
   == Set Up the Authorization
   
  
positive.code: edit two lines in this file:
  
  ```
  /var/lib/tomcat/bin/setenv2.sh`
  ```
  
  This file contains configuration information for `tomcat`, which manages the
  
negative.code: With the latest Amazon Machine Image (AMI)
  for Kill Bill, the application is preconfigured to collect these metrics and to direct them to Datadog once authorization is provided.
  
  To set up Datadog to manage the metrics available from Kill Bill, there
  are just two steps: (1) setup a Datadog account, and (2)
  edit a configuration file to enable the transfer of the complete Kill Bill metrics.
