anchor.diff:  These should be changed to:
   
   ```
  --Dcom.killbill.datadog.enable=true
  --Dcom.killbill.datadog.apiKey=`Your-API-Key`
  +-Dcom.killbill.newrelic.enable=true
  +-Dcom.killbill.newrelic.apiKey=Your-API-Key
   ```
   
   The API key to be added is called the *Insights Insert Key.* This is *not* the same as the user API Key contained in the command you
  
positive.code: than one instance, follow the same procedure for each one.
  
  Now return to the *Metrics/Summary* page. After a short delay, you
  should see a lot more metrics—well over 1,000 in your list.
  
  Congratulations. Your datadog integration is complete!
  
  == Using Datadog
  
  The Datadog site has lots of https://docs.datadoghq.com/[documentation], so we won't
  repeat any of that here. We will just suggest a few quick steps to get
  started:
  
  . Go to *Metrics* in the menu and *Explorer* in the submenu. Click on
  the field labeled *Graph:* to get a dropdown list of all available
  metrics.
  . Select some metrics to see the graph they produce. Identify the ones
  you would like to see together in a dashboard.
  . Gather the names of the metrics you want in the *Graph:* field
  together.
  . Under *Export these graphs to:* select *New Dashboard*. Give your
  dashboard a name.
  
  Your dashboard will appear in the *Dashboard List* under the
  *Dashboards* menu item. You can create and modify multiple dashboards.
  You can also adjust the graphs in many ways, and do lots of other things
  like setting alarms. Have fun and good luck!
