  +edit two lines in the file `/var/lib/tomcat/bin/setenv2.sh`. This file
  +contains configuration information for `tomcat`, which manages the
   KillBill web applications.
   
   This is a small file. The two lines to be edited are:
   
  +```
   -Dcom.killbill.datadog.enable=false
  -
   -Dcom.killbill.datadog.apiKey=
  +```
   
   These should be changed to
   
  +```
   -Dcom.killbill.datadog.enable=true
  -
   -Dcom.killbill.datadog.apiKey=__Your-API-Key__
  +```
   
   The API Key to be added is the same one contained in the command you
   used to install the agent.

  Measurements and metrics are an important part of managing your Kill
  Bill system to be sure that performance is optimized and any problems
  
negative.code: You should be running Kill Bill version 2021.9 or later. This version
  can be configured to provide its full collection of Kill Bill metrics to
  datadog (and several other analysis tools). If you open the Kill Bill
  admin page in your browser, it should show that you are
  running the "Kill Bill Premium edition":

  If you see this page you are ready to go. If not, you should upgrade
  your installation.
  
  While you are on this page, if you want to see all the metrics that Kill
  Bill has to offer, just add the path `/1.0/metrics` to the URL. Have fun!
  If you find these hard to understand, though, maybe datadog can help.
