  == Install the X-Ray daemon
  
  AWS X-Ray is a service that collects and analyzes data from your applications. A daemon is a process that runs in the background to do a job whenever it is needed. The X-Ray daemon uploads application metrics to X-Ray in batches to be processed. X-Ray then forwards this data to CloudWatch for display.
  
  To setup the daemon, log in to your EC2 instance and run the following commands:
  
  ```
  curl https://s3.dualstack.us-east-1.amazonaws.com/aws-xray-assets.us-east-1/xray-daemon/aws-xray-daemon-3.x.deb -o /home/ubuntu/xray.deb
