You have deployed an application on an EC2 Instance. This application makes calls to a DynamoDB service. There are numerous performance issues present in the application. You decide to use the XRay service to debug the performance issues. You are not able to see the trails in the XRay service. Which of the following could be the underlying issue? Choose 2 answers from the options given below.

Answer options:

A.The X-Ray daemon is not installed on the EC2 Instance.
B.The right AMI is not chosen for the EC2 Instance.
C.Ensure that the IAM Role attached to the Instance has permission to upload data onto X-Ray.
D.Ensure that the IAM Role attached to the Instance has permission to upload data onto Cloudwatch.

Answer – A and C
You need to have the daemon service running on the EC2 Instance. And a role needs to be attached to the EC2 Instance.
Running the X-Ray Daemon on Amazon EC2
You can run the X-Ray daemon on the following operating systems on Amazon EC2.
Amazon Linux
Ubuntu
Windows Server (2012 R2 and newer)
Use an instance profile to grant the daemon permission to upload trace data to X-Ray. For more information, see Giving the Daemon Permission to Send Data to X-Ray.
Option B is incorrect since the agent can be installed on different types of instances.
Option D is incorrect since the traces need to be sent to the X-Ray service.
