aws x-ray analysis and debugging

X-Ray is a tool which helps developers analyze and debug distributed applications.

This allows developers to troubleshoot the root cause of performance issues and errors by providing a visualization of the application's underlying components.

Example X-Ray service map visualizing requests:

X-Ray integrations

• AWS services:
  • EC2
  • ECS
  • Lambda
  • Elastic Beanstalk
  • SNS
  • SQS
  • DynamoDB
  • ELB
  • API Gateway
• Integrate with apps:
  • Java
  • Node.js
  • .NET
  • Go
  • Ruby
  • Python
• API Calls
  • X-Ray SDK captures metadata for API calls made to AWS services using
  the AWS SDK

X-Ray architecture

1. Install the X-Ray Agent on the EC2 instance
2. Instrument the application using X-Ray SDK (configure)
3. X-Ray SDK gathers information from:
   1. Request and response headers
   2. Code in your application
   3. Metadata about AWS resources on which it runs

Exam tips

• X-Ray helps developers analyze and debug distributed applications
• Provides a visual service map of your application
• X-Ray Agent and the SDK need to be installed and configured on your EC2 instance
  • The SDK instruments the application to send traces to X-Ray
