[AWS] X-Ray

X-Ray traces applications and helps to identify potential problems or optimizations in the applications. It provides a visualization of your application’s underlying components.


Features

The X-Ray Service Map provides an end-to-end view of requests as they travel through your application. It allows you to troubleshoot the root cause of connection/performance issues and errors.

  • Segments
    • data about the work done by application (request, response, issues …)
  • Subsegments
    • a more granular view of data inside of segments
  • Service Graph
    • a JSON document of how the application’s services and resources interact (visualized)
  • Traces
    • At first, HTTP trace ID header -> and propagates downstream to track through the system

X-Ray can track application errors

  • Errors (Client error – 400)
  • Fault (Server error – 500)
  • Throttle (429 Too many requests)

X-Ray Architecture

  • The X-Ray agent must be installed on your EC2 instance.
  • Configure your applications using the X-Ray SDK
    • The X-Ray SDK gathers information from request and response headers, the code in your application, and metadata about the AWS resources on which it runs, and sends this trace data to X-Ray. e.g. incoming HTTP requests, error codes, latency data.

X-Ray Daemon

X-Ray Daemon is an AWS application that

  • listens on UDO port 2000
  • collects raw segment data
  • sends it to the AWS X-Ray API

Integration

X-Ray integrates with AWS Services or custom applications.

  • AWS Services
    • EC2, Lambda, Elastic Beanstalk, SNS, SQS, DynamoDB, Elastic Load Balancer, Elastic Container Service, and API Gateway.
  • Custom Application
    • applications written in .NET, Java, Node.js, Go, Ruby, or Python.
  • The X-Ray SDK automatically captures metadata for API calls made to AWS services using the AWS SDK.
