X ray

Basics

• X-Ray provides distributed tracing across multiple products
• When a user first connects to an application configured to use X-Ray, Trace Id is generated and inserted in a Tracing Header.
• The Trace Id is used to track a request throughout the lifecycle
• Supported services send data into X-Ray as segments.
• Segment consists of host/ip, request, response, timestamps, issues
• Segment can contain subsegments which have further granular information about requests within a segment
• X-Ray uses this data to create a Service Graph
• Service Map is a visual representation of Service Graph
• Some of the services that can use X-Ray are EC2, ECS, Lambda, BeanStalk, API Gateway, SNS, SQS
