X-Ray Concepts
What can you find in a Segment?
The compute resources running your application logic send data about their work as segments.
There are 5 elements in the answer
The host – hostname, alias or IP address
The request – method, client address, path, user agent
The response – status, content
The work done – start and end times, subsegments
Issues that occur – errors, faults and exceptions, including automatic capture of exception stacks.
In X-Ray these key-value pairs are indexed for use in filter expressions and allow grouping traces in the console
