AWS X-Ray

What is AWS X-Ray?

AWS X-Ray helps to analyze and debug production systems in distributed environments. AWS X-Ray is a method used to profile and monitor applications, mostly built using microservice architecture.

Using X-Ray service features, it’s very easy for a user to troubleshoot and find the root cause of slowness of the system, including other performance-related errors.

● Daemon: a unique application that collects related segment data.

● Segments: provides resource names, requests information.

● Subsegments: This provides granular details about downstream calls.

● Service Graph: Visual representation of micro-service response or failure.

● Traces: Collects all segments created from a single request.

● Sampling: Algorithm which decides which request needs to be traced.

● Filter Expressions: easier to deep dive to understand the particular path.
