XRay
A service that can be used to collect cross-workload traffic metrics and information. - allows users to understand how requests travel through their applications - integrates with CloudWatch where X-Ray data can be analyzed in greater detail
- You have to prepare your apps for tracing with XRay
- add extra code
- install a daemon service in the app environment
- save tracing events with certain code snippets → the daemon sends that data back to AWS & you can analyze these traces
- analyze traces
- view traffic flow across applications/services
- can be combined with other monitoring tools like CloudWatch for more detailed insight
