AWS X-Ray | Data Handling

Question 1

Can I use X-Ray to track requests from applications or services spread across multiple regions?

Answer 1

Yes, you can use X-Ray to track requests flowing through applications or services across multiple regions. X-Ray data is stored locally to the processed region but with enough information to enable client applications to combine the data and provide a global view of traces. Region annotation for AWS services will be added automatically, however, customers will need to instrument custom services to add the regional annotation to make use of the cross-region support.

Question 2

How long does it take for trace data to be available in X-Ray?

Answer 3

X-Ray stores trace data for the last 30 days. This enables you to query trace data going back 30 days.

Question 4

Why do I sometimes see partial traces?

Answer 4

X-Ray makes the best effort to present complete trace information. However, in some situations (connectivity issues, delay in receiving segments, and so on) it is possible that trace information provided by the X-Ray APIs will be partial. In those situations, X-Ray tags traces as incomplete or partial.
