AWS X-Ray Adds the Ability to Group Traces by Root Cause

X-Ray now automatically analyzes your traces and assigns to one or more root causes. This enables you to filter traces by a particular root cause and quickly determine whether same error or faults are behind performance issues. 

You don’t need to make any changes to use this feature. You can simply navigate to the trace list and click the ‘group by’ drop down to filter by root causes. You can learn more about AWS X-Ray here or visit our developer Getting Started guide.
