Changes GetTraceSummaries - Now provides additional root cause attribute ClientImpacting which indicates whether root cause impacted trace client.
Changes AWS X-Ray now includes Analytics, an interactive approach to analyzing user request paths (i.e., traces). Analytics will allow you to easily understand how your application and its underlying services are performing. With X-Ray Analytics, you can quickly detect application issues, pinpoint the root cause of the issue, determine the severity of the issues, and identify which end users were impacted. With AWS X-Ray Analytics you can explore, analyze, and visualize traces, allowing you to find increases in response time to user requests or increases in error rates. Metadata around peak periods, including frequency and actual times of occurrence, can be investigated by applying filters with a few clicks. You can then drill down on specific errors, faults, and response time root causes and view the associated traces.
Changes GetTraceSummaries - Now provides additional information regarding your application traces such as Availability Zone, Instance ID, Resource ARN details, Revision, Entry Point, Root Cause Exceptions and Root Causes for Fault, Error and Response Time.
Changes Groups build upon X-Ray filter expressions to allow for fine tuning trace summaries and service graph results. You can configure groups by using the AWS X-Ray console or by using the CreateGroup API. The addition of groups has extended the available request fields to the GetServiceGraph API. You can now specify a group name or group ARN to retrieve its service graph.
Changes Support for new APIs that enable management of sampling rules.
Changes Added PutEncryptionConfig and GetEncryptionConfig APIs for managing data encryption settings. Use PutEncryptionConfig to configure X-Ray to use an AWS Key Management Service customer master key to encrypt trace data at rest.
Changes Add a response time histogram to the services in response of GetServiceGraph API.
Changes AWS X-Ray helps developers analyze and debug distributed applications. With X-Ray, you can understand how your application and its underlying services are performing to identify and troubleshoot the root cause of performance issues and errors.
