AWS-X-Ray

• X-Ray helps developers analyze & debug production distributed applications.

• It provides an end-to-end view of requests as they travel through application & shows a map of application’s underlying components.

• It can automatically highlight bugs or errors in application code by analyzing the response code for each request made to application.

• It provides a set of APIs for ingesting request data, querying traces and configuring the service.

• An X-Ray segment encapsulates all the data points for a single component of the distributed application.

• It errors are system annotations associated with a segment for a call that results in an error response.

• It agent collects data from log files and sends them to the X-Ray service for aggregation, analysis & storage.

• It can be used with distributed applications of any size to trace and debug both synchronous requests and asynchronous events.

• Trace data sent to X-Ray is generally available for retrieval and filtering within 30 seconds of it being received by the service.

• It agent can assume a role to publish data into an account different from the one in which it is running.
