API Reference (API Version 2016-04-12)

PutTraceSegments

Uploads segment documents to AWS X-Ray. The X-Ray SDK generates segment documents and sends them to the X-Ray daemon, which uploads them in batches. A segment document can be a completed segment, an in-progress segment, or an array of subsegments.

Segments must include the following fields. For the full segment document schema, see AWS X-Ray Segment Documents in the AWS X-Ray Developer Guide.

Required Segment Document Fields

  • name - The name of the service that handled the request.

  • id - A 64-bit identifier for the segment, unique among segments in the same trace, in 16 hexadecimal digits.

  • trace_id - A unique identifier that connects all segments and subsegments originating from a single client request.

  • start_time - Time the segment or subsegment was created, in floating point seconds in epoch time, accurate to milliseconds. For example, 1480615200.010 or 1.480615200010E9.

  • end_time - Time the segment or subsegment was closed. For example, 1480615200.090 or 1.480615200090E9. Specify either an end_time or in_progress.

  • in_progress - Set to true instead of specifying an end_time to record that a segment has been started, but is not complete. Send an in progress segment when your application receives a request that will take a long time to serve, to trace the fact that the request was received. When the response is sent, send the complete segment to overwrite the in-progress segment.

A trace_id consists of three numbers separated by hyphens. For example, 1-58406520-a006649127e371903a2de979. This includes:

Trace ID Format

  • The version number, i.e. 1.

  • The time of the original request, in Unix epoch time, in 8 hexadecimal digits. For example, 10:00AM December 2nd, 2016 PST in epoch time is 1480615200 seconds, or 58406520 in hexadecimal.

  • A 96-bit identifier for the trace, globally unique, in 24 hexadecimal digits.
