Uploads segment documents to Amazon Web Services 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 Amazon Web Services X-Ray Segment Documents in the Amazon Web Services 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 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, for instance, 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.

put-trace-segments
--trace-segment-documents <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
--trace-segment-documents
(list)
A string containing a JSON document defining one or more segments or subsegments.
(string)
Syntax:
"string" "string" ...
--cli-input-json
| --cli-input-yaml
(string)
Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton
. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml
.
--generate-cli-skeleton
(string)
Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input
, prints a sample input JSON that can be used as an argument for --cli-input-json
. Similarly, if provided yaml-input
it will print a sample input YAML that can be used with --cli-input-yaml
. If provided with the value output
, it validates the command inputs and returns a sample output JSON for that command.
See ‘aws help’ for descriptions of global parameters.
To upload a segment
The following put-trace-segments
example uploads segment documents to AWS X-Ray. The segment document is consumed as a list of JSON segment documents.
aws xray put-trace-segments \
--trace-segment-documents "{\"id\":\"20312a0e2b8809f4\",\"name\":\"DynamoDB\",\"trace_id\":\"1-5832862d-a43aafded3334a971fe312db\",\"start_time\":1.479706157195E9,\"end_time\":1.479706157202E9,\"parent_id\":\"79736b962fe3239e\",\"http\":{\"response\":{\"content_length\":60,\"status\":200}},\"inferred\":true,\"aws\":{\"consistent_read\":false,\"table_name\":\"scorekeep-session-xray\",\"operation\":\"GetItem\",\"request_id\":\"SCAU23OM6M8FO38UASGC7785ARVV4KQNSO5AEMVJF66Q9ASUAAJG\",\"resource_names\":[\"scorekeep-session-xray\"]},\"origin\":\"AWS::DynamoDB::Table\"}"
Output:
