put-trace-segments

Description

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 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.

Synopsis

  put-trace-segments
--trace-segment-documents <value>
[--cli-input-json <value>]
[--generate-cli-skeleton <value>]

Options

--trace-segment-documents (list)

A string containing a JSON document defining one or more segments or subsegments.

(string)

Syntax:

"string" "string" ...

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. 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.

Examples

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:

{
    "UnprocessedTraceSegments": []
}
