put-trace-segments

Description

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.

Synopsis

  put-trace-segments
--trace-segment-documents <value>
[--cli-input-json | --cli-input-yaml]
[--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 | --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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

See ‘aws help’ for descriptions of global parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

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": []
}

For more information, see Sending Trace Data to AWS X-Ray in the AWS X-Ray Developer Guide.
