Using the Amazon X-Ray API with the Amazon CLI
The Amazon CLI lets your access the X-Ray service directly and use the same APIs that the X-Ray console uses to retrieve the service graph and raw traces data. The sample application includes scripts that show how to use these APIs with the Amazon CLI.
Prerequisites
This tutorial uses the Scorekeep sample application and included scripts to generate tracing data and a service map. Follow the instructions in the getting started tutorial to launch the application.
This tutorial uses the Amazon CLI to show basic use of the X-Ray API. The Amazon CLI, available for Windows, Linux, and OS-X, provides command line access to the public APIs for all Amazon Web Services services.
Note
You must verify that your Amazon CLI is configured to the same Region that your Scorekeep sample application was created in.
Scripts included to test the sample application uses cURL
to send traffic to the API and
jq
to parse the output. You can download the jq
executable from stedolan.github.iocurl
executable from
https://curl.haxx.se/download.html
Generate trace data
The web app continues to generate traffic to the API every few seconds while the game is in-progress, but only
generates one type of request. Use the test-api.sh
script to run end to end scenarios and
generate more diverse trace data while you test the API.
To use the test-api.sh
script
Open the Elastic Beanstalk console
. Navigate to the management console for your environment.
-
Copy the environment URL from the page header.
-
Open
bin/test-api.sh
and replace the value for API with your environment's URL.#!/bin/bash API=
scorekeep.9hbtbm23t2
.us-west-2.elasticbeanstalk.com/api -
Run the script to generate traffic to the API.
~/debugger-tutorial$
./bin/test-api.sh

Use the X-Ray API
The Amazon CLI provides commands for all of the API actions that X-Ray provides, including GetServiceGraph
and GetTraceSummaries
. See the Amazon X-Ray API
Reference for more information on all of the supported actions and the data types that they use.
Example bin/service-graph.sh
EPOCH=$(date +%s)
aws xray get-service-graph --start-time $(($EPOCH-600)) --end-time $EPOCH
The script retrieves a service graph for the last 10 minutes.
~/eb-java-scorekeep$ ./bin/service-graph.sh

EPOCH=$(date +%s)
aws xray get-trace-summaries --start-time $(($EPOCH-120)) --end-time $(($EPOCH-60)) --query 'TraceSummaries[*].Http.HttpURL'
The script retrieves the URLs of traces generated between one and two minutes ago.
~/eb-java-scorekeep$ ./bin/trace-urls.sh

The script retrieves full traces generated between one and two minutes ago.
