Xray [BEST] Download Java
Auden Koenig
I have enabled xray loggin and can see the UDP packets being sent logs but seeing nothing in XRay service map or traces, I observed for more than 10 minutes, and sent multiple requests for each of those I used to see the logs from my spring-boot application:
The AWS X-Ray eb-java-scorekeep sample app, available on GitHub, shows the use of the AWS X-Ray SDK to instrument incoming HTTP calls, DynamoDB SDK clients, and HTTP clients. The sample app uses AWS CloudFormation to create DynamoDB tables, compile Java code on instance, and run the X-Ray daemon without any additional configuration.
The sample includes a front-end web app, the API that it calls, and the DynamoDB tables that it uses to store data. Basic instrumentation with filters, plugins, and instrumented AWS SDK clients is shown in the project's xray-gettingstarted branch. This is the branch that you deploy in the getting started tutorial. Because this branch only includes the basics, you can diff it against the master branch to quickly understand the basics.
To support user log-in and AWS SDK for JavaScript use in the browser, the xray-cognito branch adds Amazon Cognito to support user authentication and authorization. With credentials retrieved from Amazon Cognito, the web app also sends trace data to X-Ray to record request information from the client's point of view. The browser client appears as its own node on the trace map, and records additional information, including the URL of the page that the user is viewing, and the user's ID.
Finally, the xray-worker branch adds an instrumented Python Lambda function that runs independently, processing items from an Amazon SQS queue. Scorekeep adds an item to the queue each time a game ends. The Lambda worker, triggered by CloudWatch Events, pulls items from the queue every few minutes and processes them to store game records in Amazon S3 for analysis.
To instrument downstream calls to AWS services with AWS SDK for Java 2.2 and later, you can omit the aws-xray-recorder-sdk-aws-sdk-v2-instrumentor module from your build configuration. Include the aws-xray-recorder-sdk-aws-sdk-v2 module instead, then instrument individual clients by configuring them with a TracingInterceptor.
Sorry if this is 12 years late, but imagine you use xray, right? And you're in a server. You see diamonds on the xray, so you dig to it, but the moment you mine the block in front of the ore, exposing the ore, the diamond ore instantly turns into a copper ore! That is how they prevent xray in servers.
There is a minimal amount of data requirement only for a small portion of time series xrays and these are (should be) handled gracefully. This seems to be a bug in how we do some precision conversions.
Starting with release 2.2.0 of the AWS X-Ray SDK, you can now instrument your AWS SDK clients by including the aws-xray-recorder-sdk-aws-sdk-v2-instrumentor module in your build configuration. This will automatically instrument every AWS SDK service client.
HI,
I have a spring boot application (2.3.1) running in a AWS EC2 instance. I followed AWS documentation for Spring and AOP: -sdk-java-aop-spring.html
I am able to see the traces and service map after I deploy on my AWS EC2 instance.
But when I run my code on my local machine in dev environment(NOT on EC2), it throws an error.

For context, this is happening because the daemon is not running in your dev environment and so the SDK cannot contact it to retrieve centralized sampling rules. Disabling the SDK a known feature request that we have in our backlog, we hope to add support for an environment variable that can disable the SDK soon: -xray-sdk-java/issues/178
