This is an example of a simple, traced Lambda function using the Jaeger Java tracer with SignalFx. See RoulettePlayer.java for the example code.
There are several accepted Java deployment packages for AWS Lambda and you should use the one best suited for your development environment: https://docs.aws.amazon.com/lambda/latest/dg/lambda-java-how-to-create-deployment-package.html In this example we use a standalone .jar that has been generated by Maven. To build this application and create the deployable archive follow these instructions from this document's parent directory:
$ pwd # Confirm this is <your_local_path/tracing-examples/aws-lambda/jaeger-java>
$ mvn package
The resulting ./target/lambda-java-example.jar can be uploaded to S3 or in your browser via the AWS Console
during function creation. Register your handler as example.RoulettePlayer::handleRequest and don't forget
to set the SIGNALFX_INGEST_URL environment variable to point to your Gateway. You should be able verify the
application with the following test event:
{
"queryStringParameters": {
"choice": "00"
}
}
The execution result should succeed with a response similar to:
{
"statusCode": 404,
"body": "{\"TraceId\":\"2296bd21606fc2e4\",\"Result\":\"You Lost! The ball landed on 35.\",\"Choice\":\"00\"}"
}
