Instantiate the Java Serverless Tracer

Warning: Automatic instantiation is compatible with RequestStreamHandler interfaces. All other interfaces require manual instantiation.

RequestStreamHandler is a predefined handler provided by AWS. See AWS documentation for more information.

To automatically instantiate the tracer:

  1. Make your current handler class extend Splunk AppDynamics MonitoredRequestStreamHandler.
  2. Rename your handler class's existing method handleMonitoredRequest.
    The code snippet demonstrates how to instantiate the tracer automatically:
    JAVASCRIPT 
    package <MyTestPackage>;
import com.amazonaws.services.lambda.runtime.Context;
import com.amazonaws.services.lambda.runtime.RequestHandler;
 
//AppDynamics tracer imports
import com.appdynamics.serverless.tracers.aws.api.AppDynamics;
import com.appdynamics.serverless.tracers.aws.api.MonitoredRequestStreamHandler;
import com.appdynamics.serverless.tracers.aws.api.ExitCall;
import com.appdynamics.serverless.tracers.aws.api.Tracer;
import com.appdynamics.serverless.tracers.aws.api.Transaction;

//Keyword extends makes MonitoredRequestStreamHanlder your project's superclass
public class <MaryHadALittleLambda> extends MonitoredRequestStreamHandler {
    
   @Override
	//Change your method to handleMonitoredRequest
    public void handleMonitoredRequest(InputStream input, OutputStream output, Context context) throws IOException {
    	}

        // Your AWS Lambda function code starts here, for example
		int letter = 0;
		while((letter = input.read()) >= 0) {
			output.write(Character.toUpperCase(letter));
        }
    }
