Using AWS Distro for OpenTelemetry with Jaeger

AWS Distro for OpenTelemetry (ADOT) is an Amazon Web Services (AWS) distribution of the OpenTelemetry project, which is a set of APIs, libraries, agents, instrumentation, and instrumentation tooling to enable observability in your applications. OpenTelemetry allows you to collect distributed traces and metrics from your applications, providing insights into their performance and behavior.

Jaeger is a popular open-source, end-to-end distributed tracing system that is compatible with OpenTelemetry. It's used to monitor and troubleshoot complex, microservices-based architectures.

Here are the general steps to use AWS Distro for OpenTelemetry with Jaeger:

1. Set Up AWS Distro for OpenTelemetry:Make sure you have an AWS account.Follow the instructions on the AWS Distro for OpenTelemetry documentation to set up the distribution for your specific environment: ADOT Documentation
2. Instrument Your Application:Modify your application code to include the OpenTelemetry instrumentation. This involves adding code snippets or using libraries for the programming language your application is written in. Refer to the OpenTelemetry documentation for language-specific guidance: OpenTelemetry Documentation
3. Configure OpenTelemetry Exporters:Configure your OpenTelemetry instrumentation to export traces and metrics to Jaeger. You can do this by setting up the Jaeger exporter in the OpenTelemetry configuration. The exporter will send the collected data to your Jaeger instance.Sample code (Java) for configuring the Jaeger exporter:java

import io.opentelemetry.exporter.jaeger.JaegerGrpcSpanExporter;
import io.opentelemetry.sdk.trace.export.SpanExporter;

public class MyApplication {
    public static void main(String[] args) {
        // Set up Jaeger exporter
        SpanExporter jaegerExporter =
            JaegerGrpcSpanExporter.builder()
                .setServiceName("my-application")
                .setEndpoint("https://jaeger-collector:14250")
                .build();

        // Configure OpenTelemetry
        OpenTelemetrySdk.builder()
            .setTracerProvider(DefaultTracerProvider.builder()
                .addSpanProcessor(SimpleSpanProcessor.create(jaegerExporter))
                .build())
            .buildAndRegisterGlobal();
    }
}        

4. Set Up Jaeger:

Deploy and configure a Jaeger instance. You can use the official Jaeger Docker image or deploy it in your preferred infrastructure.

Make sure that your OpenTelemetry instrumentation is configured to send traces to the Jaeger collector's endpoint.

5. Verify and Monitor:

1. Start your application and observe the traces in the Jaeger UI. The Jaeger UI provides a visual representation of the traces and can help you identify performance bottlenecks and troubleshoot issues in your distributed system.

By following these steps, you should be able to use AWS Distro for OpenTelemetry to instrument your application and send traces to Jaeger for monitoring and analysis.
