OpenTelemetry Demo: Observability

To improve observability in OpenTelemetry Demo, a developer can follow these steps:

  1. Understand the basics of OpenTelemetry: Before making any changes, it’s essential to have a solid understanding of OpenTelemetry and its components. Review the documentation (https://opentelemetry.io/docs/) and watch related videos (referenced above) to familiarize yourself with the project.

  2. Identify the areas for improvement: Based on the use case and requirements, determine which parts of the OpenTelemetry Demo need improvement in terms of observability. For example, you might want to focus on improving the visibility of specific services or adding more context to the telemetry data.

  3. Implement OpenTelemetry in the identified areas: To improve observability, you’ll need to instrument the codebase with OpenTelemetry. This process involves adding the necessary dependencies, configuring the exporters, and adding the appropriate tracing and metric calls in the code.

  4. Configure the OpenTelemetry Collector: The OpenTelemetry Collector is responsible for collecting and exporting the telemetry data to the desired backends. Configure the collector to process the data from the identified areas and send it to the desired observability platform.

  5. Verify the improvements: After implementing and configuring OpenTelemetry, it’s essential to verify that the improvements have been effective. Use the available tools and dashboards to visualize and analyze the telemetry data and ensure that the desired insights are being gained.

Tests to verify the improvements:

  1. Check that the telemetry data is being collected and exported correctly: Use tools like Prometheus, Grafana, or Jaeger to verify that the telemetry data is being collected and exported as expected.

  2. Verify that the improvements have led to better visibility: Use the observability platform to check that the identified areas have better visibility and that the desired insights can be gained from the telemetry data.

  3. Test the performance improvements: If the goal was to improve performance, run load tests to verify that the application can handle the expected traffic with the new observability setup.

  4. Test the scalability: If the goal was to improve scalability, test the application under heavy load to ensure that it can handle the increased traffic with the new observability setup.

  5. Test the ease of troubleshooting: Use the observability platform to troubleshoot issues and verify that the improvements have made it easier to identify and resolve issues.
