The Current State of OTEL Tracing

Introduction

OpenTelemetry (OTEL) is a set of APIs and SDKs for collecting and generating telemetry data (metrics, logs, and traces) for distributed applications. It provides a standardized way to instrument applications and collect data that can be used for monitoring, debugging, and performance optimization. However, to effectively use OTEL tracing, it is essential to have detailed information about each message. In this article, we will discuss the importance of adding more details to OTEL traces and how it can improve the overall tracing experience.

The Current State of OTEL Tracing

OTEL tracing provides a robust way to collect and analyze distributed application data. It supports various formats, including JSON and Protocol Buffers, and can be used with popular observability tools like Prometheus, Grafana, and Jaeger. However, the current implementation of OTEL tracing may not provide enough details about each message, making it challenging to understand the flow of data through the application.

The Need for More Details in OTEL Traces

To effectively use OTEL tracing, it is crucial to have detailed information about each message. This includes attributes like message type, payload size, and any relevant metadata. With this information, developers can better understand the flow of data through the application, identify performance bottlenecks, and optimize the system for better performance.

Benefits of Adding More Details to OTEL Traces

Adding more details to OTEL traces can bring several benefits, including:

Improved debugging: With more information about each message, developers can quickly identify the source of issues and debug the application more efficiently.
Enhanced performance optimization: By understanding the flow of data through the application, developers can identify performance bottlenecks and optimize the system for better performance.
Better monitoring: With more details about each message, developers can create more effective monitoring dashboards and alerts, enabling them to respond quickly to issues.

Proposed Solution

To address the need for more details in OTEL traces, we propose adding the following attributes to the OTEL traces emitted by the runtime:

Message type: The type of message being sent, such as request, response, or event.
Payload size: The size of the message payload in bytes.
Metadata: Any relevant metadata associated with the message, such as user ID or session ID.

Implementation

To implement the proposed solution, we will need to modify the OTEL tracing code to include the additional attributes. This will involve updating the OTEL SDKs to emit the new attributes and modifying the observability tools to support the additional data.

Example Use Case

Here is an example of how the additional attributes can be used in a real-world scenario:

Suppose we have an e-commerce application that sends a request to a payment gateway to process a transaction. The OTEL trace for this request might include the following attributes:

Message type: Request
Payload size: 1024 bytes
Metadata: User ID: 12345, Session ID: abcdef

With this information, the developer can quickly identify the source of issues and debug the application more efficiently.

Conclusion

In conclusion, adding more details to OTEL traces can significantly improve the overall tracing experience. By including attributes like message type, payload size, and metadata, developers can better understand the flow of data through the application, identify performance bottlenecks, and optimize the system for better performance. We propose adding the following attributes to the OTEL traces emitted by the runtime and provide an example use case to illustrate the benefits of this approach.

Future Work

Future work will involve implementing the proposed solution and testing it with real-world applications. We will also need to modify the observability tools to support the additional data and provide feedback to the OTEL community on the effectiveness of this approach.
