OpenTelemetry traces
Also written: OTel traces
Records of how software actions flow through a system, used for debugging and performance monitoring.
OpenTelemetry traces are like a detailed travel log for a software request. When you ask an AI model a question, your request doesn't just go to one place. It might go through several different services or steps to get processed. A trace records every single step, showing where the request went, how long each step took, and what happened.
Think of it like tracking a package. The trace shows you when it was packed, when it left the warehouse, when it arrived at a sorting facility, and when it was delivered. For software, this helps developers understand if a request is slow because one specific step is taking too long, or if there's an error somewhere in the process.
OpenTelemetry traces are a standardized way to represent the end-to-end journey of a request as it propagates through distributed systems. A trace is composed of spans, where each span represents a unit of work (like a function call or an API request) with a start time, duration, and associated metadata. Traces enable observability by providing detailed insights into request latency, error sources, and system behavior, crucial for debugging and performance optimization in complex microservice architectures.
OpenTelemetry traces are becoming more relevant as frontier AI labs build increasingly complex, distributed systems. Understanding the flow of requests and operations through these systems, as captured by traces, is crucial for debugging, performance optimization, and ensuring the reliability of AI services.

OpenTelemetry is an open-source observability framework, a CNCF project that evolved from the merging of OpenTracing and OpenCensus. It aims to standardize the generation and collection of telemetry data. Source ↗
You can explore OpenTelemetry traces by using tools like Jaeger or Zipkin. If you are running a local application that has OpenTelemetry instrumentation, you can send traces to one of these backends and visualize the request flow. Look for a trace that shows a slow or failed request to understand how traces help pinpoint issues.

Questions people ask
- What is a span in OpenTelemetry?
- A span represents a single operation or unit of work within a trace, such as an incoming HTTP request or a database query. It has a start time, duration, and can contain metadata.
- How do traces help with performance?
- Traces show the latency of each step in a request's journey. By visualizing this, developers can identify bottlenecks and optimize slow parts of the system.
