<p><strong>Tracing</strong> is a critical tool that allows developers to visualize and understand the flow of
requests in an AI application. With tracing, you can capture a detailed view of how requests propagate
through various services and components, which is crucial for <strong>debugging</strong>, <strong>performance optimization</strong>,
and understanding complex AI agent architectures like Co-pilots.</p>
<p><strong>Arch</strong> propagates trace context using the W3C Trace Context standard, specifically through the
<codeclass="docutils literal notranslate"><spanclass="pre">traceparent</span></code> header. This allows each component in the system to record its part of the request
flow, enabling <strong>end-to-end tracing</strong> across the entire application. By using OpenTelemetry, Arch ensures
that developers can capture this trace data consistently and in a format compatible with various observability

<p>To integrate AI tracing, your application needs to follow a few simple steps. The steps
below are very common practice, and not unique to Arch, when you reading tracing headers and export
<li><p>Read the <codeclass="docutils literal notranslate"><spanclass="pre">traceparent</span></code> header from incoming requests.</p></li>
<li><p>Start new spans as children of the extracted context.</p></li>
<li><p>Include the <codeclass="docutils literal notranslate"><spanclass="pre">traceparent</span></code> header in outbound requests to propagate trace context.</p></li>
<li><p>Send tracing data to a collector or tracing backend to export spans</p></li>

<p>By leveraging the <codeclass="docutils literal notranslate"><spanclass="pre">traceparent</span></code> header for trace context propagation, Arch enables developers to implement
tracing efficiently. This approach simplifies the process of collecting and analyzing tracing data in common
tools like AWS X-Ray and Datadog, enhancing observability and facilitating faster debugging and optimization.</p>
