However, in order for various trace spans to be stitched together for a complete view of the traffic flow, applications must propagate the trace context between incoming and outgoing requests.</p><p>In particular, Istio relies on applications to forward the Envoy-generated request ID, and standard headers. These headers include:</p><ul><li><code>x-request-id</code></li><li><code>traceparent</code></li><li><code>tracestate</code></li></ul><p>Zipkin users must ensure they <a href=https://github.com/openzipkin/b3-propagation>propagate the B3 trace headers</a>.</p><ul><li><code>x-b3-traceid</code></li><li><code>x-b3-spanid</code></li><li><code>x-b3-parentspanid</code></li><li><code>x-b3-sampled</code></li><li><code>x-b3-flags</code></li><li><code>b3</code></li></ul><p>Header propagation may be accomplished through client libraries, such as <a href=https://opentelemetry.io/docs/concepts/context-propagation/>OpenTelemetry</a>. It can also be accomplished manually, as documented in the <a href=/v1.24/docs/tasks/observability/distributed-tracing/overview/#trace-context-propagation>Distributed Tracing task</a>.</p></div><h5 id=how-envoy-based-tracing-works class=question>How does Envoy-based tracing work?</h5><div class=answer><p>For Envoy-based tracing integrations, Envoy (the sidecar proxy) sends tracing information directly to tracing backends on behalf of the applications being proxied.</p><p>Envoy:</p><ul><li>generates request IDs and trace headers (i.e., <code>X-B3-TraceId</code>) for requests as they flow through the proxy</li><li>generates trace spans for each request based on request and response metadata (i.e., response time)</li><li>sends the generated trace spans to the tracing backends</li><li>forwards the trace headers to the proxied application</li></ul><p>Istio supports <a href=/v1.24/docs/tasks/observability/distributed-tracing/opentelemetry/>OpenTelemetry</a> and compatible backends including <a href=/v1.24/docs/tasks/observability/distributed-tracing/jaeger/>Jaeger</a>.

|
|
the outbound requests to the inbound request that caused them. The only way this correlation can be achieved is if the application
|
|
propagates relevant information (i.e. headers) from the inbound request to the outbound requests. Header propagation may be accomplished through client
|
|
libraries or manually. Further discussion is provided in <a href=/v1.24/about/faq/#how-to-support-tracing>What is required for distributed tracing with Istio?</a>.</p></div><h5 id=no-tracing class=question>Why are my requests not being traced?</h5><div class=answer><p>The sampling rate for tracing is set at 1% in the <code>default</code>
|
|
<a href=/v1.24/docs/setup/additional-setup/config-profiles/>configuration profile</a>.
|
|
This means that only 1 out of 100 trace instances captured by Istio will be reported to the tracing backend.

The sampling rate in the <code>demo</code> profile is set to 100%. See
