How does distributed tracing work with Istio?	0

Istio integrates with distributed tracing systems using Envoy-based tracing. With Envoy-based tracing integration, applications are responsible for forwarding tracing headers for subsequent outgoing requests.

You can find additional information in the Istio Distributed Tracing (Jaeger, Lightstep, Zipkin) Tasks and in the Envoy tracing docs.
