Minimally, you must provide `spec.external_services.tracing.internal_url` to
enable Kiali features that use distributed tracing data. However, Kiali can
provide contextual links that users can use to jump to the Jaeger console to
inspect tracing data more in depth. For these links to be available you need to

A common mistake is to forget the `/jaeger` suffix, which is often used in Jaeger deployments.

On the Application detail page, the Traces tab might redirect to Jaeger via an external link instead of showing the Kiali Tracing view. It happens when you have the `url` field configured, but not `in_cluster_url`, which means the Kiali backend will not be able to connect to Jaeger.
