Kiali has the ability to show traces obtained from Istio. Jaeger collects traces for monitoring and troubleshooting microservices-based distributed systems, and both Istio and Kiali use the data that Jaeger provides. Originally this was done via a separate tab in the UI.
But that turned out to be impractical. So the Kiali team has been working with the Jaeger team on the Jaeger integration. By improving the Jaeger UI components to make them embeddable, there is better integration between a Kiali selection and a Jaeger selection, making it easier to enrich Jaeger with Kiali information.
This enhancement consists of changes in the URL API to personalize the component to be presented from Jaeger UI similar to the Google Maps API. You can view this enhancement in Jaeger in the version 1.8.2 of the project and the related documentation is available here. This enhanced integration between Jaeger and Kiali should be available in the next release of Istio, when Jaeger is updated to version 1.9.
In the meantime we would like to show you what it will look like in future versions.
