Не удалось увидеть в skywalking ui данные из istio показателей.
Используйте приведенное ниже руководство для установки istio и skywalking бэкенда в Kubernetes: https://github.com/apache/skywalking/tree/master/docs/en/setup/istio. Сделал все шаги в руководстве и развернул приложение. Развернутое приложение — это пример book app из istio. Можно видеть трассировки в Jaeger и работает хорошо, но не видит метрики istio в skywalking ui.
Как я могу предоставить метрики от istio до skywalking ui или что мне нужно настроить, чтобы метрики от istio пришли к skywalking ui.

каким-то образом мне не удалось подключиться к моему бэкэнду skywalking, проблема была с именем и пространством имен, но все еще получаю ошибку, но теперь бэкэнд skywalking получает данные, но пользовательский интерфейс не обновляется. Istio телеметрия:
rpc error: code = Unavailable desc = upstream connect error or disconnect/reset before headers. reset reason: connection failure
