Logging with istio
By default, you don't have a logging system on Istio. I mean, besides the native logging of Kubernetes.
Zipkin and Jaeger are tracing systems, meaning for latency, not for logging.
You can definitely get this info through Istio components, but you will have to set it up first. I found this articles; in Istio website about how to collect logs. I would say Fluentd + Elasticsearch would give you something as powerful as you need. Unfortunately I don't have any examples.
