Kiali vs OpenCensus: What are the differences?
Developers describe Kiali as "Service mesh observability and configuration". It is an observability console for Istio with service mesh configuration capabilities. It helps you to understand the structure of your service mesh by inferring the topology, and also provides the health of your mesh. On the other hand, OpenCensus is detailed as "A single distribution of libraries that automatically collect traces and send them to any backend". It is a set of libraries for various languages that allow you to collect application metrics and distributed traces, then transfer the data to a backend of your choice in real time. This data can be analyzed by developers and admins to understand the health of the application and debug problems.
Kiali and OpenCensus belong to "Monitoring Tools" category of the tech stack.
