You can use Advanced Network Observability to collect the network traffic data of your AKS clusters. It enables a centralized platform for monitoring application and network health. Currently, Prometheus collects metrics, and Grafana can be used to visualize them. Advanced Network Observability also offers the ability to enable Hubble. These capabilities are supported for both Cilium and non-Cilium clusters.
