In this chapter, you have learned how to configure new metrics collection using Mixer's attribute vocabulary for microservices. You have gone through the Prometheus pull model for data scrapping from the Istio control plane, as well as from Envoy sidecar proxies. You have also explored Grafana for visualizing collected and aggregated data and service mesh observability, looked at animation through Kiali, and looked at distributed tracing using Jaeger.
In this section of the book, we've covered traffic management, security, policy, and telemetry features of Istio in detail. In the next section of this book, we will cover the Linkerd service mesh.
