VNet1 uses two ExpressRoute circuits to connect to two on-premises datacenters. You need a dashboard that shows detailed metrics and a visual network topology. Which service should you use?

Azure Monitor Network Insights provides a comprehensive view of network health and performance, including detailed metrics and a visual network topology, making it ideal for monitoring ExpressRoute connections and VNet configurations. A Data Collection Rule (DCR) is used to define what data to collect and where to send it, not for visualization or topology. Azure Virtual Network Watcher offers diagnostic and monitoring tools for VNets, but Network Insights provides a more integrated and visual dashboard for overall network health. Log Analytics is a service for collecting, analyzing, and querying log data, but it doesn't inherently provide the visual network topology or the specific pre-built insights offered by Network Insights.
