Overview of Azure Monitor Network Insights for centralized network health, traffic analytics, diagnostics and troubleshooting workflows to monitor, analyze, and resolve Azure networking issues.
Azure Monitor Network Insights gives you a single, centralized view into the health, connectivity, and performance of your Azure networking resources. Instead of opening multiple blades across the Azure Portal, Network Insights consolidates resource health, alerts, and traffic analytics into one dashboard so you can monitor and troubleshoot faster.In this article you’ll learn:
What Network Insights monitors and how it displays resource health.
How traffic analytics and flow logs integrate for traffic visibility.
The built-in diagnostic workflows (Connection Troubleshoot, Packet Capture, Connection Monitor) used for root-cause analysis.
Practical steps to get started and recommendations for telemetry.
From the Monitor overview, expand the Insights section and choose Networks (or select the Network Insights tile).
The Networks view presents grouped resource types (Network Interfaces, NSGs, Private Endpoints, Public IPs, VNets, etc.), alerts, and health signals. Select a resource type to see instance lists and key metrics.
The left pane surfaces grouped resources and active alerts/health signals.
Selecting a resource type (for example, Network Interfaces) opens a list of instances and shows metrics such as bytes/packets sent and received, packet drops, and other telemetry.
Use the workbook icon to open pre-built visualizations for a resource; workbooks provide richer, contextual dashboards without crafting Metrics Explorer queries manually.
If you have VPN Gateways, ExpressRoute, or other cross-prem connectivity, Network Insights integrates with Connection Monitor and Connection Troubleshoot so you can validate paths and measure performance end-to-end.
For security group and traffic visibility, enable NSG flow logs and forward them to a Log Analytics workspace. Traffic Analytics runs on that telemetry to show top talkers, protocols, and traffic trends.
Network Insights also surfaces whether diagnostic features (flow logs, traffic analytics) are enabled and displays related alerts and configuration details.
Packet Capture can collect packets from a VM NIC for deep analysis.
Connection Monitor provides continuous connectivity checks and historical metrics for SLA and trend analysis.
These tools help you determine whether an issue is caused by NSG rules, routing, gateway configuration, or an ExpressRoute/ISP outage.
Network Insights relies on diagnostics collected by Network Watcher and related services. To maximize traffic analytics and workbook insights, enable NSG flow logs and send them to a Log Analytics workspace where Traffic Analytics and workbooks can run.
With this foundation you can use Network Insights as a single-pane view for network health, traffic analysis, and guided troubleshooting. Next, we’ll move on to the final topic.
