2.4.2. Azure Monitor Network Insights
Network Insights provides a dashboard view of network health, dependencies, and connectivity across all your Azure networking resources.
Capabilities:
- Health view of all network resources
- Connectivity status between resources
- Network topology visualization
- Integration with Azure Monitor metrics and logs
When to Use:
- Get overview of entire network health
- Identify failed or degraded components
- Track metrics across multiple resources
How it differs from Network Watcher. Network Watcher hands you instruments for one question at a time — is this flow allowed, what is the next hop, capture these packets. Network Insights starts from the opposite end: it renders every networking resource in the subscription, colour-coded by health, with the dependencies between them drawn in. You use it to find which component to investigate, then drop into Network Watcher to investigate it.
💡 First Principle: Insights answers "where should I be looking?" and Network Watcher answers "what is happening here?" A scenario that starts with a vague symptom across many resources is pointing at the first; one that names two endpoints and a failing connection is pointing at the second.
