Network HUD overview

Applies to: Azure Stack HCI, versions 22H2 and 21H2

Network HUD enables visibility across the network, simplifying operational network diagnostics. It performs real-time analysis of network issues and provides prescriptive alerts or auto-remediation of the issue when possible. These capabilities can increase stability and optimize network performance for workloads running on Azure Stack HCI.

About Network HUD

Diagnosing network issues poses a significant challenge as administrators don't have visibility across the complete solution. The solution can be divided into several areas:

  • Physical Network Switch (ToR), cabling, and NIC
  • Cluster hosts: The HCI OS is installed here.
  • Guest workloads (VMs or containers)

Network HUD can help:

  • Identify misconfiguration on the physical network.
  • Identify operational issues with physical hardware (NICs, cabling, physical switch).
  • Identify and optimize your configuration for increased performance.
  • Auto-remediate some host issues to increase stability and performance.

Network HUD integrates with existing technologies you're already using, like:

  • Network ATC: Network HUD understands the intent of your adapters, ensuring the adapters are operating as expected.

  • Cluster Health: Events from Network HUD are integrated with Cluster Health to ensure your existing tools continue to work. No other dashboards or alerting mechanisms are required.
