Performance metrics of VMware NSX-T nodes
Monitoring VMware NSX-T nodes enables you to take proactive measures and enhance the efficiency of your VMware NSX-T node environment setup. Add a VMware NSX-T Manager to get started with monitoring.
There are two distinct types of VMware NSX-T nodes:
- Edge Node: Provides data on north-south traffic. The Edge Transport Node supplies a consolidated view of the operational health, resource utilization, and availability of the VMware NSX-T Edge node.
- Transport Node: Provides data on east-west traffic. The Host Transport Node supplies a consolidated view of the overlay networking across hosts and the availability of the VMware NSX-T Transport node.
To view your configured VMware NSX-T Node monitor in Site24x7:
- Navigate to Admin > Inventory > Monitors or go to VMware > NSX-T Resources > NSX-T Node.
- Select the desired node to view the monitor health.
Interpreting VMware NSX-T node performance metrics
- Host Summary: This tab helps you quickly assess system status, performance trends, and node activity for north-south traffic handling.
- Interfaces: This tab offers comprehensive visibility into the activity of both physical and virtual Network Interface Cards (NICs) associated with the VMware NSX-T Transport node.
- Tunnels: This tab provides detailed insights of your transport nodes by monitoring tunnel status, source IP addresses, and more to troubleshoot overlay connectivity issues.
- File Systems: This tab provides real-time visibility into the disk partitions and storage utilization of a VMware NSX-T Transport node.
