View the compute topology

The compute topology displays the relationship between clusters and hosts as well as hosts and VMs. You

can view the alarms for the hosts and VMs as well as the CPU usage, memory usage, and storage usage of each cluster. The compute topology visually maps the cloud resources within the management platform and monitors compute resource deployment in real time. Through the topology, you can view the connections and status from data centers down to individual VMs. The compute topology offers the following key values:

• Visual resource distribution—Transforms abstract cloud resources into an intuitive, end-to-end map, from data centers to VMs.

• Unified management & scheduling—As the underlying framework, provides a clear logical topology for unified resource management, intelligent allocation, and efficient scheduling.

• Centralized status monitoring—Displays the health status of resources at each layer (for example, normal, running, hibernated, suspended, shutdown, unknown, and HA exception), enabling at-a-glance global operational awareness.

Restrictions and guidelines

In RBAC mode, only a system administrator or a security administrator can view the compute topology. A system administrator can view the topology, view cloud resource information, and change VM status. A security auditor can only view the topology.
