OceanBase Cloud Platform (OCP) provides the tenant topology feature. Based on the topology of a tenant, you can view the cluster, zone, and OBServer node where the tenant resides.
Log on to the console. In the left-side navigation pane, click Tenants and click the name of the tenant that you want to view in the Tenants list to go to the Overview page of the tenant. In the left-side navigation pane, click Topology to view details of the tenant topology.
The topology of a tenant consists of three layers:
The first layer, which indicates the cluster.
The second layer, which indicates the zones.
The third layer, which indicates the OBServer nodes.
