You can monitor your VMware Cloud Director appliance cluster by using the VMware Cloud Director appliance management user interface, the appliance API, or the repmgr open-source tool suite.
You can use the VMware Cloud Director appliance management UI also to view the appliance failover mode. The failover mode indicates whether VMware Cloud Director automatically triggers a database failover if the primary database fails, or the system administrator must initiate the failover manually.
If the failover mode is inconsistent across the nodes, the failover mode is Indeterminate
. The Indeterminate
mode can lead to inconsistent cluster states between the nodes and nodes following an old primary cell. You must diagnose the problem and remedy the situation manually.
