The Vertica cluster section displays the status of the nodes on which Vertica is configured. The host name, IP address, Status, Free and Used Space on the server are displayed. The statuses displayed are as follows:
Up: indicates that all servers are up.
Down: if at least one server is down in the zone, then based on the replication factor the relevant status is displayed. For example, the status is displayed as down if at least one server is down in a three node cluster with replication factor being 0.
Warning: if at least one server is down in the zone, then based on the replication factor the relevant status is displayed. For example, the status is displayed as warning if at least one server is down in a three node cluster with replication factor being 1.
