The Cluster view dashboard allows the Gluster Administrator to:
- View at-a-glance information about the Gluster cluster that includes health and status information, key performance indicators such as IOPS, throughput, etc, and alerts that can highlight attention to potential issues in the cluster, host, volume, and brick.
- Compare a metric such as IOPS, CPU, Memory, Network Load across hosts within the cluster.
- Compare utilization across bricks within a volume, for example, IOPS, capacity, etc.
