Creating and editing performance graphs

Add and edit performance graphs on the Dashboard.

Graphs can be added containing multiple metrics provided the metrics use the same unit. For example, a graph can contain multiple metrics showing utilization as a percentage, like CPU and disk utilization. Other metrics such as write or read requests for a cluster or the operating system load for a node cannot be added to the utilization graph. Metrics can be added to a graph for a cluster or for one or more nodes.

There are also widgets that display information on Alerts, Cluster Health, and Storage Capacity.
