Dell PowerFlex 4.5.x Administration Guide

Displaying system information at a glance

This section introduces the Dashboard, which displays a graphical view of the overall health of the system.

The Dashboard displays at-a-glance information about overall performance, usable capacity, data savings, resources and inventory, resource groups, and alerts.

Overall performance and latency

This section displays graphs that show the overall performance (IOPS and bandwidth) and latency for block and file configurations within the system.

Usable capacity

This section shows the total capacity, along with details about the physical, system, and free capacity.

Data savings

This section provides details about the overall savings and thin provisioning savings.

Resources/inventory

This section shows the number of resources in the current inventory:

VM managers
Nodes
Switches
Protection domains
Storage pools
Volumes
Hosts
File systems
NAS servers

Resource groups

This section displays a graphical representation of the resource groups deployed based on status. The number next to each icon indicates the number of resource groups in a particular state. The resource groups are categorized into the following states:


Tab	Status	Description
Health	Healthy	Green band on the graphic indicates that the resource group is successfully deployed.
	Degraded	Yellow band indicates that resources in a resource group require corrective action, but does not affect overall system health. For example, the firmware version that is installed on a resource in the resource group is not compliant.
	Critical	Red band indicates resource groups that have critical health problems.
	Service Mode	Yellow band indicates that the resource group has been placed in service mode.
Compliance	Compliant	Green band indicates that the resource group is compliant with the target compliance version.
Compliance	Out of compliance	Yellow band indicates that the resource group is non-compliant with the target compliance version.

You can monitor node health by viewing the status of the resource group on the Resource Groups page.

If a resource group is in a yellow (or warning) state, it means that one or more nodes is in a warning or failed state. If a resource group is in a red (or error) state, it indicates that the resource group has fewer than two nodes that are not in a failed state.

To view the status of a failed node component, hover the cursor on the image of the failed component in the resource group.

Alerts

This section lists the current alerts within the system, categorized by severity level:

Critical
Major
Minor
