Dashboard window

The Dashboard window contains multiple panels that provide cumulative at-a-glance information about your system and its performance.

You can use the Dashboard window to view information about system health, performance, overall capacity and network configuration.

Cluster Health
Presents a graphical display of the overall system configuration.

It will display the model of the DM system that is installed including both nodes and all drives that are attached.

By highlighting any of the nodes, you can verify that they are online by looking for the green check box next to the name.

You can also see the overall health at the top of the panel where it says all systems are healthy. Any errors or warnings will also display in that text field.

If you click on the arrow at the top of the window, it will jump to the Cluster > Hardware status screen where you can see a graphical display of the system and the status for any devices.

Capacity
Displays the status of all configured tiers for the system. You will see the currently consumed capacity and the available capacity that has been allocated to a local tier.

If no tiers have been created, it will display the number of spare drives and the option to prepare storage.

If you select the arrow at the top of the window, it will launch the Storage -> Tiers screen and give you the ability to add a local or cloud tier.

This window will also display the overall data reduction for the system.

You can also see if a cloud tier is configured on the system.

A new feature in 9.9.1 is that you will also see the logical capacity consumed by the system.

Network
Displays all of the devices configured.
This includes:
  • Storage VMs

  • Volumes

  • LUNs

  • Hosts

  • Ethernet\FC\NVMe ports

  • FC\NFS\CIFS\iSCSI Interfaces

Clicking on any of these links will launch the corresponding panel

Performance

Displays the average performance metrics, read performance metrics, and write performance metrics of the cluster based on latency, IOPS, and throughput. The average performance metrics is displayed by default. You can click Read or Write to view the read performance metrics or write performance metrics, respectively. You can view the performance metrics of the cluster or a node.

If the information about cluster performance cannot be retrieved from ONTAP, you cannot view the respective graph. In such cases, Storage Manager displays the specific error message.

The refresh interval for the charts in the Performance panel is 15 seconds.
