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 important alerts and notifications, the efficiency and capacity of aggregates and volumes, the nodes that are available in a cluster, the status of the nodes in a high-availability (HA) pair, the most active applications and objects, and the performance metrics of a cluster or a node.
The Alerts and Notifications panel displays up to three alerts and notifications beyond which a View-All link is displayed. You can click the View-All link to view more information about the alerts and notifications.
The refresh interval for the Alerts and Notifications panel is one minute.
The Capacity tab displays the top online aggregates that are nearing capacity, in descending order of used space.
The Capacity tab provides a link to the number of volumes with the highest capacity utilized when you enter a valid value in the Volumes exceeding used capacity of field. It also displays the amount of inactive (cold) data available in the cluster.
The refresh interval for the Health Overview panel is 15 minutes.
You can navigate to the Volumes window to view the volumes that do not have a protection relationship.
The Protection tab also displays the top five SVMs that have the highest number of volumes that are missing protection relationships.
Displays a pictorial representation of the number and names of the nodes that are available in the cluster, and the status of the nodes that are in an HA pair. You should position the cursor over the pictorial representation of the nodes to view the status of the nodes in an HA pair.
You can view more information about all of the nodes by using the Nodes link. You can also click the pictorial representation to view the model of the nodes and the number of aggregates, storage pools, shelves, and disks that are available in the nodes. You can manage the nodes by using the Manage Nodes link. You can manage the nodes in an HA pair by using the Manage HA link.
The refresh interval for the Nodes panel is 15 minutes.
The Applications tab displays information about the top five applications of the cluster. You can view the top five applications based on either IOPS (from low to high or from high to low) or capacity (from low to high or from high to low). You should click the specific bar chart to view more information about the application. For capacity, the total space, used space, and available space are displayed, and for IOPS, the IOPS details are displayed. You can click View details to open the Applications window of the specific application.
The Objects tab displays information about the top five active clients and files in the cluster. You can view the top five active clients and files based on IOPS or throughput.
The refresh interval for the Applications and Objects panel is one minute.
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, System Manager displays the specific error message.
The refresh interval for the charts in the Performance panel is 15 seconds.
