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, 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 objects, and the performance metrics of the cluster or a node.
The 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 this panel is one minute.
In the Aggregates tab, the graph displays the top five online aggregates that are nearing capacity, in descending order of used space. You can click the View All link to navigate to the Aggregates inventory page.
The Volumes tab displays the top three SVMs—including destination SVMs for disaster recovery and SVMs in a locked state—that contain the volumes with the highest capacity utilized when you enter a valid value in the Volumes exceeding used capacity of
field. You can click the View All link to view the Volumes dialog box, and then navigate to the Volumes page.
The refresh interval for this panel is 15 minutes.
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 must 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 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 this 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 capacity, from low to high or high to low. You must click the specific bar chart to view more information about the application. 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 this 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 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 this tab is 15 seconds.
