The Dashboard page has "panels" that display the high level capacity, performance, and security health of the clusters you are monitoring. This page also provides a Management Actions panel that lists fixes that Unified Manager can make to resolve certain events.

Most of the panels also display the number of active events in that category, and the number of new events added over the previous 24 hours. This information helps you decide which clusters you may need to analyze further to resolve events. Clicking on the events displays the top events and provides a link to the Event Management inventory page filtered to show the active events in that category.

At the top of the dashboard you can select whether the panels show information for all monitored clusters ("All Clusters") or for an individual cluster. You can start by viewing the status of all clusters and then drill down to individual clusters when you want to view detailed information.

Some of the panels listed below appear on the dashboard based on your configuration.

Management Actions panel

There are certain issues that Unified Manager can diagnose thoroughly and provide a single resolution. When available, those resolutions are displayed in this panel with a Fix It or Fix All button. You can fix these issues immediately from Unified Manager instead of having to use ONTAP System Manager or the ONTAP CLI. For viewing all the issues, click on See Fixing ONTAP issues directly from Unified Manager for more information.

Capacity panel

When viewing all clusters, this panel displays the physical used capacity (after applying storage efficiency savings) and physical available capacity (not including potential storage efficiency savings) for each cluster, the number of days until the disks are projected to be full, and the data reduction ratio (without Snapshot copies) based on configured ETERNUS AX/HX Series efficiency settings. It also lists the used capacity for any configured cloud tiers. Clicking the bar chart takes you to the Aggregates inventory page for that cluster. Clicking the "Days To Full" text displays a message that identifies the aggregate with the least number of capacity days remaining; click the aggregate name to see more details.

When viewing a single cluster, this panel displays the physical used capacity and physical available capacity for the data aggregates sorted by each individual disk type on the local tier, and for the cloud tier. Clicking the bar chart for a disk type takes you to the Volumes inventory page for the volumes using that disk type.

Performance Capacity panel

When viewing all clusters, this panel displays the performance capacity value for each cluster (averaged over the previous 1 hour) and the number of days until performance capacity reaches the upper limit (based on daily growth rate). Clicking the bar chart takes you to the Nodes inventory page for that cluster. Note that the Nodes inventory page displays the performance capacity averaged over the previous 72 hours. Clicking the "Days To Full" text displays a message that identifies the node with the least number of performance capacity days remaining; click the node name to see more details.

When viewing a single cluster, this panel displays the cluster performance capacity used percentage, total IOPS, and total throughput (MB/s) values, and the number of days until each of these three metrics are anticipated to reach their upper limit.

Workload IOPS panel

When viewing a single cluster, this panel displays the total number workloads that are currently running in a certain range of IOPS, and indicates the number for each disk type when you hover your cursor over the chart.

Workload Performance panel

This panel displays the total number of conforming and non-conforming workloads that are assigned to each Performance Service Level (PSL) policy. It also displays the number of workloads that are not assigned a PSL. Clicking a bar chart takes you to the conforming workloads assigned to that policy in the Workloads page. Clicking the number that follows the bar chart takes you to the conforming and non-conforming workloads assigned to that policy.

Security panel

The Security panel presents the high-level security status for all clusters or a single cluster, depending on your current view. This panel displays:

a list of the security events received in the past 24 hours. Click an event to view the details on the Event details page
the cluster security status (count of compliant and non-compliant clusters)
the storage VM security status (count of compliant and non compliant storage VMs)
the volume encryption status (count of the volumes that are encrypted or not encrypted)
the volume anti-ransomware status (count of volumes with anti-ransomware that are enabled or disabled)

You can click the bar charts of the compliant and non-compliant clusters, storage VMS, encrypted and unencrypted volumes, and volume anti-ransomware status to go to the respective pages and view the security details of the filtered clusters, storage VMs, and volumes.

Compliance is based on the ETERNUS Software Security Hardening Guide for ONTAP 9 Guidelines for Secure Deployment of ONTAP 9. Click the right-arrow at the top of the panel to view security details for all clusters on the Security page. For information, see Viewing detailed security status for clusters and Storage VMs.

Data Protection panel

This panel displays the data protection summary for a single or all the clusters in a data center. It displays the total number of data protection events, MetroCluster events, and number of active events raised in the last 24 hours in ONTAP. Clicking the link from each of these events takes you to the Event details page. You can click the View All link to view all active protection events in the Event Management inventory page. The panel displays:

The number of volumes in a cluster or all the clusters in a data center protected by Snapshot copies.
The number of volumes in a cluster or all the clusters in a data center protected by SnapMirror relationships. For SnapMirror relationships, the volume count at the source cluster is considered.
The number of clusters or all the clusters in a data center protected by MetroCluster configuration over IP or FC.
The number of volume relationships with SnapMirror recovery point objective (RPO) lag based on the lag status.

You can hover your mouse to view the respective counts and legends. You can click the right arrow at the top of the panel to view the details for a single or all the clusters on the Data Protection page. Also, you can click:

The bar charts for unprotected volumes and volumes protected by Snapshot copies to go to the Volumes page and view the details.
The bar charts for the clusters protected or not protected by MetroCluster configuration to go to the Clusters page and view the details.
The bar charts for all relationships to go to the Relationships page, where the details are filtered based on the source cluster.

For more information, see Viewing volume protection status.

Usage Overview panel

When viewing all clusters, you can choose to view clusters sorted by highest IOPS, highest throughput (MB/s), or highest used physical capacity.

When viewing a single cluster, you can choose to view workloads sorted by highest IOPS, highest throughput (MB/s), or highest used logical capacity.
