The intent of the Summary dashboard is to enable network and storage administrators to focus on particular areas of concern around the health and performance of data center switching. This information is provided as 24-hour snapshots. The functional view of LAN and SAN switching consists of six dynamic portlets that display information in the context of the selected scope by default. The scope can be adjusted in the upper right corner of the window to display focused information that is particular to the managed domain, and offers details of a specific topology or set of topologies that are a part of the data center scope.
The various scopes that are available on the Cisco Data Center Network Manager (DCNM) Web Client are:
From the left menu bar, choose Dashboard > Summary. The Summary window displays six default set panels:
Alarms—Displays events with Critical, Error, and Warning severity alarms.
Data Center—Displays the number of access, spine and leaf devices, and a generic health score for each switch group in the current scope. Devices are aggregated by type within a switch group.
Network Map—Shows populated switch groups that are visible in a user's Role Based Access Control (RBAC) scope on a world map. If you use the scope selector, it limits the set of switch groups displayed. If you use the pop-up option, the map opens in a new tab and can be configured.
The network map dialog box has properties that are different from the Summary dashboard view:
You can click and drag nodes to move them around the map. The map will save their new positions.
You can double click a node to trigger a slider that contains summary inventory information pertaining to a specific switch group.
You can upload an image of your choice as the background to the network map.
Note | Users are prompted to upload an image file with recommended dimension, given their current window size. Reset returns the network map to its default state, resetting the position of the nodes and clearing the custom image. |
Link Traffic—Displays a diagram of inter-switch link and link saturation for transmitting and receiving in the data center.
Audit Log—Displays the accounting log table of DCNM.
Server Status—Displays the DCNM and federation servers' status and the health check status for the components.

The compute dashboard provides you with all the information related to the discovered SAN and LAN hosts. It provides detailed information related to the network, such as I/O traffic, disk latency, CPU, memory statistics, topology, and events about each individual host and virtual machines that are configured on top of the virtual host. The compute dashboard consists of four panels:
Host Enclosures panel—Lists the hosts and their network attributes.
Traffic panel—Provides the I/O statistics, CPU and memory information, and disk latency of individual hosts or virtual machines.
Topology panel—Provides end-to-end topology layout and path information between host enclosures and storage enclosures. The discovered virtual machines are displayed and when you select the virtual machine, the path to the SAN data source is displayed. You can toggle this view to list all data paths.
Event panel—Provides information about events of all of the switch ports that are configured within a specific host enclosure.
