The network contains several routers and switches.

You need to identify the availability of the switch during the past seven days. The solution must also
ensure that you can review which servers are connected to the switch.
What should you use?

Network Node Dashboard View
A node is any device connected to a network.
Switches and routers are among the most common kinds of nodes you will discover.

The node dashboard provides details on the health of a particular device.
The upper portion of the node dashboard consists of the network vicinity view for that node, as well
as “speedometer” gauges for node availability today, yesterday, in the last week, and in the last
month.
(Periods of time that were not monitored are counted as “available” in the availability statistics, so
newly discovered devices will not appear to have had outages in the gauges.) The lower portion of
the node dashboard includes a list of all interfaces on the node that are being monitored.
From this view, you can manually override the automatic selections of which interfaces are
monitored by SCOM.
Also, by right-clicking on specific interfaces, you can pivot to performance or reporting views that
drill down into the near term or long term history of an interface.
In Figure B, the Interface Packet Analysis report for “PORT 4 on “switch1 during the previous week
appears in a second window.
