Displaying and comparing top performer data for entities in a network view

Create a dashboard containing multiple Top Performers widgets to enable you to compare historical poll data across multiple entities and metrics in a selected network view. This dashboard is particularly useful for background investigation and analysis in order to determine how devices and interfaces are performing over time and whether there are any underlying issues.

1. Log in as a user that has the iscadmins role.
2. Create the page, assign it to a location in the navigation, and specify the roles that users need to view the page.
   The default location is Default, and in this task it is assumed that this default location is used. If you use a different location, then substitute your chosen location wherever you see the location Default used in this task.
3. Add the Network Views widget to the page.
4. Add two Top Performers widgets to the page.
   Note: Adding two Top Performers widgets enables you to perform basic comparisons, such as displaying metric traces on the same device or interface over two different time periods. You can add more than two Top Performers widgets, and this will provide the ability to perform comparisons across a wider range of data; for example, adding four Top Performers widgets enables you to display metric traces on the same device or interface over four different time periods.
5. Click Save and Exit to save the page.
   Note: This page does not requires any wires. The Network Views widget automatically broadcasts the NodeClickedOn event, and the other widgets automatically subscribe to this event and update their data accordingly.
