Perimeter Overview

The Perimeter Overview displays charts and interactive visualizations that help you monitor traffic that is entering and leaving your network through connections with external endpoints.

Site Selector

Click the site selector at the top of the page to view data for one or more sites in your environment. View combined traffic across your networks or focus on a single site to help you quickly find device data. The site selector indicates when all or some sites are offline. Because data is not available from offline sites, the charts and device pages associated with offline sites might not show data or might only show limited data. The site selector is only available from a console.
