The ProxySG App for Splunk contains several dashboards preconfigured to display the data from Symantec's ProxySG Appliance. The dashboards are left in edit mode to allow users to expand and create new panels to the existing dashboards. The dashboard show the data in views such as General Overviews, Bandwidth Statistics and Security Overviews.
