AppVis™
Overview
At a glance, you can quickly identify the applications running on your network with recognised logos for each one. This page shows details of all applications discovered in or beneath the selected folder or location in the Network Explorer tree. You can also group applications and filter the display to show only groups of most interest. By default the top 10 items by highest usage are shown. Each discovered application shows:
the application logo, name and category
the total number of locations where the application has been seen
dates when it was first and last seen
DSCP values and classes used, and assigned groups
a usage figure
plus a breakdown of all locations and classes
Refer to our Classic Help & Support Centre AppVis page
