Most likely your traditional system wasn't designed for the ways your network is used today. It only lets you see the devices you own, not your entire, end-to-end network paths. To manage properly, you need to be able to see through the cloud and monitor the health of individual paths.
PathView's and AppCritical's network monitoring capabilities give you direct management across your entire extended network. They take a continuous view path performance, covering not only your network, but also those of your carriers, service providers, partners and customers.
