Usage monitoring provides a view into the traffic that is passing through your network. It provides traffic volume information on the applications and application categories being used (determined through Deep Packet Inspection (DPI)), and on the hosts that are using those applications. In addition to traffic monitoring, it also includes the ability to capture packets in order to provide even greater traffic detail.

When you start Usage monitoring, the monitoring point generates traffic flow records in real time and passes them to AppNeta Performance Manager (APM). These records are then collated into groups and classes so that you can easily understand how your network resources are being consumed. You can see how bandwidth at a given location is being devoted to particular applications, hosts, and users. So, for example, if performance at a given location is poor due to high network utilization, Usage monitoring helps identify which applications, hosts, or users are consuming the bandwidth so that you can take steps necessary to resolve the issue.

One of the key differences between Usage monitoring and Delivery and Experience monitoring is that Usage monitoring is passive - it does not generate any test traffic. Because of this, monitoring points have separate ports dedicated to Usage monitoring. Either one port or a pair of bridged ports are required to monitor a link. The cabling method used depends on the capabilities of your switch.
