Bandwidth Consumption per Application and Users for Cisco AVC (10435 / 20435)


This Module utilizes Cisco Application Visibility and Control (AVC) ( NetFlow v9 reporting and provides a list of most active applications and users by traffic. Most active applications and users are reported by Network Device over a time interval. The number of reported top most active applications and users (N) and the observation interval (T, sec) are configurable.

This information is provided per NetFlow exporter.


Parameter NameDescriptionComments
Data Collection Interval, secModule logic execution intervalmin = 10 sec, max = 600 sec, default = 30 sec
Application name listA list of watched applications. If specified, the traffic is reported by specified applications, and all other traffic is summed up under app_name=other. If the list is empty, the traffic is reported by all applications.
List of known server destination port numbersList of server destination ports to be used to determine which host is a client and which is a server. If the list is empty all ports are reportede.g. 53, 80, 443
Share of total traffic reported, %Reported percent of total traffic by application by usere.g. 50 - indicates that all application/user entries consuming 50% of traffic are reported; min = 1%, max = 100%, default = 80%
Report selected applications only (1)Enable/Disable reporting selected apps only (1 - report only apps in the list, 0 - report all apps)default = 0
