Bandwidth Consumption per Application/User for Palo Alto Networks (10035 / 20035)

Description​

This Module utilizes Palo Alto Networks 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.

This Module consolidates NetFlow records over a period of time (Data collection interval) which all have the same combination of the following fields:

  • Application ID
  • Source IP address
  • Destination IP address
  • Source port number, if it is a server destination port number (see below)
  • Destination port number, if it is a server destination port number (see below)
  • Layer 3 protocol

Server destination port: Source port of client hosts is ignored while consolidating NetFlow records. Destination port of server hosts is reported. The Module determines which host is a client and which is a server as follows: a server sends more traffic (bytes) than a client. This logic can be overridden by specifying the list in “List of known server destination port numbers” parameter.

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.

Parameters​

Parameter NameDescriptionComments
Data Collection Interval, secModule logic execution intervalmin = 10 sec, max = 600 sec, default = 30 sec
Application id listA list of watched applications. If specified, the traffic is reported by specified applications, and all other traffic is summed up under app=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 removed or 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

Inputs​

Palo Alto Networks NetFlow v9.
