Top Traffic Destinations for Palo Alto Networks (10031 / 20031)


This Module utilizes Palo Alto Networks NetFlow v9 reporting and provides a list of top network bandwidth destinations. Top bandwidth destinations are reported by Network Device and by Destination Port over a time interval. Only TCP/IP and UDP traffic is accounted for. The number of reported top consumers (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 protocol (l4_dst_port) listList of watched layer 4 destination ports. If specified, the traffic is reported by specified ports, and all other traffic is summed up under dest_port=0. If the list is empty, the traffic is reported by all actual destination ports.e.g. 80, 443
N – number of reported hostsTop N (number of reported destinations)min = 0, max = 100000, default = 50 (0 indicates all hosts are reported)
Enable(1) or disable (0) reporting by destination portIf set to 1, enable network traffic monitoring by destination port. If set to 0, report total network traffic as destination port 0 (dest_port=0)default = 0
M – maximum number of destination ports to reportTop number of ports to reportmin = 1, max = 50, default = 10
