Packet Size Monitor

The Packet Size Monitor displays sizes of packets on the interfaces on the firewall. You can select from four time periods, ranging from the last 30 seconds to the last 30 days. The Packet Size Monitor can be configured to display inbound traffic, outbound traffic or both for each of the physical interfaces on the appliance.

To configure the Packet Size Monitor:
1
Select one of the following from the View Style drop-down menu:
2
3
In the Direction drop-down menu, select one of the following:
Both – Select for packets traveling both inbound and outbound
Ingress – Select for packets arriving on the interface
Egress – Select for packets departing from the interface

The packets are displayed in the Average Packet Size graph, where the X axis specifies when the packets crossed the interface and the Y axis specifies the average packet size at that time. Ingress packets are displayed in green, and egress packets are displayed in red.
