Traffic Graphs

Real time traffic graphs drawn with JavaScript using NVD3 are available which update continually. These graphs can be viewed at Status > Traffic Graph, and an example of the graph can be found in Figure Example LAN Graph.

These traffic graphs show interface traffic as it happens, and give a clear view of what is happening “now” rather than relying on averaged data from the RRD graphs which are better for long-term views.

Example LAN Graph

Only one interface is visible at a time, and this interface can be changed using the Interface drop-down list. Once an interface is chosen, the page will automatically refresh and start displaying the new graph.

Similar style traffic graphs can also be viewed on the Dashboard by adding the Traffic Graphs widget. Using the widget, multiple traffic graphs can be displayed simultaneously.

A table containing momentary glimpses of data being transferring from specific IP addresses is also displayed next to the traffic graph. These are limited to only displaying briefly, so ongoing transfers are more likely to show up than quick connections. Also, only connection from within that interface’s primary subnet will be shown.

The display of the graph and table can be controlled using the following options:

Interface:

The firewall interface to use as the traffic source for the graph and the table.

Sort By:

Selects the sort order of the graph, either Bandwidth In or Bandwidth Out.

Filter:

Selects which type of hosts to display in the table

Local:

Shows only IP addresses within the interface network

Remote:

Shows only IP addresses that are not within the interface network

All:

Shows all IP addresses, inside and outside the interface network

Display:

Controls the display of the Host IP column using one of the following choices:

IP Address:

The IP address of the host.

Host Name:

The short hostname that corresponds to the IP address, as listed in DHCP static mappings, DNS Resolver host overrides, or DNS Forwarder host overrides.

Description:

The description that corresponds to the IP address, as listed in DHCP static mappings, DNS Resolver host overrides, or DNS Forwarder host overrides.

FQDN:

The fully qualified domain name that corresponds to the IP address, as listed in DHCP static mappings, DNS Resolver host overrides, or DNS Forwarder host overrides.
