Chapter 1: Monitor Bandwidth Gauges
Bandwidth gauges work similarly to URL dashboard
gauges, except these gauges solely monitor inbound or
outbound network traffic. Viewing bandwidth gauge activity
of end users helps target areas that are slowing down or
endangering the network.
There are two types of bandwidth gauges: bandwidth
gauges that monitor incoming/outgoing bandwidth for spec-
ified protocols (HTTP, FTP, SMTP, P2P, IM), and bandwidth
gauges that monitor incoming/outgoing bandwidth for spec-
ified port numbers within a given protocol. The latter type of
bandwidth gauge is a subset of the former type of bandwidth
gauge.
NOTE: Unlike URL dashboard gauges, protocol bandwidth
gauges cannot be added to—or removed from—the interface.
However, protocol port numbers can be changed based on end
user utilization in your organization. (See Chapter 2, Edit Port
Settings for information on changing port numbers to be moni-
tored.)
Bandwidth Gauge Components
Incoming/outgoing bandwidth gauges include the following
gauges and ports (TCP and/or UDP) to monitor:

This protocol gauge is comprised of gauges for moni-

• 443 - HTTPS TCP/UDP port used for encrypted trans-
mission over TLS/SSL
