Chapter 32: Traffic Monitoring

ZoneRanger, in combination with Ranger Gateway, can receive and proxy different protocols from
devices in the network to management applications. Due to the transparent nature of a ZoneRanger
deployment, it can be difficult to determine how much traffic is being received and proxied through a
particular ZoneRanger and Ranger Gateway. Also, it can be difficult to determine if a particular device
is frequently sending information to a ZoneRanger or is frequently being queried by the ZoneRanger.
By default, ZoneRanger and Ranger Gateway will monitor the traffic they are receiving and proxying
over the past configured interval for each Traffic Type (SNMP Trap, Syslog, ICMP, SNMP, etc). During
the configured measurement interval on the ZoneRanger and the Ranger Gateway, the total amount of
traffic for each Traffic Type will be measured. The amount of traffic will also be logged if Traffic
logging is enabled to Short. On the ZoneRanger, the amount of traffic for each Traffic Type for each IP
address will also be measured. The amount of traffic will also be logged if Traffic logging is enabled to
Full. On the Ranger Gateway, the amount of traffic for each Traffic Type to each joined ZoneRanger
will also be measured. The amount of traffic will also be logged if Traffic logging is enabled to Full.
On the ZoneRanger web interface View > Traffic Information page, overall received traffic and proxy
traffic as well as traffic per IP address may be viewed.
The ZoneRanger and Ranger Gateway may be configured to check thresholds for each Traffic Type over
the measurement interval. If a threshold is exceeded, a message will be logged in the system log file and
if enabled, a SNMP trap notification will also be sent. On the ZoneRanger, thresholds may be set for the
overall Traffic Type and on a per IP address basis. On the Ranger Gateway, thresholds may be set for
the overall Traffic Type and on a per ZoneRanger basis.
