ITM Process Integrated Traffic Monitoring

Templates are sent to the external data collector after a user-specified number of expired traffic flow entries

and are also re-sent periodically on a user-defined interval. The templates must be re-sent periodically

because UDP is often unreliable, and the collector may discard all traffic flow data lacking valid template

information.

From this point, the chosen external data collector receives and stores the traffic flow entries generated by

ITM. This information can be analyzed and viewed, depending on the capabilities of the chosen external

data collector.
