Collected Data

Traffix Manager collects and correlates data from stand-alone and
embedded

RMON-1 and RMON-2 agents

, from both 3Com and other

vendors. This data provides a complete picture of enterprise network
traffic for performance management and trend analysis.

At scheduled intervals, Traffix Manager’s Collector process uploads the
collected traffic data, processes the contents and stores the results in a
relational database.
