Abstract: A comprehensive system for capturing multicast messaging traffic volume and performance metrics across a global inventory of hosts. A single instance of the data capturing and extraction tool may be configured to be implemented across an enterprise's entire inventory of multicast messaging-configured hosts. The data capturing and extraction tool dynamically extracts multicast group addresses and corresponding metrics during the scanning of the captured traffic volume and performance data, thus eliminating the need for manual input of specified multicast group addresses. As a result, presentation of metrics on a per multicast group address basis is made possible for all multicast group addresses extracted during the scanning process. In addition, an efficient means for polling the hosts for traffic volume and performance data is realized by only polling those non-primary and workstation hosts that are currently transmitting or receiving multicast messages.
