The Multicast Manager allows users to set thresholds on traffic flowing in multicast groups that generate notifications when the traffic exceeds or drops below the threshold.

Thresholds can be set on polled values for traffic at each multicast service in the distribution tree for a multicast group. It is possible to set both maximum value and minimum value thresholds, and to have different threshold values apply to different multicast groups, as needed. When a threshold value is breached, a notification is raised and sent to the Global Manager. Information on thresholds is provided in “About the Polling and Thresholds Console”.
