Systems and methods for monitoring health of Internet Protocol television channels in real-time are described. In one implementation, a monitoring system discovers the distribution paths for multiple channels and proactively pings for component health and audio-visual (AV) quality at different segments of the paths. Health of components and AV quality are displayed in a collapsible tree form of user interface. A channel problem is marked on the tree in a manner that indicates how to expand the tree to trace the problem.
