A problem of collecting data unnecessarily in an Internet Protocol Television (IPTV) network is, in part, caused by a centralized approach to data collection, whereby data is collected for logical channels, even if not currently streaming to an end node. A method or corresponding apparatus of fault detection according to an example embodiment of the present invention provides for detecting and reporting faults specific to a logical IPTV channel in an IPTV network for logical channels actively streaming to an end user device, such as in response to a "join" request. One or more nodes supporting a logical IPTV channel provide fault indicators, which may be reported to another node or end user. Node(s) in the IPTV network may aggregate and process multiple fault indicators from across a network, thereby enabling diagnosis of specific errors in the IPTV network. Through the use of the method or apparatus, network resources are conserved.
