1. A method performed at least in part by a network administrator device, the method comprising:
receiving, from an application executing on an end user device, an indication that the application has identified a multicast data flow that is experiencing traffic loss;
transmitting a message to a last hop network device in the multicast data flow to begin monitoring incoming traffic of the multicast data flow, the message including instructions to return a message indicating a first location of the last hop network device based on a determination that the last hop network device is receiving an expected amount of incoming traffic, and to send instructions to an upstream network device to start monitoring incoming traffic of the multicast data flow based on a determination that the last hop network device is not receiving an expected amount of incoming traffic;
based at least in part on receiving a message indicating the first location of the last hop network device, determining that a network fault is occurring at the first location of the last hop network device; and
based at least in part on receiving a message indicating a second location of one of multiple upstream network devices, determining that a network fault is occurring at the second location.
