1. A method, comprising:
receiving, by network equipment comprising a processor, a latency diagnostic trigger;
in response to receiving the latency diagnostic trigger, first determining, by the network equipment, whether a latency associated with the latency diagnostic trigger is attributable to a first group of network equipment, wherein the first determining whether the latency is attributable to the first group of network equipment comprises querying a network monitoring system to obtain latency and loss statistics associated with a time window comprising the latency associated with the latency diagnostic trigger;
in response to a result of the first determining being that the latency associated with the latency diagnostic trigger is not attributable to the first group of network equipment, second determining, by the network equipment, whether the latency associated with the latency diagnostic trigger is attributable to a second group of network equipment; and
in response to a result of the second determining being that the latency associated with the latency diagnostic trigger is not attributable to the second group of network equipment, third determining, by the network equipment, that the latency associated with the latency diagnostic trigger is attributable to a third group of network equipment.
