1. A network element, comprising:
one or more processors; and
one or more computer-readable non-transitory storage media coupled to the one or more processors and comprising instructions that, when executed by the one or more processors, cause the network element to perform operations comprising:
allocating a trace identification to a network path trace;
binding the trace identification to a filter policy;
initiating the network path trace within a network by communicating the filter policy and the trace identification to a first node of the network;
receiving network path trace data from a plurality of nodes of the network, wherein:
the plurality of nodes of the network comprises the first node; and
the network path trace data comprises one or more flow identifications; and
generating a trace report for the application using the network path trace data.
