1. A method comprising:
receiving a first protocol data unit (PDU) on a first interface of a plurality of interfaces of a network device, wherein the first interface is one of the plurality of interfaces of the network device instrumented to capture PDUs, wherein the network device comprises a wireless access point;
determining a type of the first PDU, wherein the type of the first PDU corresponds to a communication protocol with which the first PDU is associated;
determining if the first PDU should be captured based on a type of the first PDU and a type of the first interface on which the first PDU was received;
based on determining that the first PDU should be captured, writing a copy of the first PDU in a PDU capture file;
associating information about a network environment in which the network device operates with the PDU capture file as metadata; and
based on determining that an upload criterion has been satisfied, uploading the PDU capture file having the metadata associated therewith to a server.
