Abstract: For monitoring traffic in a communications network, network protocol requests sent over the network are obtained. The resulting network protocol responses sent over said network are also obtained. It is then determined which request corresponds to which response and each request and corresponding response pair is stored as a single request-response record. Preferably, the time of capture of the request in each record is stored. Moreover, a request lookup key may be created from specific attributes of the request. The requests and responses preferably adhere to the domain name system (DNS) protocol.

Abstract: A method and apparatus for attaching a proximity probe offset to an axis defining a metal probe case and an extension cable extending therefrom. The method and apparatus include a metal interface cup securing the proximity probe therewith; and a metal probe case configured with a first bore extending from one side toward an axis defining a length of the metal probe case. The bore is configured to accept the metal interface cup while leaving a tip of the proximity probe exposed. A bottom surface defining the metal interface cup opposite the tip mates with a first surface defining a closed end of the first bore. The metal probe case is further configured with a second bore extending from a substantially opposite side of the one side. The second bore extends perpendicular from a surface defining the opposite side, wherein only a portion of the second bore intersects the first surface of said first bore creating a through hole into the first bore.
