Abstract: Some embodiments provide a method for performing data traffic monitoring. The method processes a packet through a packet processing pipeline that includes multiple stages. At a filtering stage, the method tags the packet with a set of monitoring actions for subsequent stages to perform on the packet based on a determination that the packet matches a particular filter. For each stage of a set of packet processing stages subsequent to the filtering stage, the method (i) executes any monitoring actions specified for the stage to perform on the packet and (ii) sends the packet to a next stage in the packet processing pipeline.

Abstract: Example methods and systems for state consistency monitoring in a network environment are described. In one example, a computer system may identify association chain(s) that associate (a) first state information associated with one or more first network entities residing on a first plane with (b) second state information associated with one or more second network entities residing on a second plane.

Abstract: Some embodiments provide a method of aggregating and providing packet metrics collected during a live packet monitoring session performed for packets matching a specified set of characteristics. The method receives, from one or more computing devices that process packets during the live packet monitoring session, multiple metrics associated with a set of packets matching the specified set of characteristics. Metrics associated with each packet in the set are accompanied by a packet identifier (ID) used to tag the packet by an initial computing device that processed the packet. The method uses the accompanying packet IDs to aggregate the received plurality of metrics. The method provides (i) an aggregated set of session metrics for the set of packets matching the specified set of characteristics during the live packet monitoring session and (ii) individual packet metrics using the packet IDs for at least one packet in the set of packets.

Abstract: An administrator agent and local worker agents are provided in nodes of a distributed system to support dynamic tracing of runtime data. Trace profiles are associated with the nodes on which the local worker agents reside. The local worker agents monitor the runtime data for an error, and the administrator agent adjusts the trace profile(s) in response to the error(s). The administrator agent sends the adjusted trace profile(s) to the local worker agents, so as to enable trace output data of traces performed by the nodes to be increased or decreased.

Abstract: The subject matter described herein provides systems and techniques for the integration of TLVR technology in a vertical power VR module. A multiple-secondary TLVR topology using a controlled leakage inductance in the place of a separate compensation inductor, Lc, may be employed for the vertical power VR module. In addition, the capacitance inside the device to which the TLVR based vertical power VR module supplies power, rather than an output capacitance board, may be used in order to allow the module to be a single layer. Example structures that may include one or more primary windings and/or one or more secondary windings for each of possibly multiple linked phases of the TLVR based module are provided. The windings may be formed using traditional copper windings or printed circuit board (PCB) copper trace winding.
