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: Some embodiments provide a method of identifying packet latency in a software defined datacenter (SDDC) that includes a network and multiple host computers executing multiple machines. At a first host computer, the method identifies and stores (i) multiple time values associated with several packet processing operations performed on a particular packet sent by a first machine executing on the first host computer, and (ii) a time value associated with packet transmission through the SDDC network from the first host computer to a second host computer that is a destination of the particular packet. The method provides the stored time values to a set of one or more controllers to process to identify multiple latencies experienced by multiple packets processed in the SDDC.

Abstract: Some embodiments of the invention provide a method for performing dynamic packet tracing in a network that includes a network controller and multiple host computers, each host computer including a set of packet processing stages for processing packet flows in the network. The method is performed for each packet processing stage in the set of packet processing stages at a particular host computer in the network. The method provides to the packet processing stage a set of trace instructions for use in generating a set of trace data when processing packets belonging to a particular packet flow for which a packet tracing operation has been defined. The method receives from the packet processing stage the set of trace data generated during processing of a packet belonging to the particular packet flow. The method determines that the set of trace instructions should be provided to a next packet processing stage in the set of packet processing stages and provides the set of trace instructions to the next packet processing stage.
