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 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 for monitoring a multi-tenant network management system deployed in a public cloud to manage groups of datacenters. Each respective datacenter group includes one or more datacenters of a respective tenant that defines the datacenter group. For each datacenter group of a set of datacenter groups managed by the multi-network management system, the method deploys a set of network management service instances in the cloud specified by the tenant for the datacenter group. Each of the network management service instances provides a specified service to the datacenters of the datacenter group. For each datacenter group, the method deploys a metric monitoring service instance in the cloud for the datacenter group. The metric monitoring service instance is for collecting and analyzing metrics from services belonging to each of the network management service instances deployed for the datacenter group.

Abstract: Some embodiments provide a method for monitoring a multi-tenant network management system deployed in a cloud to manage groups of datacenters. The network management system includes multiple groups of service instances. For each respective group of service instances deployed in the cloud to manage a respective datacenter group, the method deploys a metrics collection agent within each service instance of the group of service instances to collect metrics from services of the service instance and provide the collected metrics to a metric monitoring service instance of the group of service instances. For each respective group of service instances, the method deploys a metrics collection manager within the metric monitoring service instance of the group of service instances. The metrics collection manager is for configuring each of the metrics collection agents deployed within the service instances of the group of service instances.

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.
