Abstract: Some embodiments provide a method of identifying packet latency in a software defined datacenter (SDDC) that includes a network, several host computers executing several machines, and a set of one or more controllers. At the set of controllers, the method o receives, from a set of host computers, (i) a first set of time values associated with multiple packet processing operations performed on packets sent by a set of machines executing on the set of host computers and (ii) a second set of time values associated with packet transmission between host computers through the SDDC network. The method processes the first and second sets of time values to identify a set of latencies experienced by multiple packets processed and transmitted in the SDDC.

Abstract: Some embodiments provide a method for managing control packet usage within a physical network that implements a plurality of logical networks. The method receives a tunnel monitoring configuration for a logical network. The configuration specifies control packet usage for logical datapaths between logical ports of the logical network. The method maps the logical datapaths to tunnels between host computers that host data compute nodes (DCNs) corresponding to the logical ports. Based on the mappings, the method configures control packet modules executing on the host computers to generate control packets for monitoring the tunnels based on the specified control packet usage.

Abstract: A method inserts a request message in a first encapsulation header that encapsulates a first packet from a data compute node of a first host to form a first encapsulated packet. The first encapsulation header identifies a first address of a first tunnel endpoint in the first host and a second address of a second tunnel endpoint in the second host. The method then sends the first encapsulated packet through a tunnel via the first address of the first tunnel endpoint to the second address of the second tunnel endpoint. If a second encapsulated packet is received at the first tunnel endpoint in the first host from the second tunnel endpoint in the second host and includes a response message, the method records information for the tunnel based on the sending of the request message and the receiving of the response message.
