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.
