Claim 0:
1. A method of identifying latency experienced by a packet sent from a first machine executing on a first computer to a second machine executing on a second computer, the method comprising:
at a third computer:
receiving, from the first computer that executes the first machine that is a source of the packet, a first plurality of time values each associated with a different packet processing operation in a first set of a plurality of packet processing operations performed on the packet on the first computer;
receiving, from the second computer that executes the second machine that is a destination of the packet, a second plurality of time values each associated with a different packet processing operation in a second set of a plurality of packet processing operations performed on the packet on the second computer, wherein at least one of the first and second sets of packet processing operations comprises a particular packet forwarding operation and a particular middlebox service operation and at least two of the received time values are associated with the particular packet forwarding operation and the particular middlebox service operation;
processing the first and second plurality of time values to identify a plurality of latencies experienced by the packet on the first and second computers.
