A network capture element is embodied on a virtual machine, and a utility function is embodied on the actual device, preferably within the virtual machine manager. Both the utility function and the traffic capture element are configured to monitor communication events. To minimize the overhead imposed, the utility function is configured to merely store the time that the event occurred on the actual machine, corresponding to an identifier of the event. The network capture element, on the other hand, performs the time consuming tasks of filtering the communications, selectively storing some or all of the data content of the communications, characterizing the data content, and so on. Instead of storing the virtual time that the communication event occurred at the virtual machine, the network capture element uses the identifier of the communication event to retrieve the actual time that the communication event occurred on the actual machine.
