What exactly is WinPcap? How does Foglight Transaction Recorder (FTR) use WinPcap? Is WinPcap used during the Recorder or Playback or both functions? Is WinPcap used during playback if, on the intelligent agent, if the Network Statistic Collection and DNS Collection are disabled?"
WinPCap is a third party product bundled with the FTR install. It is used to get network response times by reading network stack. WinPCap is used to monitor the network traffic providing the network byte counts and some timing information when a script is played back.
