Monitoring the network subsystem (MCP Series)

The best two performance counters to use when monitoring the network subsystem of a computer are:
  • TCPv4 - Segments/Sec
  • Network Interface - Bytes Total/Sec
TCPv4 - Segments/Sec monitors the number of bytes that pass the network interface using the TCP protocol and Network Interface - Bytes Total/Sec monitors the number of bytes that pass a network interface.
