Note that Network Monitor provides for the installation of additional experts. You may have experts other than those listed here installed on your computer. For information about writing custom experts, see the Network Monitor 2.0 Toolkit.

MORE INFORMATION

To use an Expert, click the Tools menu, or right-click a frame in the Summary window. The Experts are summarized below.

Average Server Response Time

The Average Server Response Time expert uses SMB, NCP, any specified TCP port (such as HTTP, Finger, and FTP), and any specified IPX socket to calculate the time. The response time is the number of seconds that it takes for a server to respond to a request from a client for data.

Property Distribution

This expert gathers statistical information for the selected protocol property in the current capture, including the number and percentage of frames.

Protocol Coalesce

The Protocol Coalesce expert merges data from frames that are part of the same transaction. A portion of data sent from one computer can be split into several smaller fragments to be sent over the wire and reassembled at the destination. The Protocol Coalesce expert provides a way to recombine frames.

Protocol Distribution

This expert calculates statistics for the protocols used in a capture.

TCP Retransmit

The TCP Retransmit expert finds all the Transmission Control Protocol (TCP) frames in the capture that have been transmitted to the same computer more than once, and displays the data in the Event Viewer window. Use this data to find computers that are having connection problems with the network.

Top Users

The Top Users expert helps you determine who is using the network, or which computers might be causing a problem such as a broadcast storm.
