Using Network Monitor Experts
You can run the Network Monitor Experts supplied with Network Monitor, third-party Experts, or custom Experts that you create yourself. For more information about creating Experts, see the Platform SDK at https://support.microsoft.com/support/smsmgmt/content/sms20sdk.asp.
Table 10.2 lists the functionality of the Experts supplied with Network Monitor.

Example: Measuring network response time
A common user complaint is that a network server or the network is slow. Slow response time problems are often frustrating to solve because it can be difficult to link server performance data to the server responsiveness that users experience at their desktop. Also, it is often difficult to obtain the information you need to determine whether network response times warrant changing configurations or adding additional servers.
Quantifying the speed of the network is simplified by using the Average Server Response Time Expert. This Expert uses Server Message Block, any specified TCP ports (such as HTTP), and any specified IPX sockets to calculate the number of seconds it takes for a server to respond to a client's request for data. You can run the Expert to establish a baseline of average server response times and then compare current responsiveness to historical data. This Expert is also a useful way to quantify server responsiveness under different configurations, such as when an existing Microsoft SQL Server(tm) computer is also configured as a WINS server.
To measure average server response time
Start the Network Monitor Capture window.
To begin capturing frames, on the Capture menu, click Start.
To end the capture and view the summary list of captured frames, on the Capture menu, click Stop and View.
To open the Network Monitor Experts window, on the Tools menu, click Experts, and then click Average Server Response Time Expert.
To configure the Expert, click Configure Expert and specify the TCP ports and IPX sockets that the Expert should monitor.
Click OK, Add to Run List, and then Run Experts.
The average response times of servers measured in the captured data appears in the Event Viewer window.
