Using Network Monitor to Monitor Bandwidth

Network Monitor is a tool that lets you monitor the data sent and received by the local computer. It provides many capabilities, including enabling users to:

Capture or trace data and filter it based on different attributes.

Monitor throughput based on bytes or frames.

Monitor bandwidth based on the percentage of the network used.

Monitor errors, a possible consequence of an overloaded network.

The Windows NT Server CD includes Network Monitor as an optional Windows NT tool.

Û To install Network Monitor

1. Double-click the Network icon in Control Panel.

2. Click the Services tab, and then click Add.

3. In the Network Service box, double-click Network Monitor Tools and Agent.

Network Monitor comes with a Help file (Netmon.hlp) and a glossary (Nmgloss.hlp). It is also documented in detail in Chapter 10, "Monitoring Your Network," in Microsoft Windows NT Server Concepts and Planning.

For an overall view of bandwidth, use the Network Monitor Frames Per Second and Bytes Per Second status bars. Use the % Network Utilization status bar to view monitor network capacity used. The # Frames Dropped field indicates the number of frames that are not processed because the buffers on the network adapters are full. Frame-dropping occurs when the processor cannot handle the traffic generated by the network.
