The Sniffer Portable Professional monitor stores statistical
measurements and calculations about your network traffic, providing an
accurate picture of network activity in real time. It can generate alarms
to notify you when errors are detected and can save historical records of
network activity that you can use later for traffic and fault analysis.
Monitoring features provide the following information:
Network load statistics, including the number of frames/bytes of
network traffic per time interval, the percentage of utilization, and
broadcast and multicast counts.
Protocol use statistics.
Application response time statistics for upper layer protocols.
Individual station and conversation-pair traffic statistics.
Packet size distribution statistics.
The data collected by the monitor can help you find traffic overloads,
troubleshoot bottlenecks, and locate faulty equipment. The data can also
be an important factor in deciding how to allocate your company’s
resources for network maintenance and upgrades.
