NetSight Element Manager provides valuable performance statistics from the
Network, Management Station, and Port levels. The statistics windows include
ring status information, beacon statistics, error counts, timer statistics, frame size
and protocol statistics, and performance graphs.
Statistics Window Features
Many of the token ring statistics windows allow you to measure and view
statistics according to different scales, and set a time interval after which statistics
are automatically updated. The following sections detail these features.
Setting Total, Delta, or Cumulative Counts
By using the radio buttons located at the bottom of the Network, TR Management
Station, and Station (Port) Statistics windows, you can change the time period
during which the statistics shown in the window are collected. An example of this
group of radio buttons is shown in
