Statistics
Statistics
The first view into statistics provides the overall network
health. The operator can drill down into the statistics to get
more and more detailed information. Some of the more detailed
information is gathered by software that may not have enough
bandwidth to process 100% of the frames. So a value is
presented for the percent of frames processed in these cases.
Overall Statistics
The current and maximum values of each statistic are
displayed. Graphs of the each statistic are also displayed in
strip charts. The interval at which the graph is updated is
programmable so that the graph can cover the last 5 minutes in
detail up to the last 24 hours with less details. The operator can
obtain more information about any of these statistics by
selecting it.
Utilization Utilization values are displayed as percent of total
network bandwidth. Pressing this statistic switches to a list of
Top Transmitters.
Unicasts The number of unicast frames or the percent of the
utilization used up by unicast frames. Pressing this statistic
switches to a list of Top Unicast Transmitters.
Multicasts The number of multicast frames or the percent of
the utilization used up by broadcast frames. Pressing this
statistic switches to a list of Top Multicast Transmitters.
Pressing any of the Top Transmitters brings up the Station
Detail screen for that station.
