Another way to use this "at-a-glance" view of network health is to install
Observer on a wireless laptop and watch what happens to the vital signs as
you move the system around your office.
The display below shows the “dial view” of Wireless Vital Signs. Other views
are available by clicking the different view buttons on the tool bar to the left of
the graph display:
In Dial View, vital signs are plotted against 4 axes, each representing one of
the four 802.11b-defined bit rates: 1, 2, 5.5, and 11 Mbits/sec. This allows you
to see the relationships between:
Data Packets (packets with a payload)
Non-Data Packets (control, management, and beacon)
Errors of all types, broken down by type in the table to the right of the graph
display.
