Interpreting Device Status
The Status - Overview page for the hubs displays the Performance Gauges and
any alerts that have occurred. For switching hubs, the Status - Overview page
displays gauges by segment instead of by attribute.
See the chapter Alerts for more information on the Alert Log.
Reading the Performance Gauges
The performance gauges display statistical information about the selected
device. By looking at the gauges, you can quickly determine if there are
problems with the network utilization, collisions, the number of broadcasts
per second, or the number of error packets. The gauges are refreshed every
five seconds.
