History Group
The History Group can be used to create a record of network utilization, packet types, errors and
collisions. You need a historical record of activity to be able to track down intermittent problems.
Historical data can also be used to establish normal baseline activity, which may reveal problems
associated with high traffic levels, broadcast storms, or other unusual events. Historical information
can also be used to predict network growth and plan for expansion before your network becomes too overloaded.
The History Group includes all the tools you need to monitor your network for common errors and overall traffic
rates. When you open the History Group the Control Table screen is displayed as shown below. This table allows
you to add, edit and delete collection entries, or to select a specific index entry and then view the historical data in
numeric or graphic form.
