History Control Entry
RMON can be used to create a record of network utilization, packet types,
errors and collisions. You need a historical record of activity 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. Select “History” then “History
Control Entry” to display the collection items defined in the history control
table.
