quickly changing network landscape that contains dozens or
hundreds of separate segments. RMON is the only way to retain
control of the network and analyze applications running at
multi-megabit speeds. It provides the tools you need to implement
either reactive or proactive policies that can keep your network
running based on real-time access to key statistical information.
This switch provides support for mini-RMON which contains the
four key groups required for basic remote monitoring. These
groups include:
Statistics:
Includes all the tools needed to monitor your network
for common errors and overall traffic rates. Information is
provided on bandwidth utilization, peak utilization, packet types,
errors and collisions, as well as the distribution of packet sizes.
History:
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.
Alarms:
Can be set to test data over any specified time interval,
and can monitor absolute or changing values (such as a statistical
counter reaching a specific value, or a statistic changing by a
certain amount over the set interval). Alarms can be set to respond
to either rising or falling thresholds.
Events:
Defines the action to take when an alarm is triggered.
The response to an alarm can include recording the alarm in the
Log Table or sending a message to a trap manager. Note that the
Alarm and Event Groups are used together to record important
events or immediately respond to critical network problems.
