Remote Network Monitoring
The CenturyStack Hub fully supports RMON Management Group 1, 2, 3,
and 9. Users can setup for RMON Management using Web-Based
Management or SNMP Management. Described here is detailed
information for RMON Group 1, 2, 3, and 9 as well as the operation with
Web-Based Management.
Remote network monitoring (RMON) probe is an instrument that exists
for the purpose of managing a network. The goals of RMON probe are
described as follows:
• Offline Operation
There are sometimes conditions when a management station
will not be in constant contact with its remote monitoring
devices. This is sometimes by design in an attempt to lower
communications costs (especially when communicating over
a WAN or dial up link), or by accident as network failures
affect the communications between the management station
and the probe. For this reason, this MIB allows a probe to be
configured to perform diagnostics and to collect statistics
continuously, even when communication with the manage-
ment station may not be possible or efficient. The probe may
then attempt to notify the management station when an
exceptional condition occurs. Thus, even in circumstances
where communication between the management station and
the probe is not continuous, fault, performance, and configu-
ration information may be continuously accumulated and
communicated to the management station conveniently and
efficiently.
• Proactive Monitoring
Given the resources available on the monitor, it is potentially
helpful for it to continuously run diagnostics and to log
network performance. The monitor is always available at
the onset of any failure. It can notify the management station
of the failure and can store historical statistical information
about the failure. The management station can play this
historical information back in an attempt to perform further
diagnostics of the cause of the problem.
