ChapterRemote Network Monitoring5
The CenturyStack Hub fully supports RMON Management Group 1, 2, 3, and 9. Users can setup for RMON Management using
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.
