AlliedView NMS Administration Guide (Setting Up Fault Management)
9. Setting Up Fault Management
9.1 Overview
Network Events are entities that represent the various happenings in the network devices. Events can convey general informa-
tion or the current status of the devices in a network.
There are many powerful tools that allow an Administrator to control how managed objects (specific aspects of a device)
report changes in their state. Through parsing and filtering, the Administrator can ensure that any change of state in a device or
set of devices is reported in such a way that users can easily pinpoint the problem (or potential problem).
9.1.1 AlliedView NMS Fault Management Configuration
Note: Although the overall management area is called Fault Management, changes that explicitly result in an
alarm on the Fault Management GUI (table) make up only a part of the overall Fault Management area.
This is explained and shown below.
As a device or the AlliedView NMS undergoes a change, there are various mechanisms that inform the AlliedView NMS that
a change has occurred. These reports pass through various software tools that process these reports and display the changes in
a way that allows the user to quickly understand the nature, severity, and location of the change. Moreover, the user can edit
these software tools to control the filtering and reporting format of these reports.
Figure 9-1 shows the overall configuration of Fault Management, the categories of device (and NMS) changes, the software
tools used by the AlliedView NMS, and the areas where the results are displayed.
