Fault management is the network management component that deals with
detecting, isolating and correcting network problems. The correct implementation
of fault management system can helps to ensure network functionality. Tools or
platform designed for fault management are called fault management system.
Faults results from malfunction that affect affects delivered of service from the
system. Examples of faults are hardware failure, loss of connectivity and others.
When faults is detected, network component will send message to the network
administrator using protocols called Simple network management protocol
(SNMP) and these faults notification can be viewed in the fault management
system.
The management of faults includes how faults are reported and how faults are
solved once reported. Example of important of fault management is, companies
don’t want downtime for their networks without out having difficult of network
problems because wastes time and money, therefore fault management can be
used to run their network effectively. There are four key elements of fault
management, these are, fault detecting, identify the cause of the fault, solving the
faults, and logging the faults.
, Why fault management is essential?
Fault management is essential for successful network because the growing
dependency of network systems, meaning that downtime of the network
expected to occur. Fault management is mostly important to companies whose
income depend on network systems. For example, banks, telecommunication
companies and others.
Purpose of fault management.
The following are goals of fault management:
First goal of fault management is goal of performance management. Fault
management measure the different aspects network performance in order
to ensure the network operates effectively and service level agreement.
This means that fault management manage network to provide optimum
service to users at better performance. Fault management the performance
level of network devices, in case of performance deterioration, the fault
management system will detect the problem and will identify the cause of
problem.
Second goal of fault management system is goal of configuration
management. Fault management control network and system configuration
information so that if any effects occur on network operation of hardware
and software can be tracked and managed. Fault management provide
regular reports on the network components which help to identify faults
and keep network secure.
Third goal of fault management is security management. Fault
management reduces the chance of fault occurring and keeps network
secure. This manages access to network resources so that sensitive
information cannot be accessed without authorization. For example, when
faults occurs in the system can lead to security effects like network outage
can lead to the loss of data, therefore fault management can reduce the
chance of faults occurring.
