network management applications and tools have mostly
been reactive in nature. Which means that the management
software can only issue a warning after an unforeseen
event occurs. The event may be a server going down,
a link breaking down, a virus outbreak, extremely high
CPU usage, and sudden reduction in memory levels, among
others. This 'reactive' nature has long been a drawback
for enterprises that look for complete network management.
Lately, most network management software makers have
been working to develop their products in order to make
them more 'proactive'. The idea is to build a network
management system that can let the administrator know
about events in advance, so that they can be prepared
with an alternative plan.
Mitch Young, Regional Manager, ASEAN/SA, Tivoli Software,
IBM Software Group, said that Tivoli management software
now comes with a new functionality called Business Impact
Management (BIM). "At the core, BIM is about managing
availability of business systems and business services.
It's about linking IT infrastructure to business processes.
It allows you to identify in advance an incident which
may affect the continuity of business and lets you figure
out ways to prevent it."
There are four BIM solution sets available for customers
in the form of modules or as a single integrated solution.
The first presents a common user interface. It offers
the ability to create a centralized administrative console
to manage all enterprise applications. Over time it
can be migrated to a portal-based application where
the users can customize the information they want to
view and manage.
The second solution set is about Web technology. It's
about how to leverage the Web and manage dynamic e-business
services. The third solution set is about directory
services. "This allows flexible administration,
and you can administer your network from a remote site,"
The fourth solution set is a data warehouse. Tivoli
creates an open data repository for systems management
information. So all the management information is automatically
put into the data warehouse. "You can create data
marts that will help customers make better decisions
about resource utilization and capacity planning,"
"Tivoli can also put the data warehouse information
into a Service Level Advisor. The Service Level Advisor
looks at the information and uses linear regression
techniques to predict service levels for the future,"
