Integration of Energy and Systems Management
In an overall systems management environment, power management
is only one aspect of many. This section discusses how to integrate AEM
into the IBM Tivoli systems management platform.
The IBM Tivoli Monitoring tool can monitor the status of your
IT environment. It enables you to monitor your operating systems,
databases, and servers throughout distributed environments through a
flexible, customizable portal. A monitoring agent sits in place to tap the
desired data from the monitored system. With this agent in place, IBM
Tivoli Monitoring can monitor the power, temperature, and CPU usage
of the respective systems. Figure A.3 shows how the components
interact.

Having this entry point into the Tivoli environment enables you to
employ all the well-known features of IBM Tivoli Monitoring and other
tools with which it interacts. You can also add the performance aspect of
energy efficiency.
Optimizing for power and performance might include the following
scenarios:

■ Reprovisioning a server based on the machine’s environmental tem-
perature or overall rack power consumption to another rack in a
cooler area of your data center. On a temperature alert in ITM, you
would trigger the reprovisioning in IBM Tivoli Provisioning
Manager.
