Details

The new Tivoli® Data Warehouse (TDW), an optional component of the Tivoli Enterprise Portal (TEP) platform and the next warehousing step beyond TDW 1.3, stores metric information relating to the current capabilities and capacity of IT assets. Metrics captured from the various Tivoli Enterprise Management Agents (TEMA) are stored in the Warehouse. This information can be key information such as percent CPU busy overtime. This information can be obtained for business applications in production or in a test environment as well as for IT infrastructure systems.

As seen in the diagram TDW can be utilized to control which metrics are collected and the frequency with which those metrics are collected. Thus availability and capacity information can be ascertained by IT through key TEMA metrics and at the desired frequency. If the TEMA doesn't provide the metrics required, a Universal Agent can be customized to collect available information for historical analysis.

If a known workload is targeted for a system this historical data can be utilized by IT to discern if there is actually capacity to take on the work on the system. Also the historical availability data can be utilized to discern if the targeted availability metric has been met historically or if additional measures must be implemented to achieve the desired availability target.

Once this metric information is collected the customer can utilize TEP or other relational analysis reporting tools to retrieve data from TDW that displays historical availability and capacity information.

Information about available the available monitoring agents and their associated metrics can be obtained from IBM® monitoring products. See http://www.ibm.com/software/tivoli/products/monitor/.
