Details

IBM® Tivoli® Performance Analyzer (ITPA) is a seamless extension to IBM Tivoli Monitoring (ITM).  It extends ITM by adding targeted performance and capacity management capabilities.

ITM itself provides extensive data collection capabilities enabling it to monitor IT performance and availability for system, application and user experience standpoints.   Through the Tivoli Data Warehouse (TDW), ITM enables the integration of historical, near-term and real-time information in a single, customizable user interface.

ITPA leverages the data collected by ITM and applies analytics to produce a normalized performance and capacity metrics across you resources.  These metrics are used in out of the box performance and capacity reports that provide insights into used versus free capacity, over and under utilized resources plus forecasts into future system performance.

In addition ITPA provides a flexible mechanism for defining and deriving you own performance and capacity measures.  It enables the creation of new metrics from collected metrics using flexible mathematical expressions.

The analytics generated by ITPA can be treated just like any other ITM metric. For example they can be used in reporting, combined into status objects and used to create events and situations. Using trending information in reports enables users to determine where the "hot spots" are - which resources are likely to become critical problems the soonest and to focus attention on these systems. The approach enables individual users to be able to remain productive even as the number of components each user is expected to manage continues to grow.
