Product Overview

The architecture of Tivoli Performance Modeler comprised several key components. Data collectors gathered performance metrics from RMF and CMF data sources. The modeling engine processed this data, allowing users to simulate the impact of changes to system resources, including CPU, disk I/O, paging rates, and LPAR definitions.

The reporting module generated reports based on the modeled scenarios, providing insights into resource utilization and performance trends. The GUI was the primary interface for administration, configuration, and user management. The tool used a proprietary database for storing model data and configuration information.

Communication between components was facilitated through internal interfaces. The lack of current support and security updates makes this tool obsolete. Consider migrating to IBM Z Performance and Capacity Analytics or other modern solutions.

The tool's value was in enabling proactive capacity planning and optimizing resource allocation.
