Performance Management - What Is It?
Performance Management provides the capabilities for customers to understand and manage the performance of their computing environments.
- Real-time Monitoring
- History/Trends of Performance/Capacity
- Capacity Planning
- Performance Tuning Controls
- Performance Problem Isolation
- Workload Balancing
- Application
- "Design for Performance" Tools
To support these capabilities, products and tools, data collection facilities, and instrumentation are required.
Size and complexity of customer computing environments - client/server, cooperative and distributed applications, distributed data, local and wide area networks, Web/intranet/internet, third-party and home-grown applications, heterogeneous computing resources - all place ongoing demands on the capabilities for understanding and managing performance.
Technologies supporting these capabilities include: GUI, automation, data base, performance data visualization, correlation (establishing the relationship among pieces of data that originate from different sources), decomposition (breaking down a time measurement, e.g. response time, into its components), and standards.

Performance Data Investigator
Use the Investigate Data task found in the web-based IBM Systems Director Navigator for i to view and analyze the data collected from any of the four data collectors found on IBM i. This powerful tool allows you the ability to work with the data interactively in chart or table form.
PM for Power Systems
A tool that can automatically collect system utilization information and can produce regular reports which show the utilization and growth trends of your system.
Benchmark Center
Services available in Rochester, MN and Montpellier, France to assist you with the measurement and validation of system performance.
Systems Management
Information and solutions for managing all aspects of your system resources to provide you with a competitive advantage.
