1.3.2 Selecting a baseline

Selection of a baseline involves examining performance measurement results and determining baseline values that, together, can be assumed to provide for a level of system operation that is free of problems.

The JP1/PFM products monitor system operations using the baseline values as threshold values. Therefore, selecting a baseline is an important task prior to performing performance monitoring.

We recommend that you obtain baseline measurements at the following times in order to maintain an appropriate baseline:

• When system operation is at peak status, such as when you test heavy loading on the operating environment, obtain measurements of the system's performance.
• Whenever you make changes in the system resources or operating environment, take baseline measurements again because the baseline depends significantly on the system configuration.
