1.4.2 Selecting a baseline

Before you use a PFM product to monitor system performance, you must select a baseline.

To do this, you select a performance value based on the performance measurement results that is expected to not cause any problems in system operations.

A PFM product uses the baseline value as a threshold when it monitors the system performance. Therefore, selecting the baseline is an important task in performance monitoring.

When you select a baseline, consider the following points:

We recommend that you measure the system's peak state during a situation such as a heavy workload test of the operating environment.

The threshold varies greatly depending on the system configuration. Therefore, after you have modified the system resources or the operating environment, we recommend that you select a new baseline.
