1.3.1 Determining a baseline
Determining a baseline involves using the results of performance measurement to calculate the line at which no system operation problems are anticipated.
Performance Management products treat baseline values as thresholds for system operation monitoring. As such, determining a baseline is important for deciding on a threshold and performing performance monitoring.
Hitachi recommends that you perform the following when you determine a baseline:
-
Measuring statuses during peak times, such as by performing testing under heavy operation environment load
-
Re-measure baselines when system resources or operation environments are changed, as these can differ significantly by system configuration
