WLM: Performance Indexes
This report helps you align goal achievement metrics with overall business performance measurements, such as the cost associated with system performance (for example, adequate response times).
This report analyzes how well Workload Manager (WLM) is doing with achieving its goals. The report shows the distribution of WLM performance indexes across eight performance index ranges. It provides a view of how often WLM goals are met (performance index equal to or less than 1) or missed (performance index greater than 1), and to what degree.
