You can create workload snapshots to record cluster workload data in a specified period. A workload diagnosis report can be generated based on two workload information snapshots within a certain time segment. Workload Diagnosis Report (WDR) provides performance data in a specified period and presents the data on HTML web pages. It helps you detect exceptions, diagnose problems, and optimize performance. It is a powerful tool for database performance tuning.</p>
