Introduction › Performance Manager Features › Analysis and Reporting Facility

Analysis and Reporting Facility

The analysis and reporting facility generates the Analysis Report, the Brief Analysis Report, the Performance Evaluation Report, the Tabular Report and histograms. The Analysis Report identifies the effects of system parameter settings, hardware configurations, workload mixes, and applications when they degrade the performance of individual nodes in the cluster or the entire cluster system. Conclusions and recommendations are based on data collected.

The Brief Analysis Report is a synopsis of the Analysis Report. It contains a one-line description of each rule fired. For more detail, produce a full Analysis Report.

You can also request a Performance Evaluation Report or Tabular Report to help you determine improved or degraded system performance. You can also request histograms that consist of chronological charts that show peak resource use. You can select a specific set of items (disks or processes) for reporting.

The ADVISE PERFORMANCE REPORT command invokes analysis of performance data to generate Performance Manager reports.

You can specify five types of reports:

• Analysis Report-Consists of conclusions for each node and includes cluster-wide conclusions for a clustered system. You can request the conditions that caused a rule to fire and the supporting evidence.
• Brief Analysis Report-Is a brief version of the analysis report. It includes a one-line synopsis of each rule firing.
• Histograms-Consists of chronological charts that show peak resource use.
• Performance Evaluation Report-Consists of metrics for measuring performance improvement or degradation. Use these metrics to evaluate the recommendations made by Performance Manager and to measure results against baseline models.
• Tabular Report-Provides a consolidated summary of some of the performance metrics related to system-wide activity, process activity and disk activity.
