Instance View
The instance view is the default drilldown means of monitoring the entire real-time Oracle instance activity. The window offers both a ready and revealing overview and the ability to focus on critical resource usage as reflected in key metric values. Use the instance view to identify trends, bottlenecks, and anomalous resource usage.
The Performance Analysis instance view is a multi-faceted snapshot of Oracle activity. The Activity Timeline Drilldown and Resource Breakdown are the initial visual insights into system performance.
For RAC configurations, this Cluster View displays the composing instances.
