The Performance menu provides information about the hosts associated with your environments.
When you first access the Performance dashboard, a message will be displayed asking you to select an environment to report metrics for. To do this, follow the steps in the My Environments section in Working with Oracle Pulse.
By default, host and database metric reports on the Performance dashboard are generated in the GMT time zone. However, you can identify potential issues in your own time zone by changing the time zone in which the reports are generated, as explained in the Changing the Timezone of Your Reports section in Working with Oracle Pulse. This allows you to easily relate performance metrics reflected by individual host and database charts and metric comparison charts to anomalies occurring across the selected environment.
