Dashboards v8
PEM displays performance statistics through a number of dashboards. Each dashboard contains a series of summary views that contain charts, graphs, and tables that display the statistics related to the selected object.
Dashboards overview
The PEM client displays the Global Overview dashboard when it connects to the PEM server. Additional dashboards provide statistical information about monitored objects.
Opening dashboards
You can open a dashboard using either of these techniques:
- Select an active dashboard name from the Management > Dashboards menu.

Use the Configure section to specify general information about the dashboard:
- Specify a name for the dashboard in the Name field.
- Use the Level list to specify the level of the PEM hierarchy in the PEM client on which to display the dashboard. You can access a dashboard using the Dashboards menu on a global level, an agent level, the server level, or the database level. Each selected level in the list exposes a different set of metrics on which to base the custom dashboard's charts.
- Provide a description of the dashboard in the Description field.
Provide information in the Ops dashboard options box to use the dashboard as an Ops dashboard:
- Set Ops Dashboard? to Yes to create a dashboard that's formatted to display on an Ops monitor.
- Set Show Title? to Yes to display the dashboard name at the top of the Ops dashboard.

After you complete the Configure Dashboard section, select the arrow in the upper-right corner to close the section and access the Dashboard Layout Design section.
Select Edit in a section header to specify a section name. Then, select the plus sign (+) to add a chart to the section.
Use the arrows to the right of each chart category to display the charts available and select a chart.
