Compare performance trends
You can compare the trends of a performance metric between any two time periods.

If this is the first time that you use this function, follow these steps to create a monitoring dashboard:
- On the Custom Chart tab, click Add Monitoring Dashboard. In the displayed dialog box, enter the dashboard name and click OK.
- Click Add Monitoring Chart, enter the chart name, select performance metrics (after you do so, the Charts section displays the selected performance metrics in line charts), and then click OK.
After the creation is complete, you can view the monitoring dashboard, switch to another monitoring dashboard, and manage the monitoring dashboards through the menu provided in the upper-left corner.
