Customize charts

You can customize more than one monitoring dashboard to place more than one performance metric in one chart. This helps to better locate problems.

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.
