The heat chart displays the state of resources in your perspective—whether the resources are running, suspended, or down. In addition, the heat chart lists the type of each resource and provides statistical data, including the start time of the last data collection.
You can filter the resources that you want to see and search and sort the results by column. You can also select a resource and pull down its context menu to see monitoring and administrative options that vary based on the resource type.
Heat chart data is collected directly from managed servers, tagged with the date and time when it was collected, and stored in the SAP Control Center repository.
