From a performance report card, you can click on a device or site name to view additional details.
The drilldown page will change depending upon which periods and aggregate options you have selected in the report setup.
If you chose to aggregate the data by both the percentage uptime and the average response time, the percent uptime will display on the left as both a green bar chart as well as a numerical percent. The average response time will display in the right hand column as a decimal.
Each period selected will display as a distinct row on the drilldown report.
