Top N & Bottom N Reports

View the highest and lowest values in a defined performance attribute using Top N &Bottom N Reports. The resultant data is displayed in a tabular format in descending order of the monitored parameter. The unified dashboard provides you detailed insights into the report. 
 
How does it help you?
The Top N & Bottom N report pinpoints the performance degradation of your monitored resources. For example, a listing of the Top N websites based on response time allows you to understand how well your websites are performing. The report includes the top 10/25/50/100 websites with the longest response time (the entry appearing at the top) for a preset time period. Whereas the Bottom N report pinpoints the performance degradation of your monitored resources. It lists the bottom 10/25/50/100 websites that had the least response time during a specific time period.
