History
The History option, selectable from the navigator, allows the administrator to examine the historical performance of the ADC. Historical views can be generated for Virtual Services, Real Servers, and System.
It also allows you to see load balancing in action and helps catch any errors or patterns that need investigating. Note that you must enable historical logging in System > History to make use of this feature.
