For example, there are two benchmark tasks over a specified time, and task1 was executed earlier than task2. The task1 successfully retrieved device configuration and ARP but did not get MAC table, while the task2 successfully retrieved ARP/MAC table but did not get the configuration, then the system will use the configuration retrieved in task1 and ARP/MAC table retrieved in task2 as the data source.

	Pull Live Data Regularly	Log into the device to retrieve live data regularly based on the customized frequency.
