The biggest advantage of this retrospective network analysis product is that we can either have a long term or short term view on our network running status, and we can choose to look into a specific period of time.

By default, the trend chart shows traffic stats of past 1 second and we can see the traffic utilization, packet count, and traffic volume of each second. If we change the window size to 1-day, each scale on the trend chart represents a day, and the statistics are the sum of each day. The bigger the window size value, the more resources are required on the server to retrieve and analyze the statistic data.
