Establishing a baseline in a monitoring network segment is an important measure in network monitoring, and there is no baseline flow without a comparison criterion, which can be used to detect the traffic changes that cause the problem. By sniffing packets, conducting protocol analysis (implemented through NTOP), and providing Sflow/netflow monitoring sample data under the Ossim platform, the data is most often stored in the system for up to 1 years. I'll show you a few examples below.

In fact, this is a common way of bandwidth billing, at a certain time interval (for example, 5 minutes), the bandwidth consumption to take value, and then remove the highest 5%, the remaining 95% of the bandwidth is your network traffic. This unit also often appears in cacti if you pay attention to the observation.

Well, about Ossim query historical traffic content is simply introduced here, there are a lot of practical functions hidden in the system, the key is how you use her good.
