Ntop function Summary

Ntop function Summary-Linux Enterprise Application-Linux server application information. The following is a detailed description. Ntop can display IP address-based bandwidth usage, help network administrators quickly locate users and applications that maliciously seize network bandwidth, and collect statistics based on protocol types and generate intuitive charts, helps network administrators understand the composition and proportion of business traffic, and then optimize the network based on this.

Total data traffic of network servers (total data transfer of network cards), and packet transfer rate (or traffic) of CPU usage and special services ), network administrators must pay attention to this issue. When traffic changes abnormally, hackers may try to steal our information. In terms of network management, it is necessary to know the network traffic status of our Linux server and limit or increase the bandwidth based on the traffic. The NTOP mentioned in this article is open source software, but I think it is really inferior to other commercial management software.

Conclusion: As an ordinary network user, when the Internet is vast, no one will notice that the dark flow is surging under the calm sea. Generally, network managers need to know the usage of each network segment, the bandwidth usage, and the bottleneck of network problems. When a network problem occurs, you must be able to quickly locate the cause of the problem in the area and quickly locate the line problem, network device problem, or the routing and fire wall setting problem. In a slightly smaller network, it is not difficult for an experienced manager to answer these questions. However, if the network scope is too large, an efficient network management system is required. In a busy business network, the network suddenly slows down. During the period of time when important data is exchanged, the response time left for the system administrator is only 10 minutes or even several minutes. If you cannot answer why the network is slow? The answer must be obtained through scientific and reasonable calculation and statistics and in a pre-established traffic analysis system.
