ntop is a network monitoring tool that collects real-time statistics on data traffic. It works by analyzing packets sent through network interfaces, which makes it possible to obtain detailed information about bandwidth, protocols, and the sources and destinations of traffic. Thanks to ntop, administrators can identify traffic patterns, detect anomalies, and optimize network performance. A practical example of using ntop is monitoring the load of individual services within a company, which can help in making decisions about resource allocation. In addition, ntop conforms to industry standards such as ITIL, which makes it a suitable tool in the context of IT service management. It is also worth adding that ntop is available in both open-source and commercial versions, which increases its availability to different types of users.
