Use Ntop to monitor network traffic ____ Network traffic reflects the running status of the network, which is the key data for determining whether the network is running normally. In the actual network, if the network traffic is not well controlled or the network is congested, this will cause a decrease in network throughput and network performance. Traffic measurement not only reflects the normal operation of network devices (such as routers and swit
