Nethogs IntroductionNethogs is an open-source, free, terminal network traffic monitoring tool that monitors the network traffic of Linux processes or applications. Nethogs can only monitor the network bandwidth consumption of the process in real time. Nethogs supports IPV4 and IPV6 protocols, supports local network cards, and PPP links.The official introduction is as follows:Nethogs is a small ' net top ' tool. Instead of breaking the traffic down per

which the RAM segment can be moved to a special disk segment of swap disk, where the page export and page import of virtual memory occur, and page export does not indicate a ram bottleneck. The virtual memory system often makes page exports to the memory segment, but the page import operation indicates that the server needs more memory, and the page import needs to copy the memory segment from swap disk back to RAM, causing the server to become slower.There are several ways to solve this proble
