thing that the CPU usage of a vro occasionally reaches the highest point of 100%. This indicates that the device has no spare time. However, if a CPU usage rate is 100% for a period of time, it may indicate packet loss. In this case, you should check other information, such as packet discard.The opposite example is the half-duplex, 10 BaseT Ethernet utilization of shared media. Even if the maximum theoretical capacity of 10 BaseT is 10 MB, in some ca

What is Nethogs? Nethogs is an open source command-line tool (similar to the Linux top command) for real-time statistics of network bandwidth usage by process or program. From Nethogs Project website: Nethogs is a small ' net top ' tool that does not slow down each protocol or the speed of each subnet, as most tools do, but to group bandwidth by process. Nethogs Nethogs does not need to rely on loading a particular kernel module. If there is a

There are many open-source network monitoring tools available on the web for Linux operating systems. For example, you can use the command iftop to check bandwidth usage. Netstat is used to view the interface statistics report and the current running process of top monitoring system. But if you want to find a way to count network bandwidth utilization in real tim

Use iftop to monitor network traffic and iftop to monitor network traffic Iftop is a useful tool. The following command monitors the wireless network card of my notebook iftop -i wlan0 For example, if I play a video of letv, The iftop displays the following information:
