COMMAND: The name of the command that started the process.TIME+: How much processor time the process has used.MEM: The percentage of physical RAM used by the process.CPU: The percentage of the processor time used by the process.S: The current status of the process (zombied, sleeping, running, uninterruptedly sleeping, or traced).SHR: How much shared memory the process is using.Click on the release notes icon for the latest release for more info. Color Codes HTTP, TCP,UDP, ICMP, VPN, P2P, etc. RES: How much physical RAM the process is using, measured in kilobytes. bandwidthd Tracks usage of TCP/IP network subnets and builds html files with graphs to display utilization.VIRT: How much virtual memory the process is using.NI: The nice value of the process, which affects its priority.The lower the number, the higher the priority. PID: A process ID number for the process.The following are definitions for each column in the output: The command used to start the process is also included. IPTraf-ng is an ncurses-based IP LAN monitor that generates various network statistics including TCP info, UDP counts, ICMP and OSPF information, Ethernet load info, node stats, IP checksum errors, and others.The htop tool lists all running processes on the system and includes information about how much CPU and memory each process is using. iftop -i interface # (specify interface.Dstat overcomes some of the limitations of these programs and adds some extra features.ĭstat allows you to view all of your network resources instantly, you can for example, compare disk usage in combination with interrupts from your IDE controller, or compare the network bandwidth numbers directly with the disk throughput (in the same interval).ĭisplays bandwidth usage information on an network interface iftop does for network usage what top(1) does for CPU usage. The Color Bandwidth Meter (CBM) is a small program to display the traffic currently flowing through the network devices in a simple curses-based GUI.ĭstat is a versatile replacement for vmstat, iostat and ifstat. Small and simple console-based bandwidth monitor In alphabetical order, with an excerpt of the description: apt show bwm-ng cbm dstat iftop iptraf-ng nethogs nload Nethogs as suggested in the accepted answer is probably the right tool to see network usage by process.įor other console network monitoring tools, here is a list of current tools on Debian 11 (or Ubuntu 20.04 LTS).
