In my case (120 cores) a configuration with 'CPUs (1&2/4)' on the left side of the header, and 'CPUs (3&4/4)' on the right side of the header looks good. copy ~/.config/htop/htoprc to the larger machine.From the right most column select 'CPU Average' and press F5 to insert it instead.Move down to select 'CPU' and press F9 to delete it.Press F2 to get into the configuration.On a machine where you can see past the header:.

The configuration is saved (under Debian) under ~/.config/htop/htoprc. Using the -F option makes it possible to show packets entering and leaving a given network.Based on grawity's answer, you can create a configuration that you like on a different machine and then copy it to the machine where the problem occurs. Hostname lookup can add substantial traffic in and of itself, and may result in an inaccurate display of network traffic.Ī feature of iftop is that it can suppress display of DNS traffic by using a filter code such as 'not port domain', or switch it off entirely, by using the -n option or by pressing 'n' when the program is running. īy default, iftop will look up hostnames associated with addresses and counts all IP packets that pass through the filter. iftop must be run with sufficient permissions to monitor all network traffic: on most systems this means that it must be run as a root user using the sudo command. If not, it will listen on the first interface it finds that appears to be external (with libpcap and libncurses).

Iftop monitors network traffic and displays a table of current bandwidth usage. It is analogous to top, but instead of system-wide resource monitoring, it focuses on displaying network usage and statistics. By default, the connections are ordered by bandwidth usage, with only the 'top' bandwidth consumers shown. Iftop is a free software command-line system monitor tool that produces a frequently updated list of network connections.
