A tmux plugin for displaying network upload and download speed in the status bar.

Install using TPM

Add this line to your tmux config file, then hit prefix + I:

set -g @plugin 'wfxr/tmux-net-speed'

Install manually

git clone https://github.com/wfxr/tmux-net-speed ~/.tmux/plugins/tmux-net-speed

Then add the following line to your ~/.tmux.conf:

run-shell ~/.tmux/plugins/tmux-net-speed/net-speed.tmux

Use #{upload_speed} and #{download_speed} in your status-right or status-left options:

set -g status-right '#{upload_speed} #{download_speed}'

This works great with tmux-power:

set -g @tmux_power_show_upload_speed   true
set -g @tmux_power_show_download_speed true

Option	Default	Description
`@net_speed_interfaces`	(empty)	Space-separated list of interfaces to monitor. If empty, all non-virtual interfaces are used.
`@upload_speed_format`	`%7s`	printf format string for upload speed
`@download_speed_format`	`%7s`	printf format string for download speed

Example:

set -g @upload_speed_format   '%s'
set -g @download_speed_format '%s'
