Tmux plugin to monitor upload and download speed of one or all interfaces.

Add one of the following format string to status-right tmux option.

This plugin is roughly based on the various plugins in https://github.com/tmux-plugins.

Shows value in either MB/s, KB/s, or B/s.

• #{download_speed} - Shows only download speed,
• #{upload_speed} - Shows only upload speed,
• #{net_speed} - Shows both the upload and download speeds. Example: "D: 123 MB/s U: 25 MB/s"
• #{ip} - Shows ip addres from selected interfaces

Since this is a difference, the old values are stored in files in /tmp/. The user must be able to read and write to this directory.

Set the following options in your .tmux.conf.

To change which interfaces to pull from, use a space-separated list. If not set, grabs all the interfaces listed in "/sys/class/net/"

set -g @net_speed_interfaces "eth0 eth1"

Note: ip only takes one interface

To change the formatter sting passed to printf.

set -g @download_speed_format "%10s"
set -g @upload_speed_format "%10s"
set -g @net_speed_format "D:%10s U:%10s"
set -g @net_ip_format "IP(%s): %10s" 

Add plugin to the list of TPM plugins in .tmux.conf:

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

Hit prefix + I to fetch the plugin and source it.

If format strings are added to status-right, they should now be visible.

Clone the repo:

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

Add this line to the bottom of .tmux.conf:

run-shell ~/clone/path/net_speed.tmux

Reload TMUX environment (type this in terminal)

$ tmux source-file ~/.tmux.conf

If format strings are added to status-right, they should now be visible.

This plugin stores the total output for all the interfaces in a file in /tmp/. Therefore, the current user must be able to write and read from that directory.

• Add unit tests
• Add error handling
• Configure which interfaces to calculate
• Configure format string for #{net_speed}
• Handle other OSs (currently only supports Linux)
