i3status

Example .i3status.conf

general {
	output_format = "i3bar"
	colors = true
	interval = 5
}

order += "disk /"
order += "ethernet eth0"
order += "load"
order += "time"

ethernet eth0 {
	# if you use %speed, i3status requires the cap_net_admin capability
	format_up = "E: %ip (%speed)"
	format_down = "E: down"
}
time {
	format = "%Y-%m-%d %H:%M"
}
load {
	format = "%5min"
}

Custom i3status command, the python way

Code from here

#!/usr/bin/env python
# -*- coding: utf-8 -*-

# This script is a simple wrapper which prefixes each i3status line with custom
# information. It is a python reimplementation of:
# http://code.stapelberg.de/git/i3status/tree/contrib/wrapper.pl
#
# To use it, ensure your ~/.i3status.conf contains this line:
#     output_format = "i3bar"
# in the 'general' section.
# Then, in your ~/.i3/config, use:
#     status_command i3status | ~/i3status/contrib/wrapper.py
# In the 'bar' section.
#
# In its current version it will display the cpu frequency governor, but you
# are free to change it to display whatever you like, see the comment in the
# source code below.
