Description

Monitors network interfaces and shows current traffic.

local mynet = lain.widget.net()

Input table

Variable	Meaning	Type	Default
timeout	Refresh timeout seconds	number	2
iface	Network device(s)	string (single interface) or array of strings (multiple interfaces)	autodetected
units	Units	number	1024 (kilobytes)
notify	Display "no carrier" notifications	string	"on"
screen	Notifications screen	number	1
settings	User settings	function	empty function

iface can be a string or an array of the form { "eth0", "eth1", ... } containing a list of the devices to collect data on.

If more than one device is included, net_now.sent and net_now.received will contain cumulative values over all given devices. Use net_now.devices["eth0"] to access sent, received, state or carrier per device.

Possible alternative values for units are 1 (byte) or multiple of 1024: 1024^2 (mb), 1024^3 (gb), and so on.

If notify = "off" is set, the widget won't display a notification when there's no carrier.

settings can use the following iface related strings:

• net_now.carrier ("0", "1");
• net_now.state ("up", "down");
• net_now.sent and net_now.received (numbers) will be the sum across all specified interfaces;
• net_now.devices["interface"] contains the same attributes as the old api for each interface. More on this in the "Multiple devices" section below.

For compatibility reasons, if multiple devices are given, net_now.carrier and net_now.state correspond to the last interface in the iface array and should not be relied upon (deprecated).

Output table

Variable	Meaning	Type
widget	The widget	wibox.widget.textbox
update	Update widget	function

Notes

Setting iface manually

If the widget spawns a "no carrier" notification and you are sure to have an active network device, then autodetection is probably not working. This may due to your user privileges. In this case you can set iface manually. You can see which device is UP,LOWER_UP with the following command:

ip link show

Two widgets for upload/download rates from the same iface

local mynetdown = wibox.widget.textbox()
local mynetup = lain.widgets.net {
    settings = function()
        widget:set_markup(net_now.sent)
        netdowninfo:set_markup(net_now.received)
    end
}
