How to Display Internet speed in Mbps in system info using conky

SSD · 2022-04-18 09:18:35

I want to display the internet speed in Mbps in system info. Can someone kindly tell what changes do I need to make in conky files and particularly in which conky file to make this happen?

^Conky follows the IEC units convention.

The variables are:

downspeed and downspeedf http://www.ifxgroup.net/conky.htm#upspeed
upspeed and upspeedf

where the output is always B; KiB; MiB etc. You will not get an output in Mbps even if you try to do so using templates (as shown in the screenshot).

So if you have a permanent speed of 1 Mbps, Conky will show you 1 MiB (if my conversion is correct).

The f causes the output of a decimal place and suppresses the letters B; KiB; MiB.
Without f, Conky writes these letters itself and you can omit the 'write to' in the configuration file.

kbit/s oder kB/s

mögliche Schreibweisen:

'bps', 'b/s' = bits per second
'Bps', 'B/s' = bytes per second
'k', 'kb', 'kbs', 'kbps', 'kb/s' = kilobits per second
'K', 'KB', 'KBs', 'KBps', 'KB/s' oder 'k', 'kB', 'kBs', 'kBps', 'kB/s' = kilobytes per second
'm', 'mb', 'mbs', 'mbps', 'mb/s' = megabits per second
'M', 'MB', 'MBs', 'MBps', 'MB/s' oder 'm', 'mB', 'mBs', 'mBps', 'mB/s' = megabytes per second

To your last question you would have to tell which Conky of BL you use.

I'm sure a little lua scripting could convert conky's values into something you want.

An example conky config:

width=330

conky.config = {
    own_window = true,
    own_window_transparent = false,
    own_window_colour = '#FAFCFE',
    own_window_type = 'normal',
    own_window_argb_visual = false,

    double_buffer = true,-- double buffering reduces flicker

-- size of text area
    minimum_width = width, minimum_height = 100,
    maximum_width = width,

   update_interval = 1,

   lua_load = 'test.lua',
   lua_draw_hook_pre = 'main'
};

conky.text = '';

-- This is the test.lua script for use with Conky.
require 'cairo'

function draw_text(text,x,y,font,size,color,alpha,weight,align,maxwidth)
   slant = CAIRO_FONT_SLANT_NORMAL

   cairo_select_font_face (cr,font,slant,weight);
   cairo_set_font_size (cr, size)
   red, green, blue = hex2rgb(color)
   if alpha == nil then
      cairo_set_source_rgb (cr, red, green, blue)
   else
      cairo_set_source_rgba (cr,red, green, blue, alpha)
   end

   local extents = cairo_text_extents_t:create()
   tolua.takeownership(extents)
   cairo_text_extents(cr,text,extents)
   -- cut off text until it fits the maximum width
   if maxwidth then
      did=0
      maxwidth=tonumber(maxwidth)
      while extents.width > maxwidth do
         text=string.gsub(text, "[^\128-\191][\128-\191]*$", "") -- delete last char: stackoverflow.com/a/15980690
         cairo_text_extents(cr,text .. '…',extents)
         did=1
      end
   if did == 1 then text=text .. '…' end
   end

   if align == "right" or align == "center" then
      if align == "right" then
         x = x - extents.width
      else
         x = x/2 - extents.width/2 + extents.x_bearing
      end
   end

   cairo_move_to (cr, x, y+size)
   cairo_show_text (cr, text)
   cairo_stroke (cr)
   return extents.width , extents.height
end

function hex2rgb(c)
   c=tonumber("0x"..c)
    return ((c / 0x10000) % 0x100) / 255, ((c / 0x100) % 0x100) / 255,
            (c % 0x100) / 255
end

function conky_main(...)
   if conky_window == nil then
     return
   end

   cs = cairo_xlib_surface_create (conky_window.display,conky_window.drawable,conky_window.visual,conky_window.width,conky_window.height)
   cr = cairo_create (cs)

   speed = tonumber(conky_parse('${downspeedf enp1s0}'))
   speed = (speed * 1024 * 8) -- in bit
   speed = speed / (1000 * 1000) -- in Mbit? not so sure
   draw_text(speed,10,10,"sans-serif",18,"111111")

   speed = tonumber(conky_parse('${upspeedf enp1s0}'))
   speed = (speed * 1024 * 8) -- in bit
   speed = speed / (1000 * 1000) -- in Mbit? not so sure
   draw_text(speed,10,40,"sans-serif",18,"111111")

   cairo_destroy (cr)
   cairo_surface_destroy (cs)
   cr = nil
   cs = nil
end

Sorry for the vastly complex text_draw function; The important bits are way at the bottom, in conky_main.
I'm not sure exactly how the math goes here, but it is doable.

To your last question you would have to tell which Conky of BL you use.

Can You please elaborate what changes or script do I need to use exactly? I want make changes and add something in "default conckyrc" of Bunsenlabs lithium so that the upload and download speed of the internet is shown in system info tray.

Do I need to paste all(both below and above parts ) script in "default conckyrc" of BL Labs lithium?

In the link unklar gave you, there are examples of what is needed to change. This is a good link with lots of relative information. http://www.ifxgroup.net/conky.htm#upspeed

Typing:

man conky

in a terminal will give you access to everything conky.

You will need to know which conky you want to change, as there are several to choose from for Bunsen Labs. Find the conky you want to change and post the code here of what you want changed and hopefully we can get it fixed up the way you would like.

No, they are separate files. Save the first one to whatever.conkyrc.lua, and the other to test.lua, both in the same folder.
Then you start the conky with

conky -c /path/to/whatever.conkyrc.lua
