[SOLVED] Hurray! I did it!

Solution: You need to have Generic monitor xfce link installed [available almost on every DE out there]

Two finger Tap on Panel Panel (dropdown) > Panel Preferences > Items > Add Item > Generic Monitor

In generic monitor give the exact location of the script like I have done here (also copy other details too)

Now save

Here's what is in the trial file

#!/bin/bash
eleven=$(vnstat --json | jq --arg day "$(date +'%d')" --arg month "$(date +'%m')" '.interfaces[0].traffic.day[] | select(.date.day == ($day | tonumber) and .date.month == ($month | tonumber)) | (.rx + .tx) / (1024*1024*1024)')
rounded_eleven=$(printf "%.2f" "$eleven")

echo " $rounded_eleven GB"

And that' about it, for Network Usage Gouger you need Network Monitor Package xfce4-netload-plugin You can see more into here

Adios!

[ORIGINAL POST]

edit: I am open to installing other packages, I ain't married to any of these packages.

I have installed vnstat package and it's quite handy. I have a few questions about it though.

1. What is rx & tx mean in this package? rx stands for received tx stands for transmission

Is there a command to check data usage on my system using this? I mean, I want to create a Add an item to my panel which will show me my daily data usage updating it every minute. Basically, I want to to see what the arrow points to on the panel next to my date and I want it to update it every minute. I have 1.5GBs of data a day and I usually am not able to use it efficiently or I use too early and spent hours without data. So, I want to try and handle this problem by monitoring my data.

Note: I want to measure gauge data speed here, not do a speed test on how fast my internet is.

Also, I want to monitor the instantaneous rate of data usage and for that package bwm-ng does a great job, but I want to see in the panel and I want it to update every 0.5 s how can I achieve this?

I would like for a command to either view red arrow or the black arrow with the right mark depending upon which of them is instantaneous data speed

Note to Future self: rx : received tx : transmission lo : local loopback wlan0 : ethernet
