[Solved] vnstat (Data Limit Exceeded Notification)

[bester69]

Hi,
Im going to use data mobile internet with my laptop, and would like to get/set a daily maximum data exceded message..
Is there anything for vnstat to get a quote rate data limiter/notifier?


Any suggestion?



Thanks.

I made a script to update every hour vnstat and verify that the maximum data quota is not exceeded.



/etc/crontab.hourly/cr_data_limiter

cr_data_limiter

Code: Select all

#!/bin/sh
#
PATH=/sbin:/bin:/usr/sbin:/usr/bin
export PATH
DISPLAY=:0 ; export DISPLAY
su user -c "/home/user/scripts/data_limit.sh" 
exit 0

data_cleanvnstat.sh (Reset daily data counter)

Code: Select all

#!/bin/bash
#
sudo /etc/init.d/vnstat stop
sudo rm /var/lib/vnstat/wlan0    
sudo /etc/init.d/vnstat start
sudo vnstat -i wlan0 -u

data_limit.sh

Code: Select all

#!/bin/bash
#
clear
#Max == Maximum Megas daily
Max=5 
ring="/home/user/Música/ringstones/Alarms/Nobelium.ogg"

sudo vnstat -u
Vstat="$(vnstat -i wlan0 | grep today)"
Vd=$(vnstat -i wlan0 | grep today | awk '{print $8}') && Vd=${Vd%,*}
Vf=$(vnstat -i wlan0 | grep today | awk '{print $9}')

vnstat -i wlan0 | grep today
echo "Vd=$Vd"
echo "Vf=$Vf"
 
case "$Vf" in 
  MiB) 
  echo "MiB"
if [ "$Vd" -gt "$Max" ]
    then
    echo "$Vd > $Max"
    notify-send "Daily Limit Exceeded!" "Total Data Usage $Vd $Vf\n $Vstat" -i kate -t 600000
    killall ffplay
    ffplay -autoexit -loop 1 -nodisp -nostats -loglevel 0  "$ring" &
   sudo /home/user/scripts/data_cleanvnstat.sh
