I have a small bandwidth mobile phone contract so I need to control my usage of bandwith.
I use vnstat (https://humdi.net/vnstat/)
It is not sophisticated but it works.
Example of result:
rx / tx / total / estimated

I haven't found no ubuntu repo with vnstat compiled for our platform so I get it from debian.
Here I get the version of debian depending on my version of ubuntu:
So I'll download for version 15:
And for version 16 (Sorry Haven't tried it, still on 15!!!) should be
Next I need to check my arquitecture so I open a console on my phone and
In my case the answer is
armf ( vegeta)
So I download the correct version
http://ftp.de.debian.org/debian/pool/main/v/vnstat/vnstat_1.12-2_armhf.deb for ubuntu 15.
In order to dpkg a file the filesystem needs to be on read write mode.
mount /dev/loop0 / -o remount,rw
sudo dpkg <filename>
My root filesystem is on readOnly mode most of the time. Vnstat needs to keep info and It can't be on base filesystem.
I Edit the /etc/vnstat.conf and put the database dir inside the home.
and reboot the phone (I don't know if this is mandatory ).
create dir /home/phablet/.vnstat
First I need to tell vnstat to control the ccmni0 connection.
vnstat —create -i ccmni0
finally I have a script with this instructions:
sudo vnstat -u
sudo vnstat -i ccmni0 -d -s
The first one updates vnstat internal counters and the next one gives the already shown result.
