Vnstat how-to

Steve_B

PM me if you need any advice on the UI conversion. The pinned notes on this page should help.

So apparently the only package not yet on their list that likely will be converted to 2.3 is NUT. Not looking good for vnstat unless someone steps up to do the conversion.

If I had the time and knowledge, I'd probably take a stab at it… but I don't have either. Happy to help test and give feedback... just not one for coding.

If someone knows of a developer who has the ability to do this, I would be happy to spearhead a crowdsource campaign to commission the conversion.

I managed to install vnstat 1.14 from the FreeBSD repo. Then downloaded the vnstat php interface from http://www.sqweek.com/sqweek/index.php?p=1 and added it manually to /usr/local/www/vnstat

Now the only thing that doesn't work is the graphic on the php interface. Seems like it is missing php-gd to generate the graphics, I think.

Here's the error from the img call of the graph.php page:

Fatal error: Call to undefined function imagecreatetruecolor() in /usr/local/www/vnstat/graph.php on line 61 Call Stack: 0.0002 120032 1\. {main}() /usr/local/www/vnstat/graph.php:0 0.0165 181428 2\. output_image() /usr/local/www/vnstat/graph.php:302 0.0165 181540 3\. init_image() /usr/local/www/vnstat/graph.php:282

At least I have my numbers! Just not as pretty as I wished it was :)

Is there not a package in the FreeBSD repository to install php-gd? Or is it a different version of PHP than what pfSense has/uses?

When I manually installed it - it wanted a couple of libraries, font package - 4 or 5 dependencies if I remember correctly

I think that also might explain the reason the developers got away from the RRD graphs and are using the new monitoring graph instead… because of all the dependencies associated with php-gd that they would need to maintain in the pfSense package repository. Which is also probably why vnstat isn't on their list to port.

Doing a little digging... maybe this could work instead? It's javascript-based, served from php, with no mention of php-gd being needed... https://rakudave.ch/about_jsvnstat/

are you sure its missing php-gd? I think its because your missing libgd-2.1.0_7,1.txz. I got it working right away with a manually install but I used the frontend interface from the previous package. You can get all the files minus the vnstat binary here: https://github.com/pfsense/pfsense-packages/tree/master/config/vnstat2

To install vnstat binary, I needed the following packages install:

http://pkg.freebsd.org/freebsd:10:x86:64/release_3/All/png-1.6.20.txz
http://pkg.freebsd.org/freebsd:10:x86:64/release_3/All/jbigkit-2.1_1.txz

http://pkg.freebsd.org/freebsd:10:x86:64/release_3/All/freetype2-2.6.2.txz
http://pkg.freebsd.org/freebsd:10:x86:64/release_3/All/fontconfig-2.11.1_1,1.txz

This seems like a very promising interface, I will definately give it a try!

Interesting as well, I will check it out later on!

I don't remember the exact dependancies, but yes that was a big reason. The new version of rrdtool (with graphing libraries) was going to double the size of the whole image.

Nice find, I'll have to take a look. With "a little work" I could probably do the same thing we did with RRD to the vnstat package (with a similar interface to that package) and get back bandwidth totals. If we could cut out the front-end dependencies that would be great (I wonder what their size/percentage of the total is). I have a lot to work on though so unfortunately this is low man on the totem pole for me right now.

I would also greatly appreciate getting this function to work again in 2.3.

Here are the directions I used to manually install vnstat:

ssh into router, cd to /root, download these:
fetch http://pkg.freebsd.org/freebsd:10:x86:64/latest/All/vnstat-1.14.txz
fetch http://www.sqweek.com/sqweek/files/vnstat_php_frontend-1.5.1.tar.gz

this will ask to install dependencies, say yes

pkg install vnstat-1.14.txz

this copies your existing vnstat data to a new home and leaves the existing files untouched

mkdir -p /var/lib
cp -rp /cf/conf/vnstat /var/lib
chown -R vnstat:vnstat /var/lib/vnstat

install the frontend

cd /usr/local/www
tar xvf /root/vnstat_php_frontend-1.5.1.tar.gz
mv vnstat_php_frontend-1.5.1 vnstat

configure front end, I use vi, use ed or whatever you prefer

vi vnstat/config.php
change $language to en: $language = 'en';
change $iface list to your interfaces, e.g.:
$iface_list = array('em0', 'em1', 'em2');
add/edit the title lines for your interfaces, e.g.:
$iface_title['em0'] = 'LAN';
$iface_title['em1'] = 'WAN';
$iface_title['em2'] = 'JUMBOLAN';
change $vnstat_bin = '/usr/local/bin/vnstat';

fix image output:

vi vnstat/graph_svg.php
edit line 156:
svg_text($iw / 2, ($ytm / 2), $text, array( 'stroke' => $cl['text'], 'fill' => $cl['text']['rgb'],'
stroke-width' => 0, 'font-family' => SVG_FONT, 'font-weight' => 'bold', 'text-anchor' => 'middle' ));
to:
svg_text($iw / 2, ($ytm / 2), $text, array( 'stroke' => 'none', 'fill' => $cl['text']['rgb'],'
stroke-width' => 0, 'font-family' => SVG_FONT, 'font-weight' => 'bold', 'text-anchor' => 'middle' ));

run this once to make sure there are no errors

/usr/local/bin/vnstat -u

add the crontab entry to update the stats

crontab -e
*/5 * * * * /usr/local/bin/vnstat -u

And that should be it. Go to http://yourrouter/vnstat/ to view the results.

vnstat is available for manual 'pkg install' now. That's a first step towards getting the full package back.

Just SSH in, and run:

pkg update 
pkg install vnstat

To install it.

Followed instructions, rebooted PFsense, see no package installed and no VNstat under status, any more instructions available/needed?

jdillard

That just installs the FreeBSD package. It won't show up in the GUI, it's all CLI: http://humdi.net/vnstat/man/vnstat.html

Profound sadness, thanks for the update though!

I am working on a front-end for it. You can scroll through my post history if you want more info/screencasts.

My vnstatd is working perfectly on my 2.3.1 box. I have also added a rc.d script for startup/shutdown to try to prevent corrupt data files.

Location: /usr/local/etc/rc.d/vnstatd.sh


#!/bin/sh

. /etc/rc.subr

name="vnstatd"
rcvar=vnstatd_enable

load_rc_config $name

: ${vnstatd_conf="/usr/local/etc/vnstat.conf"}
: ${vnstatd_flags="-d --config ${vnstatd_conf}"}

required_files=${vnstatd_conf}
command="/usr/local/sbin/vnstatd"

run_rc_command "$1"

Added this to my /etc/rc.conf.local

vnstatd_enable="YES"

Now vnstatd starts at boot time and stops at shutdown.

I also added a backup script (that definately need tuning in order to only keep maybe a few days of backup in case something goes unnoticed). It was added to the crontab to run every hour

0 * * * * /root/vnstat_backup.sh >/dev/null 2>&1

Here is the /root/vnstat_backup.sh. I'm not sure if I had to install bash, but I think I did :

#!/usr/local/bin/bash

#START
TIME=`date +%Y-%m-%d_%H%M`		# This Command will add date in Backup File Name.
FILENAME=$TIME.tar.gz			# Here i define Backup file name format.
SRCDIR=/var/db/vnstat			# Location of Important Data Directory (Source of backup).
DESDIR=/root/vnstat_backup		# Destination of backup file.
#echo $TIME
tar -cpzf $DESDIR/$FILENAME $SRCDIR
#END

This script creates a ton of files that need to be cleaned manually once in a while, so if someone could tune it to delete files older than X days it would be great! :)

Just curious if there's any update, Comcast is rolling out more data caps and Fios is still working on outfitting our building.

johnpoz

I just got an email from comcast about caps - its 1TB.. are you actually using more than 1TB a month?
