Installation for Koozali SME v10

You need the EPEL repo 

yum install smeserver-extrarepositories-epel

Now install vnstat: 

yum --enablerepo=epel install vnstat

Next a configuration entry and unit file 

config set vnstat service status enabled access private
mkdir -p /usr/lib/systemd/system/vnstat.service.d
nano /usr/lib/systemd/system/vnstat.service.d/50koozali.conf

Paste this and save/exit: 

[Unit]
Description=Vnstat global service for Koozali SME Server

[Install]
WantedBy=
WantedBy=sme-server.target

Add service key: 

config set vnstat service status enabled access private

And Upgrade/Reboot for good measure: 

signal-event post-upgrade
signal-event reboot

Are we running: 

systemctl status vnstat

Lets look at the data: 

                     rx      /      tx      /     total    /   estimated
eth0:
      Mar '24      4.36 MiB  /   22.12 MiB  /   26.48 MiB  /   40.00 MiB
        today      4.36 MiB  /   22.12 MiB  /   26.48 MiB  /      37 MiB

vnstat --iflist
vnstat -i eth0

By hour/week/month 

vnstat -h/w/m -i eth0

eg 

vnstat -w -i eth0

Remove unwanted DBs and stop monitoring the interface 

vnstat -i dummy0 --delete --force

This could be templated: 

cat /etc/vnstat.conf


Installation for Koozali SME v9

To install vnStat you will need to have the Dag repository configured on your system. If you do not have the repository installed follow this instruction, otherwise skip to the next section:

Configuring Dag repository

You need to activate the Dag reposity before installing this contrib.

see dag repository

Install vnStat

If you have configured the dag repository, installation is as simple as: 

yum install vnstat --enablerepo=dag
signal-event post-upgrade
signal-event reboot

Add the monitored Interfaces

Add the interfaces you would like to monitor: 

vnstat -u -i eth0
vnstat -u -i eth1

You should get an error about the database not existing but it will also say it created it. It is safe to ignore the error message.

you also need to edit /etc/sysconfig/vnstat to add your iface to the update job 

vim /etc/sysconfig/vnstat

VNSTAT_OPTIONS="-u"

see http://forums.contribs.org/index.php/topic,45174.0.html

Install vnStat PHP FrontEnd

"...Since vnStat is console mode only I created this script to make a 'nice' report of the data collected by vnStat...." (Read More)

There is no yum repo for this so you will need to go to: http://www.sqweek.com/sqweek/index.php?p=1 to find the latest. Determine the link to the latest release and replace the wget command (below) accordingly.

The below instructions put the file into the Primary ibay, you can also put it in a dedicated ibay or in /opt as suits your needs and security requirements.

Get the frontend and configure: 

cd /home/e-smith/files/ibays/Primary/html/
wget http://www.sqweek.com/sqweek/files/vnstat_php_frontend-1.4.1.tar.gz
tar -xvzf vnstat_php_frontend-1.4.1.tar.gz
cd vnstat_php_frontend-1.4.1

nano config.php:
Edit the information about the interfaces you would like to graph: 

$iface_list = array('eth0', 'eth1');

The optional names: 

$iface_title['eth0'] = 'Internal';
$iface_title['eth1'] = 'Internet';

Finnaly set application path: 

$vnstat_bin = 'vnstat';

Wait and you should see the application working at http://yourserverIP/vnstat_php_frontend-1.4.1

Troubleshooting

It is advisable to make the following change (as per user advice here http://forums.contribs.org/index.php/topic,45174.msg218884.html#msg218884)

Edit the vnstat cron file 

nano /etc/cron.d/vnstat

Change the line 

*/5 * * * * nobody /usr/sbin/vnstat.cron

to read 

*/5 * * * * root /usr/sbin/vnstat.cron

Restart crond. 

service crond restart
