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"
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.
