===Configure necessary repositories===
===Installation for Koozali SME v10 ===
===Install vnstat===
You need the EPEL repo
====Using Yum====
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 ===
