vnStat & vnStati¶
Installation¶
apt install vnstat vnstati
Webseite¶
Um die Statistik auf dem Server anzuzeigen ändern wir in den Dateien /etc/apache2/sites-available/000-default.conf und /etc/apache2/sites-available/default-ssl.conf die Dokumentenwurzel vom Webserver.
DocumentRoot /var/www/vnstat
Nun legen wir noch das Verzeichnis /var/www/vnstat mit mkdir -p /var/www/vnstat an.
Aktualisierung¶
Um die Grafiken für die Statistiken zu aktualisieren lassen wir einen Cronjob alle 5 Minuten ein Script ausführen.
Mit crontab -e legen wir einen Cronjob an und tragen dort folgendes ein.
*/5 * * * * /root/scripts/update-vnstat-graphs.sh
Wir erstellen ein Script unter /root/scripts mit dem Namen update-vnstat-graphs.sh mit folgendem Inhalt.
Achtung
Das Script mit chmod +x update-vnstat-graphs.sh ausführbar machen!
