Kleines Shellscript um von einer AVM Fritzbox Cable mit FritzOS 7.20 die Kabel-Informationen (DOCSIS 3.0) auszulesen und in eine Influxdb zu speichern.
Zur Anzeige der Monitoring-Daten in der InfluxxDB verwende ich Grafana. Hier ist mein Grafana Dashboard inklusive Ping Packet Loss als JSON Export.
