Sto cercando di mettere su un monitoraggio dei container (e sei due qnap) che ho a casa. Ho installato Prometheus, Grafana, node-exporter e per la parte container stavo provando ad installare cadvisor, ma per quanto posso vedere in giro sulla configurazione che pià che altro sono mapping di cartelle, va in errore.
Gli errori espliciti nei log che vedo sono questi:

Qualcuno ha provato ad installarlo per docekr su qnap? Alternative eventualmente?
Grazie
