Prometheus (9090), Grafana (3000) & cAdvisor (8080) laufen nur lokal auf Hetzner, daher ist es notwendig einen SSH Tunnel zu öffnen, um die Seiten anzuschauen.
Voraussetzung ist natürlich, dass man seinen SSH Key auf dem Server hinterlegt hat.
SSH Connectstring mit mehrfachem Tunnel:
ssh username@144.76.68.113 -p 666 -L 3000:144.76.68.113:3000 -L 8080:144.76.68.113:8080 -L 9090:144.76.68.113:9090
Die Seiten sind dann über http://localhost:9090/, http://localhost:3000/ bzw. http://localhost:8080/ erreichbar.
