i try to build a monitoring system for my home server running on a radxa Rock 5C with actual debian bookworm in CLI mode.

i found several guides to build a grafana-prometheus stack in Portainer but stocked by different issues by build the stack.

now i have running grafana, prometheus and node exporter first of two on Portainer, last is running nativ.

but now i cant edit the config file of prometheus. i can find it by /etc/prometheus/prometheus.yml but changes in file are not working (i try to ad my localhost as target for node exporter).

can anybody help me to fix that?
