Docker Stats and PVE Exporter are bound to 127.0.0.1 (localhost-only), not 0.0.0.0.
They must be probed from .116 via SSH. Prometheus and Grafana remain 0.0.0.0 (LAN-reachable).

Fixes false alarm from remote probe showing connection-refused (by design for localhost binds).

**Report format**: Summarize actual results from each probe. If any probe returns non-200, flag as alert.
**Note**: All exporters are bound to 0.0.0.0 (not 127.0.0.1) so they are reachable from the LAN.
**Note**: Docker Stats and PVE Exporter are bound to 127.0.0.1 (localhost-only) so they must be probed from .116 via SSH. Prometheus and Grafana are bound to 0.0.0.0 so they can be probed from the LAN.
