Moderate to move
CloudWatch on Hetzner (US): what it becomes and what it costs.
On Hetzner (US), CloudWatch becomes Prometheus + Grafana + Loki on Hetzner Cloud servers (US). Metrics, logs and alerts are well covered by open source; dashboards need rebuilding.
Effort grade
Moderate
Same software, self-hosted: you patch, back up and fix it
Cost after the move, before engineer time
30% of today
Logs ingest at $0.50/GB, custom metrics at $0.30 each and alarms dominate most bills; Prometheus, Loki and Grafana on a CX43 (€16) plus object storage for logs come to about 30%.
Engineer time
6 h a month
To run the replacement: patching, backups, on-call. Plus about 5 engineer days for the move itself.
