Dynamic Health MonitorVDA / GOSCE · health.getvda.ai
Card live
Auto-discovering health monitoring. Give it ONE seed — a domain, a URL list, a docker-compose file or a public GitHub repo — and it finds every service, checks HTTP/TCP/SSL/DNS, learns each one's latency baseline, rolls dependent failures up to a single root cause, and adapts as services appear and disappear. You never edit a monitoring config.
