MySQL replication status monitoring

Anurag Bhatia
Background I am running my own authoritative DNS servers for the last few years. In earlier stages I just used registrar-provided DNS, later moved to “Cloud provider” provided DNS and ultimately settled for running my own auth DNS. Two major requirements pushed me to self-host auth DNS: Requirement of REST API for DNS needed by the web servers to resolve Letsencrypt certbot DNS-based challenge. This allows me to have internally hosted tools with Letsencrypt issues TLS certificates instead of self-signed ones.
