ServeMon asks whether Postgres is actually up

Field notes

ServeMon consolidates services discovered through process data, Homebrew launchd plists, app bundles, and container-engine APIs, including stopped Homebrew services and exited containers. Its checks speak the relevant protocol—such as Redis PING, the Postgres startup message, MongoDB buildInfo, or an AMQP handshake—rather than treating an open port as proof of health. The page also describes local operational data such as PID, uptime, log tail, data directory, and the owning Compose project or repository.
