Puertos de red que abrir
3100/TCPLoki HTTP API (default)
Pasos de configuración: Let DumbMonit read Loki's own health
Nothing to install: check from the DumbMonit host that Loki answers on its HTTP port (3100 by default).
curl http://loki.lan:3100/readyLoki has no login of its own: only if a reverse proxy in front asks for one, pick Username / password (or Bearer token) below.
In DumbMonit, enter Loki's address, for example "loki.lan" or "https://logs.lan/loki" behind a reverse proxy.
With Loki split into components (simple scalable or microservices), add at least the write path.
Ojo. Refused lines are the failure to watch: when Loki refuses a line (too old, over a rate or stream limit, too long), the sender usually drops the batch and Grafana only shows a gap in the logs.
