Pasos de configuración: Publish a read-only view of Caddy's admin API
Hash a password for the user dumbmonit.
caddy hash-password --plaintext 'a-long-password'Add this site to the Caddyfile, put the hash in place of HASH, then reload Caddy.
:2020 { basic_auth { dumbmonit HASH } @readonly { method GET path /config/apps/http/servers /reverse_proxy/upstreams /metrics } handle @readonly { reverse_proxy localhost:2019 { header_up Host localhost:2019 } } respond 403 }Optional: add metrics to the global options block at the top of the Caddyfile to count requests and errors.
metricsFilter port 2020 so that only the DumbMonit host reaches it.
In DumbMonit, enter the Caddy host with that port, for example caddy.lan:2020, and the user dumbmonit with its password.
Ojo. Never expose the admin API itself: whoever reaches port 2019 can replace the configuration or stop Caddy.
