One Go binary, one YAML file, one SQLite database: I wrote my monitoring tool

Single Go binary + SQLite database all the way.

I've been doing this architecture on single tenant VMs for like 6+ years now and it has so many advantages for deployments, security and scaling.

Pretty much every new tool and agent computer I set up uses this pattern. I've blogged about it and created a template repo.

I like it but use Rust instead

Nice! But you made a mistake of using smallcaps-only on the repository. MacOSX file systems will complain and all sorts of weirdness can happen.

Recently I vibe coded a couple of scripts invoked by cron to do the same thing for a few services running on a single node for me. Works beautifully.
