Hey, this might be something I'm interested in, but I'm not sure because there aren't many details in your readme.

Some questions I'd suggest you answer in the readme:

[Edit: after looking through the code quickly, some of my questions probably don't male sense because this seems to be an alerting style monitoring tool, not a observability style monitoring tool. Answering my own questions for others that are curious:]

What does it monitor?

[Disk space and CPU use]

What is the interface? Web? It does compare itself to grafana, so maybe. TUI? Maybe that's what makes it more light weight?

[It doesn't have one, it sends telegram messages when alarm thresholds(?) are hit.]

Does it only work on Debian? If not, are there deps that are required that are installed as dependencies of the deb?

[Looks like it should work anywhere, the 'watchers' use the nix crate and read procfs, so I assume that means it should work anywhere without depending on anything besides the Linux kernel.]

Is there history or is it real time only?

[Realtime only, well I guess there's the telegram history.]

What does it look like? (Honestly, a screenshot could possibly answer most of these questions and a whole lot more.)

[It doesn't look like anything. There's no screenshot because there's nothing to screenshot.]
