Thanks for sharing! I'll definitely be looking into adding this to my infra alerting stack. Should pair well with webhooks using ntfy for notifications. Currently just have bash scripts push to uptime-kuma for disk usage monitoring as a dead man trigger, but this should be better as a first-line method. Not to mention all the other functionalities it has baked in.
Edit: Would also be great if there was an already compiled binary in each release so I can use bare-metal, but the container on ghcr.io is most-likely what I'll be using anyway. Thanks for not only uploading to docker hub.
