I've got the same problem, I have an ubuntu fileserver I set up a few years ago, but have none of the monitoring/alerting that I'd have if I set it up for my day job. And really, I don't want to do my day job at home.

So it's a bit of a catch-22, I want a secure and stable home system, I don't want to spend much time working on it, but I want full flexibility to install and run what I want, and don't want to trust some off the shelf consumer solution that's likely going to be out of support in a couple years.
