ZFS health monitoring

[Liam Proven]

I have a home server running on a RasPi 4, with Ubuntu Server 20.04,
controlling a USB3 RAIDZ on ZFS.

I have Webmin installed for remote control, and unattended-upgrades
which emails me status reports. I would like to add some kind of
automatic ZFS health monitoring.

I found zfswatcher:
https://github.com/damicon/zfswatcher

...but even its fork:
https://github.com/rouben/zfswatcher

... hasn't been updated in years.

I am trialling this script:
https://calomel.org/zfs_health_check_script.html

I've put an alias in /etc/cron.daily for now. I haven't tried it yet
though -- for now my RAIDZ is healthy.

Is this a good option? Does anyone have a better one?
