MicroOS server - simple root user notifications?

Hi.

I am testing out MicroOS Tumbleweed as a possible migration route from an Ubuntu based home server with Docker containers. One thing I can’t work out is a simple way (either via email or otherwise) to be notified of any major issues on the server (i.e. a disk SMART failure, or an unplanned reboot). On Ubuntu I have achieved this with Postfix and my GMail SMTP details, but I just can’t achieve the same within the confines of MicroOS. I have even tried installing Prometheus and Grafana but these don’t like the read-only file system.

So, are there any MicroOS users out there with a simple solution to sending alerts to the root user in this way? Any ideas would be much appreciated.

Thanks
Nick

@unholyeyebrows Hi, switch to root user, run transactional-update shell, modify postfix as required, exit the shell (which creates a new snapshot) and then systemctl reboot to the new read-only snapshot.

Thanks for the tips Malcolm. I actually found the error was due to not having cyrus-sasl installed. As soon as I zyppered that in everything worked.

Thanks again
Nick
