If you’re willing to go that route, check out Zabbix and Icinga2 as well. They’re compatible with Nagios checks but the user interface is better.

I use ssmtp as well for a simple sendmail replacement. It takes over the sendmail command, doesn’t open any ports. You configure it for the domain you want and tell it what server to send everything to and it works.

True, but SQLite is not recommended in production settings, and is quite often the source of Nextcloud slowdowns, in my experience. A dedicated DB is the first thing I recommend for a production Nextcloud instance.

Oh and to be clear, in this instance, “production” means “people depend on this”, be that your family group, team/department, fraternal order, church group, etc. as opposed to “I’m just playing with this thing.”

‘dd’ works, but I prefer ‘shred’. It does a DoD multi-pass shred by default, so I usually use ‘shred -vn1z /dev/(drive)’. That gives output, does a one-pass random write followed by one-pass zero of the disk. More than that just wastes time, and this kinda thing takes hours on large spinners. I also use ‘smartmontools’ to run SMART tests against my drives regularly to check their health.

A named volume for the config directory for one.

Take it off the charger and see if you get the claimed battery life. Maybe you will, or maybe your 3+ hours of battery time runs out in less than one.

Only if you’ve got it cranking all day. I’ve got a couple of Tiny (they’re Micro, which is the same thing) systems that are silent when idle and nearly silent when running less than a load avg of 5. It’s only if I try to spin up a heavy, CPU-bound process that their singular fan spins fast enough to be noticable.

So don’t use one as a Mining rig, but if you want something that runs x64 workloads at 9-20 watts continuously, they’re pretty good.

If your requirement is a 3.5" drive bay, then maybe check out some of the SFF form factors, like an HP Elitedesk SFF 800 (not the mini/micro). It has the same hardware as the mini, takes the same amount of power, but has a space for a 3.5" disk and a slimline optical disc. It’s bigger than a NUC, but smaller than a tower.

It probably didn’t. What’s probably happening is that when Debian starts, it loads power management, while being in the BIOS/UEFI still has everything at max.
