Determine shutdown cause (self.opnsense)

Hi all, I've got a cheap Celeron box running OPNSense and it's been pretty good so far, but I found twice that the device turned off at some point while I was at work, and I have been unable to figure out what's causing it.

The only change was that I enabled Monit to see if I could figure out what was causing crowdsec to stop sometimes but never ended up configuring anything. I've only been running it for a couple months though, so it's possible that that is not related.

I know that on a Mac (based on freebsd, right?) you can determine whether the shutdown reason was a hard shutdown, regular shutdown, or the power cable being unplugged. Is it possible to do that with OPNSense? I'd like to narrow it down to software or hardware ideally.

Final Update: it's the hardware, I think it was overheating in general, but also the SSD seems to have been dying and the ram wasn't particularly reliable, possibly due to the heat.

Good lesson not to buy the cheapest thing from AliExpress! My new box is working great.
