Opensense router crashed

[DoubleSpeed]

I'm running Opensense on a Intel(R) Core(TM) i5-5250U CPU @ 1.60GHz (2 cores, 4 threads) with 8GBs RAM

Versions
OPNsense 24.7.8-amd64
FreeBSD 14.1-RELEASE-p6
OpenSSL 3.0.15

and everything seems good however without warning Opensense crashed and I lost all access to this as well as the internet access etc.

I power cycled the device and this restarted and reconnected to the internet etc and all seems to be running normally again.

Can anyone advise what logs I should check to look for the possible root causes of this in case it happens again?

Also is there a configuration for Monit that will reboot the device in the event of major failures in services etc?
