Sometimes my OPNsense box reboots itself.
I don't know what triggers it.
How do I:
1. configure OPNsense to record all reboot logs to a file I can later review? (e.g. save crash dump/data/errors and boot logs)
2. troubleshoot unplanned reboots?
Thanks.
Not exactly what you're after but boot logs are saved normally. They get rotated but you can go back a bit in /var/log/ directory. But, it might not have a record of the trigger i.e. a crash dump. That needs to be configured and I haven't had the need to look at the way for OPN.
One thing I used for a different system I had to troubleshoot for the same thing is I created a small VM on the same network and configured as a syslog target. There I was able to see the trigger. Hope it helps.
You can look into these logfiles:
/var/log/dmesg.today
/var/log/dmesg.yesterday
If the OPNsense randomly reboots I would grep them for "panic".
In the GUI there's also the /crash_reporter.php
