Help troubleshoot Unraid server shutting down (Version: 6.12.4)

[schreibman]

Hello, 

I've had my Unraid server poweroff unexpectedly a couple of times.   Can you point me to the correct logs that I can inspect to help identify the root cause?

For example, is there a log I can check to see if the UPS sent a poweroff signal?

Are there other logs I can look at to help resolve this issue?

I've had to manually power on the server to resolve.

Looks like that was it!

Found it:

    Line 123075: Oct 17 08:37:03 Tower apcupsd[13439]: Power failure.
    Line 123076: Oct 17 08:37:03 Tower apcupsd[13439]: Battery power exhausted.
    Line 123093: Oct 17 08:37:13 Tower apcupsd[13439]: Power is back. UPS running on mains.

For future reference you might want to enable the syslog server if you want to capture a persistent log that survives a reboot so you can see what was leading up to an unexpected shutdown.
