But there is an alternative that is quite fast and even shows the booted kernel version: # last reboot -F -n10 reboot system boot 6.5.11-7-pve Thu Apr 11 16:31:24 2024 still running reboot system boot 6.5.11-7-pve Thu Apr 11 16:29:17 2024 - Thu Apr 11 16:31= :12 2024 (00:01) reboot system boot 6.5.11-7-pve Thu Apr 11 16:25:41 2024 - Thu Apr 11 16:31= :12 2024 (00:05) ... Furthermore, as simulated and visible above, a duplicated "until" field hints that the earlier system boot (16:25:41) crashed unexpectedly (sometim= e before the next boot at 16:29:17). Limiting the output to 10 lines seems reasonable for most cases. > > > >=20 > > > >=20 > > > > As here you get much more info, e.g. about (recent) frequent reboot= s. > > > >=20 > > > > Please remember to add this also to the PMG and PBS reports.=20 > > > >=20 > > > > > > > > =C2=A0 'pveversion --verbose', > > > > > > > > =C2=A0 'cat /etc/hosts', > > > > > > > > =C2=A0 'pvesubscription get', > > > >=20
