/var/log/kern.log has:

Dec 14 22:37:30 ray-desktop kernel: [539775.847567] mce: [Hardware Error]: Machine check events logged
Dec 14 22:40:09 ray-desktop kernel: [ 0.000000] microcode: microcode updated early to revision 0x8e, date = 2018-03-24
Dec 14 22:40:09 ray-desktop kernel: [ 0.000000] Linux version 4.15.0-42-generic (buildd@lgw01-amd64-023) (gcc version 7.3.0 (Ubuntu 7.3.0-16ubuntu3)) #45-Ubuntu SMP Thu Nov 15 19:32:57 UTC 2018 (Ubuntu 4.15.0-42.45-generic 4.15.18)
...


But Ubuntu 18.04 has no mcelog command or /var/log/mcelog file.



So where are the events logged?



Or more generally, how do I determine what hardware failed?
