Where are machine check events logged?

The warning will be logged by a “Machine Check Event logged” notice in your system logs, and can be later viewed via some Linux utilities. A fatal MCE will cause the machine to stop responding and the details of the MCE will be printed out to the system’s console.

What is Machine Check event?

A Machine Check Exception (MCE) is a type of computer hardware error that occurs when a computer’s central processing unit detects a hardware problem. Your computer experienced a hardware error and the kernel logged an event in a buffer. You can use mcelog to log and view the machine check events.

What is machine check error?

Machine Check Exception (MCE) is an error that occurs when a computer’s CPU detects a hardware problem. Typically, the impending hardware failure will cause the kernel to panic to protect against data corruption. Machine checks can indicate failing hardware, system overheats, bad DIMMs, or other problems.

What is Mcelog in Linux?

mcelog is a tool that helps in finding out hardware errors especially memory, IO, and CPU hardware errors and supports both the x86 and x86_64 platforms since Kernel 2.6 . From the ( the official website for mcelog ), The mcelog daemon accounts memory and some other errors errors in various ways.
