Can you count the letter o in:
Q: See ECC correction count Im curious as to whether or not theres some performance counter that will log the number of ECC corrections required, that could perhaps be tracked as an early indicator of memory failure. I imagine it would theoretically be accessible in the same way that page faults from the tlb are reported to the OS?
Solutions for Windows or FreeBSD and Linux are welcome.

A: For Linux:
Install mcelog and it will log all errors into /var/log/mcelog.log
You can also look at the Linux sysfs, see the EDAC documentation for the relevant information: https://www.kernel.org/doc/Documentation/edac.txt

A: Most hardware handles this logging natively. For example HPs iLO baseboard management controller spouts ECC memory error activity to its Integrated Management Log.
So, the generic answer for the generic question is: Check your hardware management systems capabilities and resources.

A: Or read this page, it talks about using Linuxs kernel EDAC to query the memory controller, and provides some examples scripts.: http://www.admin-magazine.com/Articles/Monitoring-Memory-Errors

The total number of "o"s in that passage is eighty-three.
