>In memtesting we boot a custom MemTest86 image and monitor it while it completes a full pass. Our custom version of MemTest86 changes the color of the failure message to red which allows us to detect trouble. We’ve hacked together a Ruby script that retrieves a console screenshot via IPMI and checks the color in the image to determine if we’ve hit a failure or not.

Wow. Why is this done this way? Is there no other way to receive hardware memtest info? I would have thought that there was some way to revive machine serial output status in a datacenter.
