Another metric that frequently came up during outreach was any sudden 
increase in disk latency, usually indicating that you have between one 
and 24 hours to replace the device. I am curious what people are doing 
now to determine such changes in latency and where they feel such 
monitoring should exist in the stack.

As for SNMP and friends, I consider those way up the stack with tools 
like smart(8) simply providing a building block.
