re sampling: I'd thought capturing power line transients might best be done with a custom analog over voltage or under voltage threshold circuit that thats trigger a counter that measures the length of the glitch and stops when the power returns to within normal bounds. The logger gets interrupted and it reads the count. Might need a little distributed PIC to do it. The threshold under voltage or over voltage threshold would be such that could or would cause corruption, hangs or reboots in the CRio and other critical devices. The logger would record a "device Bridge PS undervoltage for X ms" event.

Overvoltage detection would immediately identify situations where the bridge or camera were accidently powered with 12v, both of which happened to us this year. Also our Crio rebooted a number of times, cause never absolutely confirmed.
