Yeah so that's what I thought but it came up in a conversation and I
wanted to go to "the source" to get my information before stating what I
thought was true. My understanding of perfmon2 was such that I didn't
think it could do what I currently do w/ kernel probes.
Sorry to derail the conversation, just wanted to get an answer from the
horse's mouth.

Where did you hear that? The two technologies aren't substitutes
for one another.
