The rich monitoring capabilities needed by a solution to participate in the quadrant is way beyond what most people consider possible with traditional flow exports. Today however, this has changed.

In fact, for the most part, I agree that statistically, sampling can be as accurate as rolling a dice 1296 times and expecting exactly 216 matches for each of the 6 possible outcomes. Well, I doubt it. When …
