Using Telemetry in Anger

I think Sasha has actually probably has more experience with telemetry than maybe any of us. I've used it that's about it, but never in anger, you know? That does I feel where most of the valuable learnings come from when you use something in anger. You'll get an idea at least about what that something's happening, but don't have an idea about which part of your query is giving the problem. It's a great tip.
