Instrumentation

How many applications in production are having instrumentation code in it?
Yeah.... you can count it. That's the state of current applications handling millions of request, running trillions of transactions...

It's something akin to an airplane not having a blackbox. You won't ever know what went wrong with it in case of any disaster.

More to come....
