Every dashboard has a blind spot. This book is about finding yours before "production" does.

Drawing on seventeen years of performance engineering and QA leadership across telecom, security, and enterprise media products, Saurabh Kumar shares the lessons that came from real failures, not textbooks.
Each chapter opens with what actually happened, then distills the habit that came out of it; practical, specific, and immediately usable whether you're tuning JMeter scripts, reading Prometheus alerts, or leading a QA team through growth without losing reliability.

Inside, you'll learn:
Why averages hide the exact problems performance testing exists to catch, and what to plot instead
How to design dashboards for the audience actually reading them
Where compatibility issues hide when testing across AWS, VMware, Hyper-V, and OpenStack
What changes when your product happens live, and correctness becomes a matter of milliseconds and human perception
How to scale a QA team without diluting the discipline that made it good in the first place

This is a short, direct guide for performance engineers, QA leads, and anyone who's been handed "test this before we ship it" without much guidance. Nothing here is theoretical.
