The Little Metrics Book

About the Book

This is a book about a subject I love. I wrote it so that metrics doesn't become a lost art only handled by just the infrastructure people, but to make it accessible so that anyone can become such an infrastructure person and that metrics can become a cross-cutting concern within a team or organization.

At the very least, I made sure to fill it with my distilled experience you should have in order to start on the right foot. This is the stuff you can't google for. I called it a _little book_, because I value your time, and I took the extra effort to carefully pick what goes in and what goes out, so I hope that the result is a book with zero bullshit, if I may be blunt.
