Vincent Bumgarner has been designing software for over 20 years, working with many languages on nearly as many platforms. He started using Splunk in 2007 and has enjoyed watching the product evolve over the years. While working for Splunk, he has helped many companies train dozens of users to drive, extend, and administer this extremely flexible product. At least one person in every company he has worked with has asked for a book, and he hopes that this book will help fill their shelves.
