Foreword

Zabbix performance tuning is an important topic when it comes to the use of Zabbix to monitor a large number of network devices. I think most Zabbix users have experienced performance-related issues in some way or the other. These can be because of non-optimal configuration parameters of the Zabbix server or proxy, use of default settings for MySQL, the PostgreSQL configuration, or other reasons.

This book is quite unique. It focuses only on performance-related topics, and does so extremely well. Luciano is one of the most knowledgeable and active Zabbix users and community members. The first time I met him was in Brazil in 2008, and I was impressed by his deep understanding of Zabbix's internals and the great ideas that he always has. He has a unique combination of real-world experience and a strong technical background.

Regardless of how you use Zabbix and the size of your deployment, this book will give you enough information to be confident that Zabbix will deliver the level of scalability you need.

Read it; you won't be disappointed!
