No doubt, this book would not have been possible without the support of the competent technical body of Unirede Soluções Corporativas. These brave warriors were indispensable, discussing and supporting the testing and proof of concepts that were performed to support the content of several chapters. Then, there is also a special mention for Mr. Alisson Oliveira and Mr. Thiago Melo, who have always been willing and open, even without knowing the main objective of the proposed discussions and tests.

The list of thanks is actually huge, ranging from Leandro Santos, who gave me the opportunity to enter the world of ICT in 1994, to all the colleagues and bosses who came across me and helped me build the professional profile I have today. I also extend my thanks to Mr. Alexei Vladishev. In 2008, he boarded a plane in Latvia and disembarked in Brazil for the first official training in this region, and also believed in the goal of Unirede Soluções Corporativas—to become the world's best partner of Zabbix SIA. Then, thanks to Mr. Ricardo Santos (http://zabbixzone.com), who was initially invited to write this book but kindly passed on this challenge to me. I also wish to thank the active participants of the Zabbix Brazil community. They have served as the basis for a lot of information and statistical data given in this book. Not least to mention for writing this book are the competent professionals from Packt Publishing. They showed a lot of patience and supported and encouraged me, and I can only imagine how hard it must have been to deal with all the delays and disagreements that occurred during the process.

An honorable mention goes to our translator, Thiago Pitoni, for being part of this project, always suggesting new approaches, and rephrasing many sentences. Most importantly, thanks goes to my family, who were deprived of my attention and presence for a long period of time but never ceased to encourage and support me in this project.
