Overview of this book

Nowadays monitoring systems play a crucial role in any IT environment. They are extensively used to not only measure your system’s performance, but also to forecast capacity issues. This is where Zabbix, one of the most popular monitoring solutions for networks and applications, comes into the picture. With an efficient monitoring system in place you’ll be able to foresee when your infrastructure runs under capacity and react accordingly. Due to the critical role a monitoring system plays, it is fundamental to implement it in the best way from its initial setup. This avoids misleading, confusing, or, even worse, false alarms which can disrupt an efficient and healthy IT department. This new edition will provide you with all the knowledge you need to make strategic and practical decisions about the Zabbix monitoring system. The setup you’ll do with this book will fit your environment and monitoring needs like a glove. You will be guided through the initial steps of choosing the correct size and configuration for your system, to what to monitor and how to implement your own custom monitoring component. Exporting and integrating your data with other systems is also covered. By the end of this book, you will have a tailor-made and well configured monitoring system and will understand with absolute clarity how crucial it is to your IT environment.

Chapter 2. Distributed Monitoring

Zabbix is a fairly lightweight monitoring application that is able to manage thousands of items with a single-server installation. However, the presence of thousands of monitored hosts, a complex network topology, or the necessity to manage different geographical locations with intermittent, slow, or faulty communications can all show the limits of a single-server configuration. Likewise, the necessity to move beyond a monolithic scenario towards a distributed one is not necessarily a matter of raw performance, and, therefore, it's not just a simple matter of deciding between buying many smaller machines or just one big, powerful one. Many DMZs and network segments with a strict security policy don't allow two-way communication between any hosts on either side, so it is impossible for a Zabbix server to communicate with all the agents on the other side of a firewall. Different branches in the same company or different companies in the...
