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.

Understanding the data flow for Zabbix items


A Zabbix item can be understood by its bare essentials—an identifier, data type, and associated host. These are the elements that are generally more useful for the rest of Zabbix's components. The identifier (that's usually the name and the associated item key) and the associated host are used to distinguish a single item among the thousands that can be defined in a monitoring environment. The data type is important so that Zabbix knows how to store the data, how to visualize it (text data won't be graphed, for example), and most importantly, what kind of functions can be applied to it in order to model triggers and the process further.

Tip

The item's name is a descriptive label that is meant to be easily read, while the item's key follows a specific syntax and defines exactly the metric that we want to measure.

Two other very important elements that are common to all the items are the history (and trends) retention period and item type. We already...
