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.

The low-level discovery protocol


The low-level discovery protocol provides an automated way to create items, triggers, and graphs for different entities on a computer. For instance, Zabbix can automatically start monitoring filesystems or network interfaces on your machine without the need to create items for each filesystem or network interface manually. Actually, the results found thanks to the discovery can trigger many different actions, such as even removing unneeded entities such as items and so on. This functionality gives a lot of flexibility to our monitoring system. Zabbix, indeed, lets you customize and create a brand-new low-level discovery rule to discovery any type of Zabbix entity.

Let's see which one is the output used by a low-level discovery item such as vfs.fs.discovery. To see the output, we can simply run the following command:

$ zabbix_get –s 127.0.0.1 –k vfs.fs.discovery
{"data":[
{"{#FSNAME}":"/","{#FSTYPE}":"rootfs"},
{"{#FSNAME}":"/proc","{#FSTYPE}":"proc"},
{"{...
