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 that can disrupt an efficient and healthy IT department. This course is for administrators who are looking for an end-to-end monitoring solution. It will get you accustomed with the powerful monitoring solution, starting with installation and explaining the fundamentals of Zabbix. Moving on, we explore the complex functionalities of Zabbix in the form of enticing recipes. These recipes will help you to gain control of your infrastructure. You will be able to organize your data in the form of graphs and charts along with building intelligent triggers for monitoring your network proactively. Toward the end, you will gain expertise in monitoring your networks and applications using Zabbix. This Learning Path combines some of the best that Packt has to offer in one complete, curated package. It includes content from the following Packt products: Zabbix Network Monitoring-Second Edition Zabbix Cookbook Mastering Zabbix-Second Edition

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"},
