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.

Getting ready

If you want to do this exercise, then you need a Zabbix server that is properly setup and linked to the standard Linux template. Of course, you can alter the items that we have used and use your own if you like.

How to do it…

  1. The first step is to go to the Zabbix server and create a new item on the host or in a template.

  2. Give the item a name, something such as % free on root.

  3. Select the Type, Calculated.

  4. Fill in the Key with a unique name, example free.root.

  6. Select Numeric (float) as Type of information.

  7. And in the Units field, place %.

  8. Those are the options we need to build our calculated item, so you can save it or give it an application first.

  9. Next we can...
