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

Aggregate checks


Running individual checks has been great so far, but they are just checks on one system. What if you would like to know the total CPU load of a group of servers? For example, when you are running a cluster of servers? For this we can make use of the aggregated checks in Zabbix.

Getting ready

To be able to finish this recipe successfully we need our Zabbix server with a few Linux hosts installed and properly configured.

How to do it …

  1. First, we create a new host called linuxgroup, for the agent IP address we can just put 0.0.0.0 and add it in a fictive hostgroup or for example, Discovered hosts.

  2. Next, we create a new group (Configuration | Host groups) "aggregated" and we add two or more Linux hosts in this group.

  3. Now we create an active item "system.cpu.load[percpu,avg1]" in a new template that we can link to all our hosts available in our "aggregated" group.

  4. The next step is to create a new template for example aggregated-linux and link this template to our fake host linuxgroup...
