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.

The items we have used so far were collecting data from some Zabbix agent or SNMP device. It is also possible to reuse this data in some calculation, store the result and treat it as a normal item to be used for graphs, triggers, and other purposes. Zabbix offers two types of such items:

  • Calculated items require writing exact formulas and referencing each individual item. They are more flexible than the aggregate items, but are not feasible over a large number of items and have to be manually adjusted if the items to be included in the calculation change.

  • Aggregate items operate on items that share the same key across a host group. Minimum, maximum, sum, or average can be computed. They cannot be used on multiple items on the same host, but if hosts are added to the group or removed from it, no adjustments are required for the aggregate item.

Calculated items

We will start with calculated items that require typing in a formula. We are already monitoring total and...
