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

More advanced triggers


Sometimes triggers in Zabbix are too sensitive and you get notifications all the time because of quick repeated status changes; this is what we call flapping. This could be for example a swap file that is growing and shrinking all the time, making Zabbix send notifications that there is not enough free space left and a few seconds later going back in an OK state because there is enough space again to come back in alarm once again, a few seconds later. Another example of flapping could be the CPU load going over and under the threshold every x number of seconds. Let's see how we can solve this.

Getting ready

For this recipe, we only need a Zabbix server with an agent installed on the Zabbix server or some host and of course access with a super administrator account, like the one that comes standard with the installation.
