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

Global regular expressions


Now that we know about some of the automation features, let's take a look at a feature in Zabbix that allows us to define regular expressions in an easier—and sometimes more powerful—way. This feature can be used in low-level discovery, discussed here, and other locations.

There are quite a lot of places in Zabbix where regular expressions can be used—we already looked at icon mapping in Chapter 9, Visualizing the Data with Graphs and Maps, and log filtering in Chapter 11, Advanced Item Monitoring. In all these places, we defined the regular expression directly. But sometimes, we might want to have a single expression that we could reuse, or the expression could be overly complicated when typed in directly. For example, our filtering of loopback interfaces earlier was not the most readable thing. This is where global regular expressions can help. Let's see how we could have used this feature to simplify that filtering. Navigate to Administration | General, choose...
