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

Overview


For Zabbix communication encryption, two types are supported:

  • Pre-shared key

  • Certificate-based encryption

The pre-shared key (PSK) type is very easy to set up but is likely harder to scale. Certificate-based encryption can be more complicated to set up but easier to manage on a larger scale and potentially more secure.

This encryption is supported between all Zabbix components—server, proxy, agent, and even zabbix_sender and zabbix_get.

For outgoing connections (such as server-to-agent or proxy-to-server), only one type may be used (no encryption, and PSK or certificate-based). For incoming connections, multiple types may be accepted. This way, an agent could work with encryption by default for active or passive items from the server and then work without encryption with zabbix_get for debugging.

Backend libraries

Behind the scenes, Zabbix encryption can use one of three different libraries: OpenSSL, GnuTLS, or mbedTLS. Which one to choose? If using packages, the easiest and safest is...
