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

Performance considerations


Zabbix tends to perform nicely for small installations, but as the monitored environment grows, one might run into performance problems. A full Zabbix performance discussion is out of scope here, but let's discuss the starting points to having a healthy configuration and the directions for further research:

  • Monitor only what you really need, as rarely as possible, and keep the data only for as long as really needed. It is common to new users of Zabbix to use default templates as-is, add a lot of new items with low intervals...and never look at the data. It is suggested to clone the default templates, eliminate all that is not needed, and increase the intervals as much as possible. This involves trimming item lists, increasing intervals, and reducing history and trend-retention periods. There are also events, alerts, and other data—we will discuss their storage settings a bit later.

  • When using Zabbix agents, use active items. Active items will result in a smaller...
