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

Proxy limitations


While proxies have many benefits, they do have some limitations, too. Well, pretty much one main limitation—they are only data collectors. If the server cannot be reached, the proxy cannot do independent notifications. They can't even generate events; all logic regarding triggers is processed on the server only. Remember, proxies do not process events, send out alerts, or execute remote commands. Remote commands, discussed in Chapter 7, Acting upon Monitored Conditions, are currently scheduled for Zabbix 3.2—but one would have to see that version released to be sure about such a feature being implemented.

Proxy operation

Let's talk about how proxies operate a bit. We'll cover three things here:

  • Synchronization of the configuration

  • Synchronization of the collected data

  • Operation during maintenance

By default, proxies synchronize the configuration once per hour, and this period can be set in the zabbix_proxy.conf configuration file. Look for the parameter named ConfigFrequency...
