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 benefits


With our first proxy configured, let's discuss in more detail its operation and the benefits it provides. Let's start with the main benefits:

  • A proxy collects data when the server is not available

  • A proxy reduces the number of connections to and from remote environments

  • A proxy allows us to use incoming connections for polled items

We talked about the proxy retrieving configuration data from the server, and we talked about it having a local database. The Zabbix proxy always needs a local database, and this database holds information on the hosts the proxy is supposed to monitor. The same database also holds all the data the proxy has collected, and if the server cannot be reached, that data is not lost. For how long? By default, data is kept for one hour. This can be configured in the zabbix_proxy.conf file, the ProxyOfflineBuffer parameter. It can be set up to 30 days, but beware of running out of disk space, as well as of the potential to overload the Zabbix server when connectivity...
