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.

Discovering hosts


A third way to link templates to hosts is to let the server do it automatically by combining Zabbix's host-discovery facility with discovery actions.

Zabbix's discovery facilities consist of a set of rules that periodically scan the network to look for new hosts or disappearing ones according to predetermined conditions.

The three methods that Zabbix can use to check for new or disappeared hosts, given an IP range, are:

  • The availability of a Zabbix agent

  • The availability of an SNMP agent

  • Response to simple external checks (FTP, SSH, and so on)

  • These checks can also be combined, as illustrated in the following example:

As you can see, when enabled, this rule will check every hour in the IP range 192.168.1.1-255 for any server that:

  • Responds to an ICMP ping probe

  • Has a correctly configured Zabbix agent that will return a value when asked for the system.uname item

  • Has an SMTP listening port, which is usually associated with a mail server

As usual, with all things Zabbix, a discovery...
