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.

These checks do not require any specialized agent running on the remote end and only rely on basic network protocols such as Internet Control Message Protocol (ICMP) and TCP to query monitored hosts.

Note

Host-availability icons only cover the Zabbix agent, SNMP, JMX, and IPMI status, that is, things where we expect the response to arrive. Our expectations for simple checks could go both ways—an open port could be good or bad. There is no status icon for simple checks.

Let's create a very basic check now. Go to Configuration | Hosts, click on Items next to Another host, and click on Create item. Use the following values:

  • Name: Enter SMTP server status

  • Type: Select Simple check

  • Key...
