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.

Checks with Telnet


In this setup, we will see how to set up a check with Telnet and Zabbix. I personally don't see any reason for using Telnet anymore these days as there are plenty of other secure alternatives (Example, SSH). But just for the sys admin who likes to live on the edge or for the sys admin that has no other choice because of a company policy, this is it. (Remember that Telnet is not encrypted, so everybody can read your data!)

Getting ready

To make this setup work, all we need is a properly setup Zabbix server and a host with or without Zabbix agent as the check is initiated by the Zabbix server.

How to do it…

  1. First on the host we need to be sure that we can connect with Telnet so we have to install a Telnet server. This can be done by running the next command:

    # yum -y install telnet-server
    
  2. On the Zabbix server, we have to install Telnet, of course. This can be done by running the install telnet command:

    # yum -y install telnet
    
  3. Back on our client we have to edit the xinet.d file...
