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 SSH


Another way to extend our Zabbix server to do some checks is by making use of Secure Shell (SSH). SSH checks will be launched from the server with the need of a Zabbix Agent.

Getting ready

For this example, we just need a Zabbix server properly configured and a host that we can use to connect to by making use of SSH.

How to do it…

When you log in with SSH, you have to provide a username and a password in Zabbix to log in to the host that we want to monitor. This must be done in the GUI in plain text. An alternative to this is the use of SSH keys.

  1. The first thing we have to do in the Zabbix_server.conf file is to look for the option SSHKeyLocation and enable it and add a path for the location of our SSH key files. Add the following line to the config file.

    SSHKeyLocation=/home/zabbix/.ssh
  2. First edit the /etc/passwd file and give a home folder to the user zabbix:

    zabbix:x:500:500::/home/zabbix:/sbin/nologin
  3. Next, create the directory on the server. This can be done by running the following...
