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.

The SSH monitoring functionality provided by Zabbix, since it's server-triggered and even agentless, is quite useful. This specific functionality is precious as it allows us to run remote commands on a device that doesn't support the Zabbix agent. This functionality is tailor-made for all the cases where, for support reasons, we can't install a Zabbix agent. Some practical cases are given as follows:

  • A third-party, vendor-specific appliance where you can't install software

  • A device that has a custom-made operating system or a closed operating system

To be able to run SSH checks, Zabbix needs to be configured with SSH2 support; here, the minimum supported libssh2 is Version 1.0.0.

SSH checks support for two different kinds of authentication:

  • SSH with username and password

  • Key file based authentication

To use the username/password pair authentication, we don't need to do any special configuration; it is enough to have compiled Zabbix with the SSH2 support.
