Installing Zabbix Agent on Ubuntu 20.04 with 3 simple steps.

1. Introduction

In the previous tutorial, AZDIGI showed you how to install Zabbix 6.0 on Ubuntu 20.4 server. And in this article, AZDIGI will continue to introduce and guide you on Zabbix’s monitoring with the entire Infrastructure – Linux systems, Windows servers, network routers, network switches, etc.

Zabbix Agent is a program developed in C language. Zabbix Agent is installed on servers or client-side devices. Thereby, Zabbix Agent will collect the necessary information from the client computer that needs to be monitored, checked and collected data related to CPU, Memory, Disk and Network interface… or other administrator requirements, then send the results back to Zabbix Server.

How Zabbix Agent works

Zabbix Agent can perform both passive testing (polling) and active testing (trapping). Testing can be done at intervals or based on a time-specific schedule. This is the difference between passive and active testing.

  • Passive test: Zabbix Server will send the request to Zabbix Agent. The Zabbix Agent will process that request and return the result to the Zabbix Server.
  • Active test: This type makes the processing request more complicated. The Zabbix Agent will have to retrieve the list of items to be processed for independent processing. Then, it will periodically return the results to Zabbix Server.

The image below is a detailed description of Zabbix Agent, so you can visualize the passive and active testing activities.
