HomeCentOSHow to Install and configure Zabbix agent 3.4 on CentOS 7
(Last Updated On: October 16, 2018)

In our previous guide, we covered the installation of Zabbix Server on Ubuntu 18.04. This is a continuation guide on Zabbix monitoring of your entire Infrastructure – Linux systems, Windows servers, network routers, network switches e.t.c. So let’s get started with how to Install and configure Zabbix agent 3.4 on CentOS 7.

For Ubuntu servers, check How to Install and configure Zabbix agent on Ubuntu 18.04/16.04

How

Zabbix agent is a program developed in C. It runs on various supported platforms, including Linux, UNIX, and Windows. The work of Zabbix agent is to collect data such as CPU, memory, disk and network interface usage from a device. It has a small resource footprint considering that monitoring configurations are centralized on Zabbix server.

How Zabbix agent works

Zabbix agent can do both passive (polling) and active checks (trapping). The checks can be performed at an interval or based on specific times schedule. Here is the difference between passive and active checks:

Passive checks (polling):

  • Zabbix server (or proxy) requests a value from Zabbix agent
  • Agent processes the request and returns the value to Zabbix server (or proxy)

Active checks (trapping):

  • Zabbix agent requests from Zabbix server (or proxy) a list of active checks
  • The agent sends the results in periodically

The image below from Zabbix may help visualize passive and active checks in action:
