How to install Zabbix Agent on Debian 11 Bullseye

If you already have a Zabbix server installed and want to monitor any target machine or server then to make things easy use its Agent. Here in this tutorial, we will learn the steps to install Zabbix Agent on Debian 11 Bullseye.

The Zabbix agent is part of the whole open-source network monitoring tool offered by the developers of it. That is required to actively monitor a target/server or to query its resources (HDD, RAM, CPU, database, general statistics, network, etc.). The agent runs as a service on the server or desktops. It is not necessary because the Zabbix server can also collect information using, for example, SNMP, SSH, IPMI, macros, etc. After that, the admin can evaluate the data of various machines using the web interface. Based on the information provided by the Agent the server part of Zabbix can generate alerts in a case of emergency to admins via various channels (email, SMS, etc.).

Zabbix Agent is available for a wide range of platforms Linux, IBM AIX, FreeBSD, NetBSD, OpenBSD, HP-UX, Mac OS X, Solaris: 9, 10, 11, Windows 11/10/and all desktop and server versions since 2000.
