The Zabbix agent is made available as part of the comprehensive open-source network monitoring utility that was developed by the program’s creators and is made available by those developers. That is required in order to carry out active monitoring of a target or server, as well as to query the resources that the target or server contains. The agent can function as a service on either the central server or on each of the individual workstations.
It is not necessary because the Zabbix server is able to gather information via other techniques as well, such as SNMP, SSH, IPMI, macros, and so on. As a result, it is possible to collect the information using any of these methods. After that, the administrator will be able to make use of the web interface in order to investigate the data coming from the numerous computers.
In the event that there is a crisis, the server component of Zabbix is able to send alerts to administrators via a number of different channels. These alerts are generated on the basis of the information that is provided by the Agent. Zabbix Agent is suitable for use on a wide variety of computer operating systems.
Install Zabbix Agent on Debian 10/11 Bullseye
- To begin, we have to check to see if all of our system packages have been brought up to date. Launch the following command from within your Debian system by opening a terminal or connecting via SSH:

- sudo apt update
- sudo apt install zabbix-agent
Configure the Zabbix Agent
- When the installation is finished, the Zabbix agent needs to have its communication settings configured so that it may talk to the Zabbix server. Launch a text editor and open the Zabbix agent configuration file as follows:
- sudo nano /etc/zabbix/zabbix_agentd.conf
Final Words
You have done an excellent job of installing and configuring the Zabbix agent on your system that is based on Debian. Now that communication with the Zabbix server has been established, the agent is prepared to supply monitoring data. You will be able to acquire useful insights into the performance and health of your infrastructure if you monitor your systems with Zabbix.
