Would you like to learn how to use Zabbix Auto Discovery feature to detect computer with the Zabbix agent installed located on the internal network. The system will detect those computers and automatically add them to a specific group of hosts.

• Zabbix version: 3.4.12

The Auto Discovery feature allows the Zabbix server to periodically scan the network for computer or devices using the Zabbix agent and take pre-defined actions upon discovery of those devices.

It is important for you to understand that your Zabbix server will only find devices which the Zabbix agent installed and pre-configured to accept connections from your Zabbix server.

If you don't know how to install and configure the Zabbix agent on a computer running Windows or Linux, please take a look at our Zabbix tutorial list.

Zabbix Discovery operations

In our example, the Zabbix server will scan the network 192.168.100.0/24 and try to find devices with the Zabbix agent installed every 1 hour.

If the Zabbix server finds a device using the Zabbix agent it will add this device to the Discovered hosts group.

Zabbix Discovery Hostname

Keep in mind that your Zabbix server Must be able to translate the devices IP address to the device name.

If your Zabbix server is not able to translate the computer IP address to the hostname, it will create a host using the IP address of the device instead of using the hostname.

Zabbix Discovery IP Address

If you want, you may also configure the Zabbix server to assign a template during the discovery process.

Congratulations! You have configured the Zabbix Auto Discovery feature successfully.
