Install and Configure Zabbix Agents for Windows and Linux Hosts

Zabbix agent is deployed on a monitoring target to actively monitor local resources and applications (hard drives, memory, processor statistics, etc.).

The agent gathers operational information locally and reports data to Zabbix server for further processing. In case of failures (such as a hard disk running full or a crashed service process), Zabbix server can actively alert the administrators of the particular machine that reported the failure.

Zabbix agents are highly efficient because of the use of native system calls for gathering statistical information.

Passive and active checks

• Passive checks - Zabbix agent responds to a request from Zabbix server (or proxy). For example, the server requests data (e.g., CPU load), and the agent returns the result.
• Active checks - Zabbix agent collects and sends data without waiting for a request from Zabbix server (or proxy). First, it retrieves a list of monitoring items from server (CPU load, available memory, etc.), then collects the required data and periodically sends new values back to it.

The agent check type is configured by selecting the respective monitoring item type. Zabbix agent processes items of type "Zabbix agent" or "Zabbix agent (active)".
