What does "Zabbix agent active mode" signify?

"Zabbix agent active mode" signifies that the agent can send data to the Zabbix server proactively, rather than waiting for the server to request that data. In this mode, the agent is responsible for determining what data it will send, allowing for more efficient use of resources and minimizing unnecessary communication between the agent and the server. The agent can gather metrics and send them to the server at specified intervals, ensuring that the server receives updated information without the need for constant polling.

This mode is beneficial in environments where network bandwidth is a concern, as it avoids the overhead associated with repeated server requests. The active mode allows for greater flexibility in data collection and is particularly useful for capturing metrics from systems that may not be frequently polled or where data needs to be reported immediately based on certain triggers or events.
