What is the four-step data flow in Zabbix?

The four-step data flow in Zabbix is accurately represented by the sequence Item > Trigger > Event > Conditions. This progression outlines the flow of data and alerts in the monitoring process.

1. Item: This represents the fundamental building block of data collection in Zabbix. An item is a specific piece of information that Zabbix collects from monitored hosts, such as CPU load, memory usage, or network traffic.

2. Trigger: Once data is gathered through items, triggers come into play. They analyze the collected data based on predefined conditions. A trigger evaluates the values from the items against a threshold or a defined expression. If the conditions set in the trigger are met (e.g., CPU load exceeds 90%), the trigger generates an alert.

3. Event: When a trigger's conditions are satisfied, it generates an event. Events are essential indicators of changes in the state of monitored entities. They can represent issues or acknowledgments depending on their definitions. These events are logged and can be used to track the history of problem occurrences.

4. Conditions: Following the creation of an event, conditions can be applied to determine the next steps. These conditions are often used in actions that notify users or execute
