Which Zabbix feature allows users to visualize data trends over time?

Graphs in Zabbix are a powerful feature that enables users to visualize data trends over time effectively. This visualization is crucial for understanding how monitored metrics change and behave, allowing for quick identification of patterns, anomalies, and the overall performance of systems being monitored.

Graphs compile time-series data collected from various items, displaying this information in a clear and interpretable format. Users can customize graphs by selecting specific metrics, time periods, and aggregation methods to gain better insight into their data. This allows for efficient monitoring and trend analysis, which can lead to informed decisions about infrastructure and resource management.

In contrast, alerts are notifications triggered by specific events or conditions, but they do not display data trends. Triggers are conditions that define when an alert should be sent or an action taken based on specific thresholds being crossed, and while they can be instrumental in monitoring system health, they won't provide visualizations. Actions automate responses based on triggers but do not visualize data themselves. Each of these features plays a distinct role in the monitoring ecosystem, but graphs are specifically designed for trend visualization.
