Which feature of Datadog provides access to historical performance metrics?

The feature that provides access to historical performance metrics is Dashboards. Dashboards in Datadog are designed to visualize and monitor a variety of metrics and logs over time. They allow users to create custom views that can display historical performance data, helping teams understand trends and analyze the performance of applications and infrastructure over specific periods.

Dashboards can aggregate metrics from different sources, enabling users to correlate various performance indicators effectively. This visualization helps in tracking the historical trends of metrics such as response times, error rates, and resource utilization, making it easier to identify issues, assess the impact of changes, and plan for future capacity needs.

The other features serve different purposes; for instance, APM focuses on application performance monitoring to trace requests across services. Monitors are used to set up alerts based on metrics conditions, and Integrations connect with other tools or services but do not specifically aggregate historical metrics in a visual format like dashboards do. Hence, dashboards are the primary feature for accessing historical performance metrics in Datadog.
