Datadog's AWS integration allows users to automatically collect metrics from multiple AWS services, including EBS, and correlate them with data from other services in their environment. Users can also install the Datadog Agent on their instances to gather system-level metrics from volumes, including disk usage, at 15-second resolution. This enables a fully unified monitoring platform for applications and infrastructure. The integration allows users to create customized dashboards that meet specific monitoring needs, visualize key metrics, and set up alerts for potential issues such as increased disk read operations or unexpected instance behavior. Additionally, the Datadog Agent provides benefits like higher resolution metrics, device naming consistency, and advanced alerting features like anomaly detection and forecasting. Users can start monitoring their EBS volumes with Datadog by enabling the AWS integration or installing the Agent on their instances.
