Metric Correlations is a new feature introduced by Datadog to help users pinpoint possible root causes of issues in their systems more efficiently. By automatically searching for correlated metrics, it enables users to launch investigations from multiple entry points and discover the full extent of a problem and its side effects. The feature groups results by source to help identify components involved in an issue and provides detailed views of correlations found from other sources, allowing users to drill down into specific areas of investigation. Additionally, Metric Correlations allows users to adjust their search area, include custom metrics, and scope their search to specific environments or services. With this feature, users can speed up their investigations and understand the scope of any issue more quickly.
