Datadog's Log Explorer now offers subqueries to facilitate easier log correlation across multiple sources, enabling organizations to quickly investigate bugs for remediation, gauge the impact of a security breach, and identify key users. Subqueries allow users to filter logs with nested queries, overcoming common challenges such as fragmented data and tedious manual processes. By using subqueries, teams can surface critical data needed to troubleshoot issues, understand user behavior, and respond to security threats in real-time.
