Datadog's Flex Logs offers a cost-efficient solution for storing and analyzing large volumes of logs without driving up expenses, by decoupling storage and compute costs. This system allows teams to store logs for up to 15 months and choose compute sizes based on their querying needs. Flex Logs works in tandem with Standard Indexing, allowing teams to determine which logs are needed for real-time troubleshooting and which can be retained for ad hoc analysis. The Flex Logs Controls page provides new compute usage graphs that help monitor performance, identify slowdowns, and optimize usage. These insights allow teams to manage their compute capacity, identify slow queries, and adjust storage strategies according to log importance and volume. Best practices include improving query efficiency, optimizing dashboards, and scaling compute size to enhance performance and responsiveness. Flex Logs thus provides transparency and flexibility in log management, offering a 14-day free trial for new users to explore its capabilities.
