Datadog Log Management allows users to centralize their log data and perform advanced analytics on it. Users can use formulas and functions to manipulate and analyze their logs, enabling them to answer complex questions such as whether a system is behaving abnormally, how its behavior changes over time, what the usage and performance breakdown of an application is, and if there are seasonal patterns in how an application is used. By applying these formulas and functions, users can gain valuable insights into their infrastructure, applications, and business operations, and make data-driven decisions to optimize their systems and improve their end-user experience.
