What is ULS Logs?

ULS Logs (Unified Logging System Logs) are diagnostic logs used extensively in Microsoft SharePoint and other Microsoft server products. They capture a wide variety of events and data, providing insights into the health, performance, and operational activities of the system. Administrators and developers use ULS logs to troubleshoot issues, monitor system behavior, and analyze performance bottlenecks. The logs are typically stored in a binary format and can be viewed and analyzed using tools like the SharePoint ULS Viewer or PowerShell scripts.
