SQL Server provides a range of tools for monitoring its performance and health, including built-in features such as T-SQL queries, SQL Server Management Studio (SSMS), Performance Monitor, and system stored procedures. These tools enable real-time insights into database infrastructure, including metrics on CPU utilization, memory usage, disk I/O, and query performance. By using these tools, developers can identify bottlenecks in their applications, optimize query performance, and ensure the overall health of their SQL Server instance.
