Key metrics for SQL Server monitoring

SQL Server is a relational database management system developed by Microsoft that uses Transact-SQL (T-SQL) as its query language. It offers various ways to optimize and configure resource use, such as storing tables in memory instead of on disk and controlling the distribution of CPU, memory, and storage through resource pools. To ensure optimal performance, it is essential to monitor key metrics related to SQL Server's functionality, including data persistence, query optimization, indexes, and resource pooling. This guide provides an overview of these metrics and their importance in maintaining a healthy and available SQL Server environment.
