Definition - What does SQL Diagnostics mean?
SQL diagnostics is a solution that provides important information on the health and performance of SQL servers and queries such as memory usage, query speed and efficiency, and CPU usage. It is a popular solution deployed or integrated with different systems across the world. Enterprises can manage SQL diagnostics in different ways such as web-based consoles and command-line interfaces.
Techopedia explains SQL Diagnostics
SQL diagnostics can do a wide range of tasks, from monitoring performances of physical and virtual environments to helping optimize queries for better speed and efficiency with other tasks such as optimizing CPU and memory usage, database optimization and managing transactions between the server and the database.
SQL diagnostics are a platform-independent solution and can be used from almost all platforms. Users can manage the solution with the help of web-based consoles or command-line interfaces. In the web-based consoles, users can get a dashboard in which the performance and health parameters of different SQL servers and databases are provided in the form of analytics with additional options of drilling down on the data. Users can view alerts and performance metrics related to virtual machines and their hosts which can include CPU, memory, network and disk usage. Users can identify poorly performing SQL queries, statements, batches and stored procedures that can cause blocks and deadlocks and consume high CPU. Thresholds can be set and performance of SQL queries can be monitored on the basis of these thresholds.
