How is SQL performance measured?
SQL Server Execution Times: CPU time = 422 ms, elapsed time = 2296 ms. You can see we now have a fairly accurate measure of how long that query took to run (and how long to parse and compile). The CPU time is how much CPU is used, the elapsed time is how much time the query took overall.
What are SQL metrics?
Summary. There is a multitude of database metrics that we can collect and use to help us understand database and server resource consumption, as well as overall usage. This data can include hardware statistics, such as measures of CPU or memory consumed over time.
When to review the performance of stored procedures?
When reviewing performance of stored procedures, one must inspect the metrics for the underlying statements. The queries listed above should give a starting point for identifying problem areas within a specific stored procedure execution as well as identifying top consuming stored procedures over time.
How is SQL Server used to measure performance?
As SQL Server compiles your batches, it optimizes them, measuring statistics like the number of rows involved and adjusting the execution plan in response. In a sense, a “query” in SQL Server is a batch of one or more T-SQL statements compiled and run as an execution plan.
When to use KPI query in stored procedure?
Stored Procedure KPI Query: An additional query which may be useful when troubleshooting queries – this one parses out the parameters passed to the stored procedure so you can compare the parameters between executions. When reviewing performance of stored procedures, one must inspect the metrics for the underlying statements.
How to check the performance of the query store?
Query Store does not collect data for natively compiled stored procedures by default. Use sys.sp_xtp_control_query_exec_stats to enable data collection for natively compiled stored procedures. Wait stats are another source of information that helps to troubleshoot performance in the Database Engine.
