Execution Warnings Event Class

The Execution Warnings event class indicates memory grant warnings that occurred during the

execution of a SQL Server statement or stored procedure. This event class can be monitored to

determine if queries had to wait one second or more for memory before proceeding, or if the

initial attempt to get memory failed. Information about query wait periods can help uncover

contention issues in the system that can affect performance.
