New SQL Monitor Custom Metric: Untrusted Check Constraints

This metric returns the number of check constraints that have their is_not_trusted flag set to 1 in the sys.check_constraints table. Untrusted constraints force SQL Server to construct less efficient query plans, because it doesn’t know enough about the kind of data contained in the table. This can point to a data integrity issue which should be investigated.

The Disabled Index

I run this code on SQL Server 2022.

(
    drinkid INT NOT NULL
        CONSTRAINT DrinkPK PRIMARY KEY CLUSTERED,
    drinkname VARCHAR(20),
    rating NUMERIC(2, 1)
)
GO

INSERT INTO Drink
(
    drinkid,
    drinkname,
    rating
)
VALUES
