If your log restores aren't happening when they’re meant to, you want to know about it. You’ll be relying on restoring from logs should anything happen to your databases, and if you can’t restore to a certain point in time, you risk losing valuable data.

During a transaction, data is written to the log cache so that it’s ready to be written to the log file on commit, or can be rolled back if necessary. When the log cache is being flushed to disk, the SQL Server session will wait on the WriteLog wait type. If this happens all the time, it may suggest disk bottlenecks where the transaction log is stored.

This metric measures the amount of memory used by the total number of ad hoc queries in the plan cache that have only run one time. This value is only accurate for the instant the query is run, and the value can change radically from one capture time to the next.

This metric is useful if you want to know exactly how much physical space a particular table is taking up, including the size of its indexes. If a database is growing quickly within a short time and you suspect a certain table is responsible, you can monitor its actual size, or the rate at which it is increasing.

If you manage a server where you are not in complete control of the creation of databases, or you’re unfamiliar with what settings to change, you may miss things out or set them incorrectly. This metric could pick up on issues that affect performance in obscure ways, and saves you having to search for them when a system suddenly stops performing as you would expect.

Using a default account for SQL Server services can be a security risk for two reasons. Firstly, it can give the service a higher level of permissions than it needs. Secondly, isolation is compromised by several services running under the same account. This metric checks whether SQL Server services are running under any of the default accounts, such as localsystem.

I have some data in a table:
CREATE TABLE #test_data
(
id INT PRIMARY KEY,
name VARCHAR(100),
birth_date DATE
);
-- Step 2: Insert rows
INSERT INTO #test_data
VALUES
(1, 'Olivia', '2025-01-05'),
(2, 'Emma', '2025-03-02'),
(3, 'Liam', '2025-11-15'),
(4, 'Noah', '2025-12-22');
If I run this query, how many rows are returned?
SELECT *
FROM OPENJSON(
(
SELECT t.* FROM #test_data AS t FOR JSON PATH
)
) t; See possible answers
