Correct answer & explanation
✓
Deadlocks
The 'Deadlocks' metric in Amazon RDS for SQL Server specifically counts the number of deadlocks that occur on the DB instance. Option A is incorrect because 'BlockedTransactions' tracks transactions that are blocked, not deadlocks. Option C is incorrect because 'DatabaseConnections' is a count of active connections, not related to deadlocks. Option D is incorrect because 'LockWaits' measures the number of lock waits, which is a different contention event.
