In many support cases, our customers want to monitor the available space for the transaction log space for their database or to know what caused an error when the transaction is full.
Unfortunately, there is not supported to use DBCC SQLPERF(LOGSPACE) nowdays. For this reason, I would like to share with you another view where you could find out these results.
Running the below query you could find all transactions active, the users that are executing them , TSQL statement, etc..
SELECT TranSession.[session_id],SessionS.[login_name] AS [Login Name], TranDB.[database_transaction_begin_time] AS [Start_Time],
CASE TranActive.transaction_type
WHEN 1 THEN‘Read/write transaction’
WHEN 2 THEN‘Read-only transaction’
WHEN 3 THEN‘System transaction’
ENDAS [Transaction_Type],
CASE TranActive.transaction_state
WHEN 1 THEN‘The transaction has not been initialized’
WHEN 2 THEN‘The transaction is active’
WHEN 3 THEN‘The transaction has ended. This is used for read-only transactions’
WHEN 5 THEN‘The transaction is in a prepared state and waiting resolution.’
WHEN 6 THEN‘The transaction has been committed’
WHEN 7 THEN‘The transaction is being rolled back’
WHEN 8 THEN‘The transaction has been rolled back’
ENDAS [Transaction_State],
TranDB.[database_transaction_log_record_count] AS [Log_Records],
TranDB.[database_transaction_log_bytes_used] AS [Log_Bytes_Used],
SQlText.AS [Last_Transaction_Text],
