DBCC SQLPERF is a database console command (DBCC) in Microsoft SQL Server that can be used to display statistical information about various performance-related aspects of the database engine, such as the number of transactions, the number of locks, and the amount of memory being used. Displaying this statistical information can be useful for troubleshooting performance issues or for monitoring the overall performance of the database engine.
To use DBCC SQLPERF, you can specify one or more options to control which performance-related statistics are displayed. The options available are:
* LOGSPACE: displays information about the transaction log space usage.
* LATCH_WAIT: displays information about latch wait statistics.
* LOCK_WAIT: displays information about lock wait statistics.
* STATISTICS IO: displays information about input/output (I/O) statistics.
* STATISTICS TIME: displays information about query execution time statistics.
Here is an example of how to use DBCC SQLPERF to display information about transaction log space usage:
-- Display information about transaction log space usage
DBCC SQLPERF ('LOGSPACE');
The output of DBCC SQLPERF will be a list of performance-related statistics, depending on the options specified.
It’s important to note that DBCC SQLPERF is a read-only command and does not allow you to modify any of the performance-related statistics it displays.
