Monitoring with Transact-SQL Statements

Microsoft® SQL Server™ provides several Transact-SQL statements and system stored procedures that allow ad hoc monitoring of a computer running SQL Server. Use these statements when you want to determine, at a glance, information about server performance and activity. The most common information monitored using Transact-SQL statements includes:

• Current locks.
• Current user activity.
• Last command batch submitted by a user.
• Data space used by a table or database.
• Space used by a transaction log.
• Oldest active transaction (including replicated transactions) in the database.
• Performance information relating to I/O, memory, and network throughput.
• Procedure cache usage.
• General statistics about SQL Server activity and usage, such as the amount of time the CPU has been performing SQL Server operations or the amount of time SQL Server has spent performing I/O operations.

Most of this information can also be monitored using either SQL Server Enterprise Manager, SQL-DMO, or Windows NT Performance Monitor.
