default trace, trace flags, performance counters, deadlock graphs, ring buffers, blocked process reports, DBCC commands, various logs, and others. So you may wonder why anyone would need a new event infrastructure such as Extended Events. It may sound shocking, but the diversity of the tools is the main reason. Having so many techniques available makes it difficult to maintain the code for each new release of SQL Server. That s from a developer s point of view. For the rest of us customers, consultants, users, and even for Microsoft support it s challenging to obtain relevant performance or troubleshooting information. Why Because the information needed usually comes from multiple sources. Furthermore, each of the tools available before SQL Server 2008 has its own strengths and weaknesses. Think about monitoring SQL Server using SQL Server Profiler: it s graphical, easy to use, and can be used in correlation with PerfMon logs, but the performance overhead can be pretty serious. Extended Events is the potential event infrastructure for the next releases of SQL Server. This is my personal opinion, and the role of this chapter is to support this opinion with facts.

It allows defining events to be monitored and provides a variety of ways to consume the events. It can be synchronous or asynchronous (events are fired synchronously). It can trigger actions when an event fires.

XEVENT: the next event infrastructure
It uses predicates to filter events from consumers. It has causality tracking (through inherited IDs). It has high performance and good scalability. The cost of firing a single event is extremely small (approximately 2 s CPU time on a 2 GHz processor). But keep in mind that when consuming the events, it s a different story depending on how the event is consumed, the overhead can become significant. ETW (Event Tracing for Windows) is enabled (integration of Extended Events and ETW is supported). It s controlled through T-SQL DDL statements (such as CREATE and ALTER). It exposes rich metadata through a complete set of catalog views, Dynamic Management Views, and functions. Listing 1 uses Extended Events to monitor long-running queries. We ll use the example to understand some of the concepts introduced by Extended Events.
Listing 1 Using Extended Events to monitor long-running queries
USE master; GO -- Create Event Session CREATE EVENT SESSION GetLongRunningQueries ON SERVER ADD EVENT sqlserver.sql_statement_completed( ACTION (sqlserver.sql_text) WHERE sqlserver.database_id=1 AND duration > 20000); GO -- Add Event Bucketing target -- source_type = {0|1}, 0 = event 1 = action ALTER EVENT SESSION GetLongRunningQueries ON SERVER ADD TARGET package0.synchronous_bucketizer (set filtering_event_name='sqlserver.sql_statement_completed', source_type=1, source='sqlserver.sql_text'); GO -- Start the Event Session ALTER EVENT SESSION GetLongRunningQueries ON SERVER STATE=START; GO -- For testing purpose we will create a stored procedure that will run -- longer than 20 seconds CREATE PROCEDURE usp_WaitForATime AS BEGIN DECLARE @D DATETIME=GETDATE(),@S VARCHAR(128); WHILE (DATEDIFF(ss,@D,GETDATE())<22) SET @S = @@VERSION; END; GO -- Execute the procedure 5 times -- This works in SQL Server Management Studio EXEC usp_WaitForATime; GO 5
