Stairway to SQL Server Extended Events Level 4: Extended Events Engine - Essential Concepts

In this level, we're going to dig a little deeper into the Extended Events engine, its architecture, and fundamental components. It will give you a deeper understanding of why, in general, an Extended Events session is inherently lower in overhead than an equivalent SQL Trace. We'll also investigate how to design our event sessions to minimize any unnecessary overhead during event data collection, even when we need to create relatively complex event sessions to investigate difficult performance problems.  Read more...

Use Extended Events to Get More Information About failed SQL Server Login Attempts

You may have cases where an ancient application is using an old login or the wrong password. SQL Server is great about auditing failed logins and recording that they happened; it is not so great, however, at providing enough information to locate them. Aaron Bertrand offers some help.  Read more...

Optimizing tempdb configuration with SQL Server 2012 Extended Events

One of the most obvious bottlenecks in the performance of tempdb is caused by PAGELATCH, in-memory latch contention on the allocation bitmap of each data file used. We can use one of the rules-of-thumb to choose what should be roughly the best number of files, but how then do you check to see whether you've got it right for your data and workload?  Read more...

Using Extended Events to troubleshoot SQL Server issues

As a DBA, you'll encounter elusive performance, connectivity and locking problems that you'll need to troubleshoot. There are many tools that you can use such as Profiler. In addition to these tools, SQL Server 2008 offers extended events ("XEvents"), which you can use as a powerful tracing system. By default, the "system_health" extended events session is always on, and can provide you help to locate the source of trouble much faster.  Read more...
