The topic that I presented on was the SQL Server System Health Session which has been there since SQL Server 2008 and has been further enhanced in SQL Server 2008.
All the System Health Session articles that I have written are available in this summary post: http://troubleshootingsql.com/2012/09/24/system-health-session-and-beyond/ (The RDL files for the reports demoed can be downloaded from here)
System Health Session Custom Reports for management studio can be downloaded from here: http://troubleshootingsql.com/2011/09/28/system-health-session-part-4/ (Note that the custom SSMS reports only work for SQL Server 2008 and SQL Server 2008 R2 instances)
Presentation delivered at the meet is available above!
As usual it was good fun presenting at the session! And what I really like about such sessions is that I get to meet the #SQLFamily in person!!
