PreCon Performance Analysis & Tuning Techniques at SQLSaturday in Istanbul

What a year: after as many as 3 SQLSaturdays (Denmark, Netherlands, Germany) behind me, I will now also speak at SQSaturday #258 in Istanbul, Turkey. And after my first PreCon this year at the SQLSaturday in Germany, which I was co-presenting together with Mladen Prajdić, on the part “XEvents”, I will now be giving a […]

Performance overhead of tracing with Extended Event targets vs SQL Trace under CPU Load

Inspired by the Blog Post “Measuring Observer Overhead of SQL Trace vs. Extended Events” by Jonathan Kehayias, I was curious to do some more benchmarking. I have already presented the results in my SQL Server Master-Class workshops on XEvents as well as at the PreCon of the SQLSaturday #230. Now I am finally sharing them […]

Survey: Which Tracing and Analysis-Tools do you use for SQL Server?

In my session Session „Hasta la vista Profiler – Tracing with Extended Events“, which I have presented at several occasions, I used to ask the audience which tools they used for monitoring so far.

A student in my recent SQL Server Master-Class workshop on extended events came up with the question for how much (more) space he would have […]

Tracing Analysis Services (SSAS) with Extended Events – Yes it works and this is how

One of the features new in Analysis Services 2012 is the support of the SQL Server Extended Events Framework. While there is no GUI support for that, yet, it is however possible to set up a XEvent session via DDL commands – just like it was in the “old days” with SQL Server 2008/ 2008 […]

SQL Server Master-Class Seminars – For all those who want to know exactly what’s what – Starting in May with Extended Events

My First Blog Post here is partly for my own cause, but on the other hand, it is for You and all those who are inquisitive and eager to learn in terms of SQL Server: I have often been asked if I wouldn’t want to write a book sometime to share my knowledge, or to […]

Locking & READONLY Filegroups vs READONLY Databases

The Topic Locking and Read-Only for filegroups and databases is one of the ongoing myths around SQL Server in forums – and at least half of the information unfortunately wrong. Since I recently fell into the trap myself, I want to write down, how it really is. To have a definite picture, I made 3 […]
