Over the course of this stairway series, we're going to explore in detail the use of Extended Events as a diagnostic data collection tool, to track down causes of poor performance in SQL Server. This first level will start from a point known and familiar to many DBAs, namely the use of SQL Trace to track down and investigate long-running queries.

In this Level, we'll walk through the basics of using the New Session dialog in the UI to create a new event session, define its events, actions and predicates, and establish a target for the session in which to collect the event data.

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.

Today we have a guest editorial from Erin Stellato that reminds us that we have had support from many, and it's important to thank them from time to time.

By capturing baseline data, a well-prepared DBA should get a good idea of what potential issues they will face. In this article Erin Stellato looks at Wait Statistics and what they can tell you about your databases.

It is widely acknowledged within the SQL Server community that baselines represent valuable information that DBAs should capture. Unfortunately, very few companies manage to log and report on this information, and DBAs are then forced to troubleshoot from the hip and scramble to find evidence to prove that the database is not the problem. This article will make a compelling argument for why DBAs must start capturing baseline information, and will create a roadmap for subsequent posts.

In this article, we'll tackle the topic of monitoring disk space usage. By tracking how much is in use and how much is still available, over time we'll have the data we need for better capacity planning, and can ensure that a database won't ever run out of disk space.
