When you're monitoring SQL Server, it's better to capture a baseline for those aspects that you're checking, such as workload, Physical I/O or performance. Once you know what is normal, then performance tuning and resource provisioning can be done in a timely manner before any problems becomes apparent. We can prevent problems by being able to predict them. Louis shows how to get started.

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.
