Profiler comes with eight predefined templates for the Database Engine, plus the blank template. At first glance, you may or may not be able to guess what some of these templates are designed to capture. To be honest, until I played with each template, I couldn't figure out what each one was really designed to do, as the template names are not obvious. To learn how to use predefined templates, we don't have to take an in-depth look at each one. What I want to do is to talk about the first two templates in some detail, so you fully understand the concepts behind templates.
In other words, traces become very difficult to read if you collect too much data. You may get so overwhelmed that you become discouraged from wanting to learn how to master Profiler. For example, who would want to wade through several thousand Lock events (see Figure 3-1)? Returning too much data can put a performance hit not only on the SQL Server instance you are tracing, but on the local computer you are using to perform the trace. If, for some reason, you do need to collect a large number of events in a single trace, at least limit the length of the trace to a short period, say five minutes or less.
So, if you think about it for a moment, every trace you create, apart form the very simplest, should be a custom trace template! In this section we will be taking a look at the following topics: • • • • • • How to create a Trace Template from scratch How to create a Trace Template from a running trace How to create a Trace Template from a saved trace file or trace table How to modify a Trace Template How to execute a Trace Template How to import and export Trace Templates CREATING A CUSTOM TRACE TEMPLATE FROM SCRATCH Creating a trace template is as easy as creating a custom trace, although you use different Profiler options.
