The Microsoft Dynamics™ AX Trace Parser is a user interface and data analyzer built on top of the Event Tracing for Windows (ETW) framework added to Microsoft Dynamics™ AX 4.0. The ETW framework allows an administrator to conduct tracing with an overhead of approximately 4%. This low overhead allows administrators to diagnose performance problems in live environments as opposed to development environments.
The Trace Parser is built on top of Microsoft SQL Server 2005. It enables rapid analysis of traces to find the longest running code, longest running SQL query, highest call count and other metrics useful in debugging a performance problem. In addition, it provides a call tree of the code that was executed, giving the developer insight into the code, and the power to quickly become familiar with the flow of an unfamiliar piece of code. It also provides the ability to jump from the searching feature to the call tree, so that the person analyzing the trace can determine how the problematic code was called.
