DebugDiag is composed of two main modules: Collection and Analysis


Collection Module: 
============ 
The collection module is composed of three main components: The Debugging service, the debugger host and the user interface. It is the base install component of the tool.

  1. Debugging service: DbgSvc.exe. The Debugging Service performs the following tasks:  ...
  2. Debugger Host : DbgHost.exe. The Debugger Host hosts the Windows Symbolic Debugger Engine (dbgeng.dll) to attach to processes and generate memory dumps. Dbghost.exe has no dependency on the service “DbgSvc.exe” and can be used separately.

  2. Analysis UI: DebugDiag.Analysis.exe The analysis UI is a .NET 4.0 executable that allows you to runs selected "Analysis Rules" against one or more memory dumps. ...
  3. Rule Builder: DebugDiag.RuleBuilder.exe The Rule builder UI is a .net 4.0 Workflow application that allows you to create simple workflow analysis rules...
