How to run an ASP.NET application with verbose debug messages of the ASP.NET runtime

Question

How do I configure an ASP.NET application to write verbose log messages of what ASP.NET engine itself is doing. What I get with

<trace enabled="true" 
       pageOutput="false"
       requestLimit="10000"
       writeToDiagnosticsTrace="true"/>

is just as much as

[2488] aspx.page: Begin PreInit
[2488] aspx.page: End PreInit
[2488] aspx.page: Begin Init
[2488] Unhandled Execution Error: -- Object reference not set to an instance of an object.: at ... ...
[2488] aspx.page: Begin PreInit
[2488] aspx.page: End PreInit
[2488] aspx.page: Begin Init
[2488] aspx.page: End Init
[2488] aspx.page: Begin InitComplete
[2488] aspx.page: End InitComplete
[2488] aspx.page: Begin PreLoad
[2488] aspx.page: End PreLoad
[2488] aspx.page: Begin Load
[2488] aspx.page: End Load
[2488] aspx.page: Begin LoadComplete
[2488] aspx.page: End LoadComplete
[2488] aspx.page: Begin PreRender
[2488] aspx.page: End PreRender
[2488] aspx.page: Begin PreRenderComplete
[2488] aspx.page: End PreRenderComplete
[2488] aspx.page: Begin SaveState
[2488] aspx.page: End SaveState
[2488] aspx.page: Begin SaveStateComplete
[2488] aspx.page: End SaveStateComplete
[2488] aspx.page: Begin Render
[2488] aspx.page: End Render

Is there a way to get more verbosity? What's about the verbosity level of application_folder/logs/ files?
