Customize the exception output
Hi,
I've had a request from the developers at my company to modify the way in
which log4net outputs exceptions to the log. This would need to take effect
in my EventLogAppender and AdoNetAppender. Will I need to create my own
custom class similar to ExceptionLayout or a custom class similar to
ExceptionPatternConverter? How can I specify this change to the
EventLogAppender?
The request is to format the exception more like the way the .NET Enterprise
Library did in .NET 1.1.:
1) Exception Information
*********************************************
Exception Type: X.WebApps.NewsRoom.WebControls.NewsSystemException
Message: Could not retrieve a list of articles from the category
Data: System.Collections.ListDictionaryInternal
TargetSite: NULL
HelpLink: NULL
Source: NULL
2) Exception Information
*********************************************
Exception Type: System.Exception
Message: An error occurred while processing the required SQL script:
D:\WebSites\X\WebAppsFolders\WebAppsCommonFiles\\scripts\core.config
Data: System.Collections.ListDictionaryInternal
TargetSite: Void ExecuteScripts(System.String, System.String[], Boolean,
Boolean)
HelpLink: NULL
Source: X.WebApps.CoreLibrary.X.X
StackTrace Information
*********************************************

Boolean trapExceptions, Boolean sendAppPath)

at X.WebApps.CoreSystem..ctor(String application)
at
X.WebApps.NewsRoom.WebControls.NewsArticleDisplayer.GetNewsArticleAndCategory(Category&
newsCategory, Article& newsArticle)
Here is a sample of what is being output by the default format:
System.Exception: Testing application error handling from the
DevCenter/ApplicationErrorTest.aspx form. --->
System.ArrayTypeMismatchException: Oh my gosh some sort of array mismatch
occurred in this fake class! Error! Error!

Re: Customize the exception output

Hi Ron,
I noticed that the Exception Information part can really vary per exception,
so I don't know how well a pattern output will work. It would be nice to
understand what the Enterprise Library does to figure this stuff out. I may
have to reverse engineer the code with a tool to see. Yes, Ent Lib does
spit out "Void ExecuteScripts(System.String,System.String[], Boolean,
Boolean)."
Another variation (of many, apparently):
1) Exception Information
*********************************************
Exception Type: System.Security.SecurityException
Action: 0
PermissionType: NULL
FirstPermissionThatFailed: NULL
PermissionState: NULL
Demanded: NULL
GrantedSet: NULL
RefusedSet: NULL

PermitOnlySetInstance: NULL
FailedAssemblyInfo: NULL
Method: NULL
Zone: MyComputer
Url: NULL
Message: The current user has tried to access a secure area with an
unauthorized role.

TargetSite: Void AccessDenied(Boolean)
HelpLink: NULL

Re: Customize the exception output
Posted by Ron Grabowski <ro...@yahoo.com>.
My initial thought was this:
<layout type="log4net.Layout.PatternLayout">
<![CDATA[
%counter) Exception Information
*********************************************
Exception Type: %exception{type}
Message: %exception{message}
Data: ???
TargetSite: NULL
HelpLink: NULL
Source: NULL
]]>
</layout>
I don't think the current exception pattern implementation accepts
additional parameters.
I remember seeing a counter pattern somewhere but I can't seem to find
it now.
What should go in the "Data:" part of your example?
Does EntLib really show this text "Void ExecuteScripts(System.String,
System.String[], Boolean, Boolean)" or does it just show
"ExecuteScripts"?
I would create an ExtendedPatternLayout that registers additional
converters and have your appenders use that.
Create a JIRA issue if you think some of these patterns should be part
of PatternLayout.
