Hi,
I have tried to search for an answer here and tried to understand the
documentation but can't say I have been successful.
I'm using this configuration value for the layout pattern:
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date %newline [%thread] %newline %-5level :
%message %newline" />
</layout>
This is too much information. I don't want the stack trace, only
exception.messge and exception.InnerException.
How do I specify that in the layout?
Thanks in advance for helping.
Habib

I believe the place holder "%message" refers to the data sent when you do log.Debug(message). I think it's more about how you build the message in the logger that matter in your case. Try to send us your logger call maybe.

Yann,
Thanks for the reply.
I guess I could do
catch (Exception ex)
{
if (log.IsWarnEnabled)
log.Warn(string.Format("Error blah {0}:{1}\n{2}\n{3}", key1, key2,
ex.Message, ex.InnerException));
}
Instead, I would prefer to pass in the exception
log.Warn(string.Format("error blah {0}:{1}", key1,key2 ), ex);
I want to use an exception layout to selectively log parts of the exception.
I'll use a text file appender to log the stack trace and every gory detail
and use an SMTP appender to semd me just the exception message and
InnerException. And I can change what gets logged at any time.
I see from the SDK that there is an exception layout but I just cant figure
out what I need to do.
regards
Habib

Although you solved you problem by parsing the exception I'll give you an alternative to do such a job. You can implement a Renderer (a class which implements the interface IObjectRenderer) for your exception and put the information you want about the exception. Then, you just have to add a <renderer renderingClass="MyClass.MyRenderer" renderedClass="Exception" /> element to the config file. regards, Fred |
