Inability to use EventLogAppender with ASPNET
With log4net internal debugging turned on, an attempt to create an
EventLogAppender for a web application is failing:
[3616] log4net: XmlHierarchyConfigurator: Setting Property [Layout] to
object [log4net.Layout.PatternLayout]
[3616] log4net: XmlHierarchyConfigurator: Setting Property [LogName] to
String value [Application]
[3616] log4net:ERROR XmlHierarchyConfigurator: Could not create Appender
[EventLog] of type [log4net.Appender.EventLogAppender]. Reported error
follows.

[3616] log4net: XmlHierarchyConfigurator: Hierarchy Threshold []
[3616] log4net: AppenderSkeleton: Finalizing appender named [EventLog].
The FAQ on the log4net site says that the ASPNET account has permission to
write to the event log if created already. Just to be sure, I made sure to
add ASPNET and IUSR_machinename to the Administrators group, but this does
not work either.
Here is my configuration:
<appender name="EventLog" type="log4net.Appender.EventLogAppender" >
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%date [%thread][%mdc{AspNetSessionID}] %-5level
%logger - %message%newline" />
</layout>
<logName value="Application"/>
</appender>
<root>
<level value="ALL" />
<appender-ref ref="LogFileAppender" />
<appender-ref ref="EventLog" />
</root>
Sorry if this is a silly newbie question, but I couldn't find much out there
on configuring/using EventLogAppender besides "its tough". Can anyone help?
Thanks,

What event source is used by default if no ApplicationName is supplied?

I agree, should be added to FAQ. There's a MS artcicle here:
http://support.microsoft.com/default.aspx?scid=kb;en-us;329291.
But you don't NEED to hack the registry. If it's a problem for you, just
remove the LogName and ApplicationName elements from your corn-fig file and
you should run out-of-the-box. It's been a little while, but I believe I ran
that way at first. Of course, you won't get to have that ApplicationName
element jam something nice that you want into the 'Source' field in the
EventLog, but if access to the registry is a problem, ...

Adding permission explicitly to the EventLog key (and all
subkeys) seems to have done the trick.
Maybe this should be added to the FAQ... :)

Re: Inability to use EventLogAppender with ASPNET
Posted by Hollywood <ho...@thzero.com>.
I've been running into this lately. One of the items is to make sure your
have permissions to the event log to write with.
Check the HKLM\System\CurrrentControlSet\EventLog and make sure whatever
user your process (if WinForms the logged on user or if ASP the
website/webservices' AppPool user) has write permissions to it.
My appender looks like the following (although the appender config is from a
slightly older version of log4net):
<appender name="EventLogAppender" type="log4net.Appender.EventLogAppender">
<param name="LogName" value="Application"/>
<param name="ApplicationName" value="AppName"/>
<layout type="log4net.Layout.PatternLayout,log4net">
<param name="Header" value="[Log Header]\r\n"/>
<param name="Footer" value="[Log Footer]\r\n"/>
<param name="ConversionPattern" value="%c%n[%-5p] %d{ISO8601} .%m%n %x"/>
</layout>
<filter type="log4net.Filter.LevelRangeFilter">
<levelMin value="ERROR" />
<levelMax value="FATAL" />
</filter>
</appender>

I think what you're doing there is naming a custom EventLog with the same
name as the existing Application log, which in turn requires write access to
the registry. Just remove that line and see what happens.

Try removing your line:
<logName value="Application"/>
I think what you're doing there is naming a custom EventLog with the same
name as the existing Application log, which in turn requires write access to
the registry. Just remove that line and see what happens.
