Trying to set up an EXTREMELY SIMPLE event log feature... and failing terribly! Please help a newbie
Hi and thanks in advance for the help.
I'm tearing my hair out over here trying to get this to work: a siple logger
that writes to the application section of the event log.
This is using log4net 1.2.10.0
Here is the app config:
--
?xml version=1.0 encoding=utf-8 ?
configuration
configSections
section name=log4net
type=log4net.Config.Log4NetConfigurationSectionHandler, log4net /
/configSections
log4net
appender name=EventLogAppender
type=log4net.Appender.EventLogAppender
layout type=log4net.Layout.PatternLayout
conversionPattern value=%date [%thread] %-5level %logger
[%property{NDC}] - %message%newline /
/layout
/appender
root
level value=ALL /
appender-ref ref=EventLogAppender /
/root
/log4net
/configuration
here is my code:
log4net.Config.XmlConfigurator.Configure();
logger = LogManager.GetLogger(EventLogAppender);
logger.Error(test);
---
No errors, nothing happens! I notice that there are no appenders.
nothing is written to the event log.
I am tearing my hair out trying to figure out what is going on, can somebody
help?

Try using System.Configuration.IgnoreSectionHandler as the type for the
configuration section handler.

This IS a console application, .net 3.5, and the app.config file is set to
always copy on build, so that rules out number one.
I ran the code you suggested, and yielded this information:
---
Root Information:
Name: log4net-default-repository Threshold: ALL
Root Appenders: EventLogAppender,
Hierarchy Appenders:
Appender: EventLogAppender Type: log4net.Appender.EventLogAppender
Loggers:
EventLogAppender Additivity: True Level: null
--
Does anything in there jump out at you, such as the Level perhaps?

The first is that if you are getting errors, you won't be able to see
them unless you are running from a console application (or unless you
set up a trace appender to grab the errors, I haven't done that so
you'll have to google for it). This will tell you if the problem is
with the error logging itself.
The second is a method which will tell you how your log4net is
configured. It's written in C#, so you may need to translate. This
should tell you if it is your log4net configuration process which is
going astray.
public static string GetHierarchyInformation() {
Hierarchy hier = (Hierarchy)LogManager.GetRepository();
StringBuilder sb = new StringBuilder();
// first, look for it in the root
sb.AppendLine(Root Information:);
sb.Append( Name: + hier.Name);
sb.AppendLine( Threshold: + hier.Threshold.ToString());
sb.Append( Root Appenders: );
foreach (IAppender a in hier.Root.Appenders) {
sb.Append(a.Name + , );
}
sb.AppendLine();
sb.AppendLine(Hierarchy Appenders:);

I tried your code, as originally posted, locally and it works with the addition
of the declaration of the logger variable (ILog logger;). The message should
output to the Application log. Couple of questions:
Are you expecting it to create and log to a EventLogAppender log?
Have you tried running this locally and checking your local event log?
If no, have you validated that security is correctly set/configured to allow
you to write to the event log of the remote machine?

The first thing I would is to make sure log4net itself is working. Your config
file runs correctly when I add a ConsoleAppender:
?xml version=1.0 encoding=utf-8 ?
configuration
configSections
section name=log4net
type=log4net.Config.Log4NetConfigurationSectionHandler, log4net /
/configSections
log4net
appender name=EventLogAppender type=log4net.Appender.EventLogAppender
layout type=log4net.Layout.SimpleLayout /

appender name=ConsoleAppender type=log4net.Appender.ConsoleAppender
layout type=log4net.Layout.SimpleLayout /
/appender
root
level value=ALL /
appender-ref ref=EventLogAppender /
appender-ref ref=ConsoleAppender /
/root
/log4net
/configuration
I can also see the entries in the Event Log. Internal debugging:
appSettings
add key=log4net.Internal.Debug value=true /
/appSettings
didn't show any problems. Do you get an exceptions when internal debugging is
turned on? From what I can tell it looks like there's something wrong with the
machine its running on.

Re: Trying to set up an EXTREMELY SIMPLE event log feature... and failing terribly! Please help a newbie
By golly, you got it!!!
By changing my layout to log4net.Layout.SimpleLayout, it started working!
The problem was with the layout format:
--
%date [%thread] %-5level %logger [%property{NDC}] - %message%newline
--
something in there caused the logger to fail. What is annoying is how
silently it failed, I wish there was an option to make log4net throw
verbose, easy-to-understand exceptions!
I got the layout string from various examples on the google. Go figure
someone posted code that fails...
