My log4net configuration is this,
<?xml version="1.0" encoding="utf-8" ?>
<log4netConfiguration>
<configSections>
<section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
</configSections>
<appSettings>
<add key="log4net.Config" value="log4net.config" />
</appSettings>
<log4net>
<appender name="RollingFileAppender" type="log4net.Appender.RollingFileAppender">
<file type="log4net.Util.PatternString" value="C:\my_logs/my_web_logs/my_log_%date{ddMMyyyy}.log" />
<appendToFile value="true" />
<rollingStyle value="Size" />
<maxSizeRollBackups value="5" />
<maximumFileSize value="30MB" />
<datePattern value="yyyyMMdd" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%4t %d{ABSOLUTE} %-5p %m%n"/>
<!--<conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] – %message%newline" />-->
</layout>
</appender>
<root>
<level value="INFO" />
<appender-ref ref="RollingFileAppender" />
</root>
</log4net>
</log4netConfiguration>
I have a Logger helper class as,
public static class Logger
{
private static readonly log4net.ILog log = log4net.LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
public static log4net.ILog Log
{
get { return log; }
}
}
In my assembly info, I have this entry,
// Configure log4net using the .config file
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]
log4net.config is the config file added to the web project.
In the code I log using the logger class,
Logger.Log.Info("User visits Sign In Page.");
Logging has been working when I set up the above setting. But suddenly logging has stopped working. But when I created a new asp.net mvc website with above settings, logging works for that. I tried with IIS Express and Local IIS. In both cases logging works for the test application I have created.
I cannot figure out why it's not logging? How can I diagnose this? What are the possible issues?
Solved by myself, reason was "for some reason" log4net configuration was not loaded from assembly info. Still I do not know why that happens.
I tried so many fixes proposed by different posts. Finally fixed the issue. Solution mentioned in this post helped me to solve the issue.
I have added following configuration,
<!--These settings load the log4net configuration.-->
<add key="log4net.Config" value="log4net.config"/>
<add key="log4net.Config.Watch" value="True"/>
It starts logging!
Then I removed following line from assembly info,
// Configure log4net using the .config file
[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", Watch = true)]
