Log4net not logging any errors - log4net

Question

Ive added a log4net implementation to my project but it isnt logging anything at all
In my web.config
<log4net>
<appender name="FileAppender" type="log4net.Appender.SitecoreLogFileAppender, Sitecore.Logging">
<file value="C:\\inetpub\\wwwroot\\Onboarding\\data\\logs\\log.{date}.txt" />
<appendToFile value="true" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%4t %d{ABSOLUTE} %-5p %m%n" />
</layout>
<encoding value="utf-8" />
<filter type="log4net.Filter.LevelRangeFilter">
<param name="LevelMin" value="DEBUG" />
<param name="LevelMax" value="FATAL" />
</filter>
</appender>
</log4net>
In my global.asax:
void Application_Start(object sender, EventArgs e)
{
log4net.Config.XmlConfigurator.Configure();
}
In the class (at the class level) where I log the error
ILog log = LogManager.GetLogger(System.Reflection.MethodBase
.GetCurrentMethod().DeclaringType);
and then in the method itself:
_logger.Log(AusSuperOnboarding.Business.Logging.Enum.Level.Fatal,
GetType().Name, "Exception thrown in SendMessage()", null);

Answer 1

Makes sure the service account user that the web site code runs with has a write access to the path: C:\inetpub\wwwroot\Onboarding\data\logs
If you are using IIS web site, you can check the application pool associated with the site and then right click on the app pool and choose advanced settings, you can see the app pool identity in the Identity field.
View the properties of the log folder, Choose Security tab, click Edit and add the app pool identity user and make sure the "Modify" check box is ticked

Answer 2

Your configuration is incomplete.
You have defined appenders, but no loggers to use them. This means when you create a logger, it has no appenders associated with it, and thus no logging is done.
Add a root element to your config: as log4net loggers are hierarchical, any loggers you create will all inherit the appenders from it:
<root>
<level value="ALL" />
<appender-ref ref="FileAppender" />
<root>
