问题
So I am starting this new project and want to use Log4net to log to the Database. I am using EF for other things and it connects fine. For some reason L4N is not logging anything but not throwing any errors. Just wondering what step(s) I may be missing, hope someone can point it out. Do I need to "save" to the db somehow? Thanx so much in advance.
My web.config:
<log4net>
<appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">
<bufferSize value="100" />
<connectionType value="System.Data.EntityClient.SqlConnection, System.Data, Version=1.0.3300.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" />
<connectionString value="data source=myserver;initial catalog=Reporting;integrated security=false;persist security info=True;User ID=myid;Password=mypassword" />
<commandText value="INSERT INTO [myschema].[Log] ([Date],[Thread],[Level],[Logger],[Message],[Exception]) VALUES (@log_date, @thread, @log_level, @logger, @message, @exception)" />
<parameter>
<parameterName value="@log_date" />
<dbType value="DateTime" />
<layout type="log4net.Layout.RawTimeStampLayout" />
</parameter>
<parameter>
<parameterName value="@thread" />
<dbType value="String" />
<size value="255" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%thread" />
</layout>
</parameter>
<parameter>
<parameterName value="@log_level" />
<dbType value="String" />
<size value="50" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%level" />
</layout>
</parameter>
<parameter>
<parameterName value="@logger" />
<dbType value="String" />
<size value="255" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%logger" />
</layout>
</parameter>
<parameter>
<parameterName value="@message" />
<dbType value="String" />
<size value="4000" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="%message" />
</layout>
</parameter>
<parameter>
<parameterName value="@exception" />
<dbType value="String" />
<size value="2000" />
<layout type="log4net.Layout.ExceptionLayout" />
</parameter>
</appender>
<root>
<level value="Info" />
<appender-ref ref="LogFileAppender" />
</root>
and my controller:
...
using log4net;
using System.Reflection;
namespace MyNames.Controllers
{
public class ClientController : Controller
{
ReportingEntities db = new ReportingEntities();
private readonly ILog log = LogManager.GetLogger(MethodBase.GetCurrentMethod().DeclaringType);
public ActionResult Index()
{
this.log.Debug("Sample message to log to Db");
return View();
}
}
}
EDIT: So I made the mods suggested gorilly but still doesnt work. Just happened to check output window and even though I enabled debugging it still shows this .
. Tried the debugging suggestion from here but no error was thrown.From my log4net internal debugging file:
log4net: Assembly [DotNetOpenAuth.Core, Version=4.1.0.0, Culture=neutral, PublicKeyToken=2780ccd10d57b246] Loaded From [C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files\root\bf082a83\4eb20e9a\assembly\dl3\c62a3103\e01aa9f6_fda1cf01\DotNetOpenAuth.Core.dll]

回答1:
Add this line to Global.asax.cs (in Application_Start()):
log4net.Config.XmlConfigurator.Configure();
Also, you can turn on log4net debugging to help you figure out what's going wrong by adding this line to your Web.config under <appSettings>
:
Edit: The below had value="false"
, but should be value="true"
.
<add key="log4net.Internal.Debug" value="true"/>
Edit:
You can send log4net's internal debug logging to a file by adding the following to your Web.config (see the official explanation here):
<system.diagnostics>
<trace autoflush="true">
<listeners>
<add
name="textWriterTraceListener"
type="System.Diagnostics.TextWriterTraceListener"
initializeData="C:\mylogdirectory\log4net_debug.txt" />
</listeners>
</trace>
</system.diagnostics>
