c# - Log4Net not writing to SQL Table -

can off 2nd set of eyes? missing something.

i'm using log4net in web api app. whenever invoke log.error() executes, nothing gets written dbo.log table. running local database. when replaced configuration 1 wrote file, code worked perfectly.

here configuration , code looks like.

the log4net.config file contains following:

<?xml version="1.0" encoding="utf-8" ?>  <configuration>    <configsections>      <section name="log4net" type="log4net.config.log4netconfigurationsectionhandler, log4net" />    </configsections>      <log4net>      <appender name="adonetappender" type="log4net.appender.adonetappender">        <buffersize value="100" />        <connectiontype value="system.data.sqlclient.sqlconnection, system.data, version=4.0.0.0, culture=neutral, publickeytoken=b77a5c561934e089" />        <connectionstring value="data source=mud-dad\sqlexpress;initial catalog=fitachiever;persist security info=true;user id=sa;password=asdadf334"/>        <commandtext value="insert dbo.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="debug"/>        <appender-ref ref="adonetappender"/>      </root>    </log4net>  </configuration>

the global.asax.cs file contains following, note call log4net.config() method specifies config use.

    public class webapiapplication : system.web.httpapplication {     private static readonly log4net.ilog log = log4net.logmanager.getlogger(typeof(webapiapplication));     protected void application_start()     {          log4net.config.xmlconfigurator.configure(new system.io.fileinfo(server.mappath("log4net.config")));          arearegistration.registerallareas();         globalconfiguration.configure(webapiconfig.register);         filterconfig.registerglobalfilters(globalfilters.filters);         routeconfig.registerroutes(routetable.routes);         bundleconfig.registerbundles(bundletable.bundles);     } } 

}

the initialization of logger in controller is:

   public class fitdashboardcontroller : apicontroller {     private static readonly ilog log = logmanager.getlogger(methodbase.getcurrentmethod().declaringtype);      ifitdashboardservice fitdashboardservice = new fitdashboardservice(); 

...

and call is:

            catch (system.exception ex)         {             log.error("error:" + methodbase.getcurrentmethod().name + " :: " + ex.message);          } 

again, code works when writing file, not database. ideas?

this question has been answered here. problem <buffersize> tag, according linked answer...

<buffersize value="100" /> 

it saying keep 100 logs in memory until written db. maybe that's why don't see in db?

change code <buffersize value="1" /> , should cause log4net write database after keeping 1 log in memory. see apache's documentation on buffersize more details.
