log4net different appenders insert different tables - log4net

Question

I have 2 appender in my config file which is configured to insert to different tables, "Log" and "LogFirms", but somehow both of the loggers are inserting to both of the tables.
<log4net debug="true">
<appender name="AdoNetAppender" type="log4net.Appender.AdoNetAppender">
<bufferSize value="1" />
<commandText value="INSERT INTO Log ([Date],[Thread],[Level],[Logger],[Message],[Exception],[ClientIp],[Username],[Controller],[Action],[Parameters]) VALUES (#log_date, #thread, #log_level, #logger, #message, #exception, #clientip, #username, #controller, #action, #parameters)" />
...
</appender>
<appender name="AdoNetAppenderForFirms" type="log4net.Appender.AdoNetAppender" additivity="false">
<bufferSize value="1" />
<commandText value="INSERT INTO LogFirms ([Date],[Thread],[Level],[Logger],[Message],[Exception],[ClientIp],[Username],[Controller],[Action],[Parameters]) VALUES (#log_date, #thread, #log_level, #logger, #message, #exception, #clientip, #username, #controller, #action, #parameters)" />
...
</appender>
<root>
<level value="ALL" />
<appender-ref ref="AdoNetAppender" />
<appender-ref ref="AdoNetAppenderForFirms" />
</root>
</log4net>
Here is the logger class;
public static class Logger
{
private static ILog log { get; set; }
private static ILog logFirms { get; set; }
static Logger()
{
log = LogManager.GetLogger("AdoNetAppender");
logFirms = LogManager.GetLogger("AdoNetAppenderForFirms");
}
public static void Error(string controller, string action, string parameters, object msg, Exception ex)
{
if (controller == "AccountController" && logFirms.IsErrorEnabled)
{
logFirms.Error(msg, ex);
}
else if (log.IsErrorEnabled)
{
log.Error(msg, ex);
}
}
There is no error seen in the controller, so the problem must be in the configuration... I searched and tried adding
additivity="false"
property to the "AdoNetAppenderForFirms" element but that changed nothing. So do you have any advice to fix this?

Answer 1

You can do this by adding loggers to your configuration, instead of appenders on root level:
<root>
<level value="ALL" />
</root>
<logger name="AdoNetAppender" additivity="false">
<level value="ALL" />
<appender-ref ref="AdoNetAppender" />
</logger>
<logger name="AdoNetAppenderForFirms" additivity="false">
<level value="ALL" />
<appender-ref ref="AdoNetAppenderForFirms" />
</logger>
