Disable/enable appender for all loggers
Hello,
I am using three appenders in my log4net configuration (see bellow). But
I need programatically disable and reenable RollingFile appender at
certain situations. Is there any simple solution? I tried to use
programatic configuration only.
My config:
<log4net>
<appender name="Console"
type="log4net.Appender.ConsoleAppender">
<layout type="log4net.Layout.PatternLayout">
<!-- Pattern to output the caller's file
name and line number -->
<conversionPattern
value="%date{HH:mm:ss,fff} %5level [%thread] %message%n" />
</layout>
<Threshold value="DEBUG" />
</appender>
<appender name="RollingFile"
type="log4net.Appender.RollingFileAppender">
<appendToFile value="true" />
<file value="Service.log" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern
value="%date{dd-MM-yyyy HH:mm:ss,fff} %5level [%2thread] %message
(%logger{1}:%line)%n" />
</layout>
<rollingStyle value="Date" />
<Threshold value="DEBUG" />
</appender>
<appender name="EvLog"
type="log4net.Appender.EventLogAppender">
<ApplicationName value="IPserver" />
<layout type="log4net.Layout.PatternLayout">
<conversionPattern value="[%thread]
%message (%logger{1})" />
</layout>
<Threshold value="INFO" />
</appender>
<root>
<level value="DEBUG" />
<appender-ref ref="RollingFile" />
<appender-ref ref="Console" />
<appender-ref ref="EvLog" />
</root>
</log4net>
I tried to complete rewrite this config into C# code:
private readonly log4net.Appender.ConsoleAppender AppConsole;
private readonly log4net.Appender.RollingFileAppender AppFile;
private readonly log4net.Appender.EventLogAppender AppEvlog;
private log4net.Repository.Hierarchy.RootLogger rootLog;
//XmlConfigurator.Configure(new
System.IO.FileInfo(IPserverCore.IPserver.GetAppPath() +
"log4net.config"));
//xml configurator replaced by code
AppConsole = new log4net.Appender.ConsoleAppender();
AppConsole.Layout = new
log4net.Layout.PatternLayout("%date{HH:mm:ss,fff} %5level [%thread]
%message%n");
AppConsole.Threshold = log4net.Core.Level.Debug;
AppFile = new log4net.Appender.RollingFileAppender();
AppFile.AppendToFile = true;
AppFile.Layout = new log4net.Layout.PatternLayout("%date{dd-MM-yyyy
HH:mm:ss,fff} %5level [%2thread] %message (%logger{1}:%line)%n");
AppFile.File = "Service.log";
AppFile.RollingStyle =
log4net.Appender.RollingFileAppender.RollingMode.Date;
AppFile.Threshold = log4net.Core.Level.Debug;
AppEvlog = new log4net.Appender.EventLogAppender();
AppEvlog.Layout = new log4net.Layout.PatternLayout("[%thread] %message
(%logger{1})");
AppEvlog.ApplicationName = "IPserver";
AppEvlog.Threshold = log4net.Core.Level.Info;
rootLog = new
log4net.Repository.Hierarchy.RootLogger(log4net.Core.Level.Info);
rootLog.AddAppender(AppConsole);
rootLog.AddAppender(AppFile);
rootLog.AddAppender(AppEvlog);
//----
log = LogManager.GetLogger(typeof(IPservice));
Log.Info("Start"); // no log produced here...
rootLog.RemoveAppender(AppFile); // disable file logging
...
But after rewriting aplication doesn't create any logs....
Did I miss some settings or am I complete wrong?
Thanks for any suggestions

RE: Disable/enable appender for all loggers
Posted by "Vanderkolk, John" <Jo...@compuware.com>.
I would do something like this:
log4net.Appender.IAppender[] appenders =
log4net.LogManager.GetRepository().GetAppenders();
for (int i = 0; i < appenders.Length; ++i)
{
Log4net.Appender.FileAppender appender = appenders[i] as
log4net.Appender.FileAppender;
if (appender != null && appender.Name == "RollingFile")
appender.Threshold = log4net.Core.Level.Off;
}
Or if you want to turn all File Appenders you can take out the ' &&
appender.Name == "RollingFile"'.
