Subject RE: Disable/enable appender for all loggers
Date Fri, 03 Aug 2007 21:26:36 GMT
Thanks for proposal to John and Ron, it works well.
But when I tried the reverse strategy (set Threshold to OFF in config file and change to DEBUG
when needed), I noticed that empty log file (Service.log in my configuration) is created (file
size = 0 bytes).
Can this feature be disabled?
I think it would be great to add some samples of programatic configuration into SDK documentation
- current documentation is completely out of any example.

Instead of removing the appender you could just set its threshold to OFF then when you want
to enable it again you can set it back to DEBUG:

// untested
public static void SetThreshold(string appenderName, Level threshold)
    foreach (AppenderSkeleton appender in LogManager.GetRepository().GetAppenders())
        if (appender.Name == appenderName)
            appender.Threshold = threshold;

Subject: Disable/enable appender for all loggers

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: 


                <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" /> 


                        <Threshold value="DEBUG" /> 


                  <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" />


                        <rollingStyle value="Date" /> 

                        <Threshold value="DEBUG" /> 


                  <appender name="EvLog" type="log4net.Appender.EventLogAppender"> 

                        <ApplicationName value="IPserver" /> 

                        <layout type="log4net.Layout.PatternLayout"> 

                                <conversionPattern value="[%thread] %message (%logger{1})"


                        <Threshold value="INFO" /> 



                        <level value="DEBUG" /> 

                        <appender-ref ref="RollingFile" /> 

                        <appender-ref ref="Console" /> 

                        <appender-ref ref="EvLog" /> 



  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]

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); 






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
