Hi Wolfgang, sorry, but I havent really been paying much attention to this thread I am afraid. Is it not possible for you to write your log to a DB and then create logfiles from that? It seems a bit long-winded, but could be a solution as opposed to creating your own appender.

I can’t defer the logger configuration, because I need basic logging from the beginning. I could probably use a separate log file for each job, but that seems a bit awkward. I think I’ll stick to the “write my own appender” approach for the moment. Thx, Wolfgang From: Ross Hinkley [mailto:rosshink...@gmail.com] Sent: Freitag, 31.

Rather than deferring the log file getting created, couldn't you defer execution of the configurator? You could use a getter to run the configurator, like the following: private static ILog _log = LogManager.GetLogger(typeof(Program)); public static ILog log { get { if(!log4net.LogManager.GetRepository().Configured) log4net.Config.XmlConfigurator.Configure(new FileInfo(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile)); return _log; } } This way, your logger will only get configured (and the file subsequently made) if something is logged. Is it a hack? Absolutely. But it's the quickest way I could think of to answer your question. :) -Ross On Fri, Jul 31, 2009 at 10:23 AM, Wolfgang Trog <wolfg...@wollinet.com> wrote: For now, I tried a quick hack and modified FileAppender and it’s now working like I want: override public void ActivateOptions() { … if ( m_fileName != null ) { //SafeOpenFile( m_fileName, m_appendToFile ); } else { LogLog.Warn( "FileAppender: File option not set for appender [" + Name + "]." ); LogLog.Warn( "FileAppender: Are you using FileAppender instead of ConsoleAppender?" ); } } I would prefer a solution, where I don’t have to use my own appender, but at least I have a workaround.

But I don’t want a file, if the job is not executed. The jobs are only executed once a month for example. Thx for the quick response !

From: wolfg...@wollinet.com To: log4net-user@logging.apache.org Subject: Defer file creation Date: Fri, 31 Jul 2009 16:15:28 +0200 Hi Everbody, I’m looking for a way to defer the creation of the log file until the first entry is logged. I want to use log4net for writing protocols for jobs that can be executed in my application. With my current configuration the file is created during startup which makes no sense if the job doesn’t run. My current configuration: <appender name="…" type="log4net.Appender.RollingFileAppender"> <file value="....." /> <appendToFile value="false" /> <rollingStyle value="Date" /> <datePattern value="yyyy_MM_dd.\tx\t" /> <staticLogFileName value="false" /> <threshold value="INFO" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date;%level;%m%n" /> </layout> </appender> One possibility seems to be to generate the appender programmatically, but then I lose a lot of flexibility. Another one is writing my own appender (or subclassing an existing one). Is there another way ? Any help is appreciated, Wolfgang Share your memories online with anyone you want.
