Log4net to write multiple files in each and every process when we trigger the events RRS feed

  • Question

  • We have added log4net.config file in our project;
        <level value="ALL" />
        <appender-ref ref="file" />
      <appender name="ErrorLog" type="log4net.Appender.RollingFileAppender">
        <file type="log4net.Util.PatternString" value="%property{LogFileName}" />
        <staticLogFileName value="false" />
        <appendToFile value="true" />
        <rollingStyle value="Date" />
        <preserveLogFileNameExtension value="true" />
        <maxSizeRollBackups value="-1" />
        <datePattern value="yyyy-MM-dd_HH-mm-ss'.txt'" />
        <lockingModel type="log4net.Appender.FileAppender+MinimalLock" />
        <layout type="log4net.Layout.PatternLayout">
          <conversionPattern value="%m%n" />
        <filter type="log4net.Filter.PropertyFilter">
          <filter type="log4net.Filter.LevelRangeFilter">
            <levelMin value="DEBUG" />
            <levelMax value="ERROR" />
      <logger name="ErrorLog">
        <maximumFileSize value="15MB" />
        <appender-ref ref="ErrorLog" />

    we need to log all the messages in every second when we trigger the events but problem is that a new log file created after each and every minute but instead that we need to generate new log file whenever we manually click on a particular button. Any help would be appreciated.

  • Hi Pooja,

    I do not exactly remember right now as I am currently not on my dev machine. But what I remember we did something like the following write a log when the function and track the function entering and exiting steps.below is the pseudo code. In this way every time get record in log4net when the functions get call., even you can record the function parameter what is passing into the function.

    public string abc(string v1, string v2)
       string.Format("{0} {1}", "Entering Function.", Log.Debug())
    //some code
       string.Format("{0} {1}", "Exiting Function.", Log.Debug())
