Log4Net - log file per user logged in.

Hi,

We use Log4Net for all of our logging and we have an issue in WiseJ and I’m thinking it could be to do with threads. When a user logs into our application, we setup a log file for them with their username in the filename. We then use Logging.Info / Error to log to that file. The issue we have is that log messages are going to the wrong files a lot.

We either need to resolve this or change the logging tool we use (would love to hear what other people use). Here’s our Logging class:

public class Logging
{
    private static readonly ILog log = LogManager.GetLogger(typeof(Logging));

    public static void Setup(string userName)
    {
        Hierarchy hierarchy = (Hierarchy)LogManager.GetRepository();

        hierarchy.Root.RemoveAllAppenders();

        PatternLayout patternLayout = new PatternLayout();
        patternLayout.ConversionPattern = "%date{dd-MMM-yyyy HH:mm:ss.fff} %-5level - %message%newline";
        patternLayout.ActivateOptions();

        FileAppender fileAppend = new FileAppender();
        fileAppend.AppendToFile = true;
        fileAppend.File = $"LogFile-{userName}.log";
        fileAppend.Layout = patternLayout;
        fileAppend.ActivateOptions();
        hierarchy.Root.AddAppender(fileAppend);

        ConsoleAppender consAppender = new ConsoleAppender();
        consAppender.Layout = patternLayout;
        consAppender.ActivateOptions();
        hierarchy.Root.AddAppender(consAppender);

        hierarchy.Root.Level = Level.Info;
        hierarchy.Configured = true;
    }

    public static void Info(string infoMessage)
    {
        log.Info(infoMessage);
    }

    public static void Error(string errorMessage)
    {
        log.Error(errorMessage);
    }

    public static void Error(string errorMessage, Exception ex)
    {
        log.Error(errorMessage, ex);
    }
}
