We just use this: <param name=”File” value=”${ALLUSERSPROFILE}/Company/Product/Logs/error.log”/> It works great. This line can simply be inserted into your current appender configuration: <appender name=”RollingFileAppender” type=”log4net.Appender.RollingFileAppender”> <param name=”File” value=”${ALLUSERSPROFILE}/Company/Product/Logs/error.log”/> </appender>
You could write a converter like this: public sealed class HexPatternConverter : PatternLayoutConverter { override protected void Convert(TextWriter writer, LoggingEvent loggingEvent) { long id; if (long.TryParse(loggingEvent.ThreadName, out id)) { writer.Write(id.ToString(“X”)); } else { writer.Write(loggingEvent.ThreadName); } } } then you configure the layout like this: <layout type=”log4net.Layout.PatternLayout”> <conversionPattern value=”[%hex_thread] %message%newline” /> <converter> <name value=”hex_thread” /> <type … Read more
I think I have worked out the issue. The steps follow: Create an an individual ILoggerRepository object (loggerRepository in this example) on each thread. Set the ThreadContexts property for the log file name. Use the XmlConfiguratior to configure the repository. Use the LogManager to Get the named logger (in the XML configuration file) using the … Read more
Essentially you create an interface and then a concrete implementation of that interface that wraps the classes and methods of Log4net directly. Additional logging systems can be wrapped by creating more concrete classes which wrap other classes and methods of those systems. Finally use a factory to create instances of your wrappers based on a … Read more
Sure, use a filter. Here’s the snippet posted on the blog, for future reference – all credit to the author of that blog post: <filter type=”log4net.Filter.LoggerMatchFilter”> <!– allows this sub-namespace to be logged… –> <loggerToMatch value=”Noisy.Namespace.But.Important” /> </filter> <filter type=”log4net.Filter.LoggerMatchFilter”> <!– …but not the rest of it –> <loggerToMatch value=”Noisy.Namespace” /> <acceptOnMatch value=”false” /> </filter>
According to Rune’s suggestion I implemented a basic TraceListener which output to log4net: public class Log4netTraceListener : System.Diagnostics.TraceListener { private readonly log4net.ILog _log; public Log4netTraceListener() { _log = log4net.LogManager.GetLogger(“System.Diagnostics.Redirection”); } public Log4netTraceListener(log4net.ILog log) { _log = log; } public override void Write(string message) { if (_log != null) { _log.Debug(message); } } public override void … Read more
I always use the code below to configure log4net from code. Works great! Hierarchy hierarchy = (Hierarchy)LogManager.GetRepository(); hierarchy.Root.RemoveAllAppenders(); /*Remove any other appenders*/ FileAppender fileAppender = new FileAppender(); fileAppender.AppendToFile = true; fileAppender.LockingModel = new FileAppender.MinimalLock(); fileAppender.File = Server.MapPath(“https://stackoverflow.com/”) + “log.txt”; PatternLayout pl = new PatternLayout(); pl.ConversionPattern = “%d [%2%t] %-5p [%-10c] %m%n%n”; pl.ActivateOptions(); fileAppender.Layout = pl; … Read more
Use this: void Error(object message,Exception t) Reason is in log4net documentation for void Error(object message): WARNING Note that passing an Exception to this method will print the name of the Exception but no stack trace. To print a stack trace use the void Error(object,Exception) form instead. Error(object message, Exception t) is the most flexible way … Read more
In my opinion the solution Ninject created is much nicer than the propertyinjection in Autofac. Therefore I created a a custom attribute which is a postsharp aspect which automatically injects my classes: [AutofacResolve] public IStorageManager StorageManager { get; set; } My aspect: [Serializable] [AttributeUsage(AttributeTargets.Property, AllowMultiple = false)] public class AutofacResolveAttribute : LocationInterceptionAspect { public override … Read more
You can use the pre-populated property log4net:HostName, for example: <conversionPattern value=”%property{log4net:HostName}” /> This way you don’t need to populate the MDC.
