log4net

问题 really simple question -> i can't seem to get any data from Log4Net in my ASP.NET application. I've got a simple ASP.NET website, which references a class library. In this class library, I have some lines that call the logger. I'm trying to read the log4net output data in my Visual Studio 2008 debugging Output window . Here's my code and my configuration... //Class Library project //File: Foo.cs public class FooService { private static readonly ILog log = LogManager.GetLogger(typeof

问题 TickZoom is a very high performance app which uses it's own parallelization library and multiple O/S threads for smooth utilization of multi-core computers. The app hits a bottleneck where users need to write information to a LogAppender from separate O/S threads. The FileAppender uses the MinimalLock feature so that each thread can lock and write to the file and then release it for the next thread to write. If MinimalLock gets disabled, log4net reports errors about the file being already

问题 I have been looking for a way to log class names and method names as part of my logging infrastructure. Obviously I'd like to make it simple to use and fast at runtime. I've done a lot of reading about logging class names and method names, but I've run across 2 themes. That log4net uses an internally throws exception to generate a stack frame and that gets expensive if you use that generally for all logging. Confusion. There is a lot of literature out there. I've tried a bunch of it and not

问题 Recently added log4net.dll to our data object. Our data object builds perfectly but when you try to build anything that references our data object you get the following error: No way to resolve conflict between "log4net, Version=1.2.10.0, Culture=neutral, PublicKeyToken=692fbea5521e1304" and "log4net, Version=1.2.9.0, Culture=neutral, PublicKeyToken=b32731d11ce58905".

问题 I like to add category prefix to all the messages on the existing logging messages. However it is tedious to add this prefix to all the existing logging messages one by one. Is there a way in I can just add an attribute to the class level then all the messages in this class will be logged for certain category? Instead of the way right now as below, Log.Info("[Ref] Level 1 Starts ..."); I really want to something like this or a different way to define the log4net.ILog. [LoggingCategory("Ref")]

问题 There seems to be some discussion on whether log4net is thread-safe, the consensus is that the framework is thread-safe, but appenders are not and need to be used correctly to achieve thread-safety. can someone shine some light on this and possibly give example of lets say RollingFileAppender used in a thread-safe way? does it need to be pushed into context? somehow locked, or what? 回答1: According to this link, RollingFileAppender is thread safe (as far as logging is concerned). This is

问题 I have an azure worker role which I have configured to use a log4net Trace Appender which writes to WindowsAzure.Diagnostics. This is done by making the following calls in the RoleEntryPoint of the worker role. using System; using Microsoft.WindowsAzure.Diagnostics; using log4net.Config; namespace XXX { public class WorkerRole : RoleEntryPoint { public override bool OnStart() { var config = DiagnosticMonitor.GetDefaultInitialConfiguration(); config.Logs.ScheduledTransferLogLevelFilter =

问题 I was just wondering why there isn't a trace level in log4Net. This level seems to be missing and I sometimes feel the need to use it, for example to output what events are being executed in an application. This feature is a part of log4J. I know I can create a custom level like is talked about here but I don't want to put time and effort in something I feel should be part of the library itself. Do you know about a log4net extension library that implements this or why this wasn't a part of
