log4net

问题 By default, log4net is a synchronous logging mechanism, and I was wondering if there was a way to have asynchronous logging with log4net? 回答1: If you go to the log4net website, you can find some examples, at least one of which is an asynchronous Appender. http://logging.apache.org/log4net/release/example-apps.html Note that I have not used any of these examples, so I cannot vouch for them one way or the other. Here is a link to the actual asynchronous appender from the log4net Examples area

问题 The DatePattern string needs to be something that the SimpleDateFormatter will accept. Unfortunately this means that, out of the box, this doesn't include being able to set the boundary to be a week number. There are ways of getting this value in C#, but it's not obvious that we can extend the SimpleDateFormatter or provide a different implementation of IDateFormatter and use that instead (or even in a custom RollingFileAppender ). So how might we get a Log4Net RollingFileAppender to roll

问题 I'm using Log4Net and logging everytime my ASP.NET-Application throws an error: protected void Application_Error(object sender, EventArgs e) { Exception ex = Server.GetLastError(); Log.Error("An error occurred", ex); } Alas, everytime I visit a page on my application, a System.Web.HttpException is caught, "File does not exist". Here's the Stack Trace: bei System.Web.StaticFileHandler.GetFileInfo(String virtualPathWithPathInfo, String physicalPath, HttpResponse response) bei System.Web

问题 This is my error message: log4net:ERROR XmlConfigurator: Failed to find configuration section 'log4net' in the application's .config file. Check your .config file for the <log4net> and <configSections> elements. The configuration section should look like: <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler,log4net" /> this is my web.config: <?xml version="1.0"?> <configuration> <configSections> <section name="log4net" type="log4net.Config

问题 I have a log4net ado appender writing to a SQL Server database. I like it, I think it's neat. Before I send it into production, I want to know what the behaviour will be if the database goes down. I don't want the application to stop because the logging database is unavailable. I am presuming that log4net will just silently fail and not do anything, at least that's what I'm hoping. Can anyone confirm this or (better) point me to some documentation that will confirm this? 回答1: The appender

问题 I am trying to create a logging solution that involves multiple processes on multiple machines. I planned on using the UDPAppender to send all log messages to a single machine that would manage them. I have a few questions about patternstrings vs patternlayouts. Because I need to know both which machine and which process that log message came from, I want to include that in the log as well. I found %property{log4net:HostName} for hostname, and that works great. However, I don't see anything

问题 Currently my application is using log4net to log errors, the web.config for this is as followed: <log4net> <appender name="FileAppender" type="log4net.Appender.FileAppender"> <file value="c:/paypal/logs/gateway.log" /> <appendToFile value="true" /> <layout type="log4net.Layout.PatternLayout"> <conversionPattern value="%date [%thread] %-5level %logger [%property{NDC}] – %message%newline" /> </layout> </appender> <root> <level value="DEBUG" /> <appender-ref ref="FileAppender" /> </root> <

问题 How do I choose between standard tracing, Logger.NET, Enterprise Library, log4net or Ukadc.Diagnostics? Is there a situation where one is more appropriate than the other? ... what would that be? (ASP.NET, console app, Azure Cloud, SOHO, Enterprise...) What are the benefits or drawbacks? Did I miss any other major logging frameworks? 回答1: There are many similar questions here on SO: Logging best practices log4net versus TraceSource Silverlight Logging framework and/or best practices log4net vs

问题 Say I set my log4net logger's minLevel and maxLevel to FATAL and DEBUG respectively, but under some scenario I want to mute the log-items written in the WARN level, and keep all the other levels in the range active. Is it possible to somehow use 'discrete' levels of log-levels rather than specifying a range using minLevel and maxLevel ? I assume this should be simple, but I haven't found any log4net docs or examples dealing with this issue. 回答1: You can use the LevelMatchFilter on your

问题 I've looked hard for duplicates but have to ask the following, no matter how basic it may seem, to get it clear once and for all! In a fresh Console app using log4net version 1.2.10.0 on VS28KSP1 on 64 bit W7, I have the following code:- using log4net; using log4net.Config; namespace ConsoleApplication1 { class Program { static readonly ILog _log = LogManager.GetLogger(typeof(Program)); static void Main(string[] args) { _log.Info("Ran"); } } } In my app.config , I have: <?xml version="1.0"
