Implementation and usage of logger wrapper for log4net

由 旧城冷巷雨未停 提交于 2019-12-28 18:11:55
问题 This question is related to Steven’s answer - here. He proposed a very good logger wrapper. I will paste his code below: public interface ILogger { void Log(LogEntry entry); } public static class LoggerExtensions { public static void Log(this ILogger logger, string message) { logger.Log(new LogEntry(LoggingEventType.Information, message, null)); } public static void Log(this ILogger logger, Exception exception) { logger.Log(new LogEntry(LoggingEventType.Error, exception.Message, exception));

日志框架 NLog

这里按老规矩先进行和其它产品进行比较： 目前在.net平台存在两个比较老牌的日志框架分别为Log4net和NLog。 我们进行对这两种框架进行比较下 Log4net Log4net是一个老牌的日志框架，它可以实现日志多目标输出，输出到控制台、文件、数据库、系统事件、Email等，几乎无所不能。它可以通过配置让日志系统实时生效，比如说在服务运行的过程中修改配置改变输出目标，改变日志等级等，均不用重启程序。存在的缺点就是配置繁琐，基本上不查资料我是配置不出来的。 NLog NLog是和Log4net差不多的日志框架，属于新兴的日志框架。我们从它们的支持和性能方面来比较下。 借鉴博客园大佬们测试的结果 我原先差点就信了，后来作者又在2017年9月1日发出以下内容。 以上性能测试不再有效，根据网友反馈，由于输出内容的略有差异导致上面性能测试出现不公平的情况，log4Net在输出时可能会有更多的计算量。在优化测试代码情况下，仅让日志框架打印日志内容，其余的包括时间、日志等级、日志类名一律不打印，使用最新版Dll，两个框架性能相差无几。 毕竟是老牌子的日志框架，居然还输给新人啦。 但从更新速度来说，Nlog一直处于持续更新中，支持的也比较多。所以我们还是在这里讲下。 先用nuget 加载下NLog 加载后我们来看下项目里面多了些神马？ 日志的配置(摘抄) 通过在启动的时候对一些常用目录的扫描

Configure Log4Net in web application

问题 I have this code and the config file below: ILog log = LogManager.GetLogger(typeof(MyClass)); log.Debug("Testing"); TestProj directory is not created and if I create it, no TestLog.txt file, no log ... nothing. Any idea? Thanks, The config file <section name="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" /> <log4net debug="true"> <appender name="RollingLogFileAppender" type="log4net.Appender.RollingFileAppender"> <file value="C:\\TestProj\\TestLog.txt" />

How to log stack trace using log4net (C#)

由 生来就可爱ヽ(ⅴ＜●) 提交于 2019-12-28 03:04:38
问题 How to log stack trace with log4net ? I am using .Net version. They way I have is Log.Error(ex) . Thanks 回答1: 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 to log exception data

Log4Net Logging of two different levels to two different appenders for the same logger

由 烈酒焚心 提交于 2019-12-28 01:52:06
问题 We have two different asp.net applications with Log4net logging enabled. They both have the same version of Log4Net, 1.2.10.0. We have added the log4net.Appender.AdoNetAppender logger to both of them and want to log Info level to it for the root logger, but also want to log to the Error level for a root logger to a file appender. Our configuration is as follows; <?xml version="1.0" encoding="utf-8"?> <log4net> <appender name="filelogAppender" type="log4net.Appender.RollingFileAppender" >

使用Log4net记录日志

由 亡梦爱人 提交于 2019-12-27 18:49:43
使用Log4net记录日志 首先说说为什么要进行日志记录。在一个完整的程序系统里面，日志系统是一个非常重要的功能组成部分。它可以记录下系统所产生的所有行为，并按照某种规范表达出来。我们可以使用日志系统所记录的信息为系统进行排错，优化系统的性能，或者根据这些信息调整系统的行为。 Log4net是一个很著名的开源的日志记录组件。官方网址为： http://logging.apache.org/log4net/ ，使用Log4net能够很简单的为我们的程序添加日志记录功能。下面我们先通过一个网站例子来说明如何在.net中使用log4net。 创建日志记录步骤 第一步， 当然是添加log4net.dll的引用啦，我这里提供一个log4net的dll文件，懒得去官网下的可以到这里下 http://www.vdisk.cn/down/index/7509396A7366 第二步， 在AssemblyInfo.cs文件中添加下面一句话： 1 [assembly: log4net.Config.XmlConfigurator(ConfigFile = "Web.config" , Watch = true )] 这句话的意思是log4net会自动寻找配置文件App.config或Web.config从而获得并加载其中的配置信息

How to configure log4net programmatically from scratch (no config)

由 南笙酒味 提交于 2019-12-27 10:20:11
问题 This is a Bad Idea, I know, but... I want to configure log4net programmatically from scratch with no config file. I'm working on a simple logging application for me and my team to use for a bunch of relatively small departmental applications we're responsible for. I want them to all log to the same database. The logging application is just a wrapper around log4net with the AdoNetAppender preconfigured. All of the applications are ClickOnce deployed, which presents a small problem with

Add a custom property to a LoggingEventData programmatically

由 老子叫甜甜 提交于 2019-12-25 16:36:10
问题 I am creating a custom wrapper for log4net. I am trying to fill my LoggingEventData object and there are some custom properties I want to pass to the Appender's append Method. However, this these properties are intermediate properties, so I don't want them to be in the appenders configuration. LoggingEventData.Properties is a read only dictionary. Is there a way get a value in there for me to pass a custom property (via LoggingEventData) to the appender WITHOUT having to update the appender

RemotingAppender problems. Conn created but nothing appended

由 喜夏-厌秋 提交于 2019-12-25 07:01:55
问题 I have been learning log4net and wish to use the remoting appender to log messages onto a server sometime in the future. To do this, I first tried creating a local .Net remoting server and appending to it. It seems to me that the server has been created but I cannot receive these messages. (To check this, I try accessing the server by entering localhost:portnumber in my browser, before and after running my program. It fails before and accepts the connection later. Any better way to debug this
