问题 EDIT 2 : I have solved the problem (see answer below) Please note that the problem potentially affects all appenders decorated with BufferingForwardingAppender as well as all appenders inheriting from BufferingAppenderSkeleton (respectively : AdoNetAppender, RemotingAppender, SmtpAppender and SmtpPickupDirAppender) * I was doing some very basic benchs of log4net and I tried to decorate a RollingFileAppender with a BufferingForwardingAppender. I experience terrible performance going through

问题 In my current project i want to create log files date wise i.e. log files should reside inside folder having name as date. Also archiving should happen at that particular folder. Current appender that i am using looks like this (it does archiving of log file based on size). <appender name="AUDITFILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${PROJECT_HOME}\\projectname\\audits\\myproject.log</file> <append>true</append> <rollingPolicy class="ch.qos.logback.core.rolling

问题 I have implement a custom log4net appender by extending the AppenderSkeleton-class. It was as simple as anyone could ask for and works perfectly. My problem is that I had to hardcode a few values and I'd like to remove them from my code to the configuration of the appender. Since log4net knows how it is configured I think there should be a way to ask log4net for it's configuraion. My appender could look something like this: <appender name="MyLogAppender" type="xxx.yyy.zzz.MyLogAppender">

问题 I am using Log4Net API in my application to log any important event or information as well as logging my exceptions in database. There might be an exception while using Log4Net API; if it fails to perform logging into database then how will this exception be stored? Where will all other logging and exception logging be stored in case the Log4Net API fails to perform logging? 回答1: Log4net will fail silently so that the primary function of the application is not disturbed. If you have an event

问题 I have a logger that send log to a log server storage. This work fine but the patternlayout isn't used. With or without that doesn't change anything. I believe remember to read somewhere that socketappender use is own pattern and not others. <appender name="LOGSTASH" class="org.apache.log4j.net.SocketAppender"> <param name="Port" value="5000"/> <param name="RemoteHost" value="192.168.81.131"/> <param name="ReconnectionDelay" value="5000"/> <param name="LocationInfo" value="true" /> <layout

问题 When I compile my spring 3.2.9 web application using log4j 2.1, this error appears in the console: 2015-02-02 12:08:25,213 ERROR appender Failover has no parameter that matches element Failovers What I understand is that the element "Failovers" does not exist inside the element "Failover", right? Why would this happen? I don't see whats wrong since I have the same configuration as the log4j2 manual. I have this configuration in my log4j2.xml: <?xml version="1.0" encoding="UTF-8"?>

问题 HERE It says that - "Appenders should specify printObject as "true" if the toString method renders the values of the attributes passed to the Appender." Can someone please explain this? Does this mean that if printObject=true, we should override toString() method? And what if we do not override toString() ? 回答1: During Log4j 2 initialization, all plugins in the configuration are processed and stored in Node objects. The Node.toString() method is implemented such that if the original Plugin's

问题 I started to play with log4net today and so far, I really like it. In order to preserve our current logging functionality, the app needs to create a new log file whenever the application is started. The log file name has the date and time stamp encoded in it. Currently, I've got log4net configured via an XmlConfigurator , which works great, except that the filename for my RollingFileAppender is hardcoded in the configuration XML file. I'd like to continue to use the XmlConfigurator , but

问题 Is there a way to programatically create a RichTextBoxAppender using log4net? In other words no xml app.config? 回答1: using System; using System.Windows.Forms; using System.Drawing; using log4net; using log4net.Core; using log4net.Appender; using log4net.Util; namespace Vip.Logging { /// <summary> /// Description of RichTextBoxAppender. /// </summary> public class RichTextBoxAppender : AppenderSkeleton { #region Private Instance Fields private RichTextBox richTextBox = null; private Form
