log4net versus TraceSource

In this thread many people have indicated that they use log4net. I am a fan of TraceSources and would like to know why log4net is used. Here is why I like trace sources: Pluggable listeners - XML, TextFile, Console, EventLog, roll your own Customisable trace switches (error, warning, info, verbose, start, end, custom) Customisable co...

Why is the date appended twice on filenames when using Log4Net?

I was trying to add the date to my log file name and I was able to make it work by following the few suggestions I've found in stackoverflow. Everything works fine but for some reason, the first file always has the date appended twice. For example, instead of log.2009-02-23.log, I get log.2009-02-23.log.2009-02-23.log. I found it so weir...

forward from log4net to NLog

In my current project I'm using two libraries where one is using log4net and the other NLog for its logging. I'm personally prefer NLog so it is used in my application as well.

Log4Net: Rolling File appender, define extension

Hi, I want my logfile to look something like this: 2009-02-13.log but the problem is that I can't seem to find any way to add the .log extension. I've tried a lot of things but nothing helps.

ThreadContext property does not write to AdoNetAppender

I am using log4net 1.2.10.0. I have extended ILog and LogManager to include a new level, 'AUDIT'. I want to use an AdoNetAppender to log the %message to a database.

I am setting up an SMPTAppender to email log files when there is an error in production code. There are some machines, such as test machines that are local, where I don't want the email sent.

Maximum Filesize of LogFileAppender in Log4Net

I am using Log4net for a while now and it's an amazing logging framework, especially when hooked into Castle.Windsor. However... I usually use the rolling file appender, but this has resulted in too many log files than I actually want, so instead, for my latest project, have used the basic LogFileAppender instead, but the problem is th...

Changing the Log4Net Root Level When App is built as Release

I have a project I am working on using log4net, and it works great, but I want to know if i can override the XML configuration for the root "level" attribute for the logging when in debug and release. Currently my root configuration looks like: <root> <level value="WARN"/> <appender-ref ref="LogFileAppender"/> <appender-ref ref="...

log4net configuration with [assembly:]

I was curious how the following line works for configuring log4net in an assembly: [assembly: log4net.Config.XmlConfigurator(Watch=true)] I'm guessing this gets called sometime before the runtime invokes "main()" but when does this occur, and what are the implications? Are there other frameworks/libraries that use this assembly attri...

Changing the log level programmaticaly in log4net?

Is there a way to set the log level in log4net programmatically? I'd assumed that there would be a property that would let you do this, but I can't seem to find one. What I want to do is have a configurable option to enter debug mode. which would cause extra logging. I'm using a separate log4net configuration xml file. At the moment th...

Eliminate Duplicate Logging in log4net

I have a program that makes many log4net calls to the "myprogram" loggers. It also calls other code that makes log4net calls to other loggers. I want to capture all logs higher than INFO for "myprogram" and all logs higher than WARN for everything else. This way, I get the work-in-progress messages specific to the task I'm working on, bu...

ASP.NET Logging - log4net or health monitoring?

Where to log from a .net web app? - Can't use %APPDATA% because of privileges

I need a path I could specify in log4net file appender so that the log files would go there. However, aspnet or whatever account does not have write privileges to %APPDATA% folder. Is there any place I can write to without asking customer admins to give extra access privileges? Path.GetTempFile() is probably not a good idea. I need some...

how does one troubleshooting log4net when it stops logging

It seems that Log4Net silently shuts down for reasons that are not obvious, and I'm at a loss how to troubleshoot it. My hunch is that a particular appender is failing on a specific log message and that seems to shut down the whole stack. Is there a way to get Log4Net to throw an exeception (at least during our debug phase) rather than...

log4net argument to LogManager.GetLogger

Why do most log4net examples get the logger for a class by doing this: private static ILog logger = LogManager.GetLogger( System.Reflection.MethodBase.GetCurrentMethod().DeclaringType); Rather than just passing typeof(MyClass): private static ILog logger = LogManager.GetLogger(typeof(MyClass)); Is there any other reason fo...
