You can configure log4net anywhere - in main service EXE, in DLL which really does the job.... The only condition is to configure logging system before its first use. You can create Init() method somewhere in Logutil.dll to configure logging system and call it during application startup. If there is problem to configure logging using app.config file, try to use the second way using separate config file to check if it works - if not, you have probably error in code related to config file location.

What about a system where you have a "bank" of loggers? First, you could have an array which would contain three values; the generated logger name, a flag indicating whether the logger was being used, and a task ID (empty if the logger was not being used). Whenever you need a new logger, you check to see if one is available. If not, you create it and add an entry to the logger array. Either way, you just call the RemoveAllAppenders() method on that logger, create an appender and attach it to the logger, set the task ID for the logger, and mark it as not available. ________________________________ From: Mark A.

I've been following this thread and wanted to suggest that you consider the possibility of using the MSMQ or ADO appenders for this purpose. Both appenders, by the very nature of MSMQ and Database servers, allow for multiple, simultaneous connections and would afford a seamless, high level mechanism for gathering log messages from multiple applications, or across multiple load balanced or clustered servers into a single, serialized repository. In the case of MSMQ, you'd need to write a very simple .NET Windows Service application that drains the queue and serializes the log messages into a single file (or other repository). In the case of the ADO.NET appender, you'd need to perform and ad-hoc query, or write a very simple application to fetch log messages from the DB. Both these solutions a little (really small) bit more work, but ultimately, far more flexible and better suited to gathering and distributing log messages from multiple applications and/or servers in an enterprise environment.

Actually I have been looking at the code. Sometimes it's easier to do it in Reflector since you can easily drill down and also find where methods are called from. In any case, my major problem was to clean up the ILogger objects when I was through with them. Since that didn't seem possible, I did as you suggested and modified my code to create separate repositories. One for each task. The first problem was checking to see if the repository existed (without catching exceptions which are slow). LogManager doesn't seem to have a .RespositoryExists method, but I was able to achieve it through some typecasting. I wound up doing something like this. ILoggerRepository loggerRep; if (((DefaultRepositorySelector)LoggerManager.RepositorySelector).ExistsRep ository(TaskID.ToString())) { loggerRep = LogManager.GetRepository(TaskID.ToString()); } else { loggerRep = LogManager.CreateRepository(TaskID.ToString()); } It isn't pretty, but it did the job. I suggest someone add a ExistsRepository to the LogMan

Radovan, LogUtil.dll This has some custom logging as well as log4net dll reference and uses a custom appender to log. This is where I perform Myservice.exe has the following dll's that it uses - Dosomething.dl -à uses Logutil.dll and is included as a reference. - Myservice.exe.app.config From your information, I assume I should do this in LogUtil.dll and in the default cstor of Logutil, I should obtain the path to the myservice.exe.app.config path and set it. log = LogManager.GetLogger(typeof(LogUtil)); in the cstor Myservice.exe does not need to do any logging, only DoSomething library needs to perform the logging. The error I get is a generic .Net framework error showing all the assemblies which caused the error which may be due to versioning but the logs do not indicate this. So I did a clean install and that error was no longer the case but then it came down to just a system violation error each time I try to perform xmlconfigurator.configure() in

The source code to log4net is available at: http://svn.apache.org/viewvc/logging/log4net/trunk/src/ If you're wondering how something works that may be a better place to look. Most (all?) of the source is commented. Its acceptable to create a new repository for medium to long running tasks. When you shutdown the repository it automatically shuts down all of its appenders and loggers. ----- Original Message ---- From: Mark A.

I'm not sure you're completing understanding my dilema. I need to basically create loggers on the fly which are associated with separate files. I did actually get something working, but now I can't figure out how to clean up. This is what I have so far. To start I create a repostitory and give it a name. I then store the repository pointer in a static variable. Then when I start a specific task, I use the repository to create a logger and I add a file appender to that logger. The file appender is associtated with a unique file name. My task has a unique id and I used tha same id to name the logger. All my logging for that task uses that logger with that name and everything seems ok. Now here's the problem. When my task is done, I would like to clean up that logger and remove it from the repositry, but there doesn't seem to be a way to do this. I fear that based on my design, if my server is running for days on end, the hash table where the loggers are stored in the repository will grow and g

Re: Using log4Net to log multiple files by different users/tasks

Ron Grabowski — 2008-10-05T15:51:28

In your code the File property gets set when the Appender is created. Here's an example showing how to set the File property based on each logging event: http://svn.apache.org/viewvc/logging/log4net/trunk/examples/net/1.0/Appenders/SampleAppendersApp/cs/src/Appender/PatternFileAppender.cs?view=markup That example code is probably slow. log4j and nlog have file appenders that keep the most recent files open so you don't have to pay the open/close penalty. You could probably extend the FileAppender and override a method or two to do what you want. ----- Original Message ---- From: Mark A.

I have an asp.net site in which different users run different tasks. Each individual task is managed by a TaskManager that I'm writing. While each task is running it has the opportunity to log to it's own log file. I'm trying to use Log4Net to do this, but so far I've been unable to figure out how exactly to accomplish this. Any advice would be appreciated. So far, I believe I must create an individual Appender for each task. Something like this. PatternLayout layout = new PatternLayout("%date{dd-MM-yyyy HH:mm:ss,fff} %5level [%2thread] %message (%logger{1}:%line)%n"); FileAppender appender = new FileAppender(); appender.Layout = layout; appender.File = "d:\\logs\\" + TaskID.ToString()+ ".txt"; appender.AppendToFile = true; appender.Name = "File"; appender.Threshold = log4net.Core.Level.All; appender.ActivateOptions(); And I know that eventaully, I'll want to code to call something like ILog _Log = LogManager.GetLogger(TaskID.ToString()); But I can't figure out how to make that logger unique and how
