Logging from two dlls interop

Alaks — 2008-08-07T11:20:34

Hye. I wanted to trace my functions by logging some informations. So i developped two dlls (.net interop) wich use log4net for logging. when i execute one of the dlls from asp page, logging is working fine. But when i wanted to use both in the same page with "createObject("Dll1.object) and createObject("Dll2.object") i encounter problems. The problem is a little bitte weard, all functions with the same name in these two dlls , the logs is automatically logged in the last dll instantied. Example(c#) Dll1 : public void foo(){ log.Info("Hello it's me"); } Dll2 : public void foo(){ log.info("Hello it's not me!"); } ASP page : <% set ob = server.createObject("Dll1.object"); set ob1 = server.createObject("Dll2.object"); ob.foo() %> So as result i get the log file of dll2 modified with this content : "Hello it's not me!" and the log file of dll1 is not modified. And to finish, logging is working fine for the function wich has different name in these two dlls. I don't know if i explain well, but in all cases i am sorry for my english. Thank you in advance

ASP.NET, AdoNetAppender and deferred property execution

Jerry Shea — 2008-08-07T08:12:10

Hi Everyone, I am seeing a problem here which I believe is due to deferred property execution. I have a ClientLogger which gets a property value from the HttpSession as below. public class ClientLogger { public override string ToString() { string retval = "-"; if (HttpContext.Current != null && HttpContext.Current.Session != null && HttpContext.Current.Session["client"] != null) retval = (string)HttpContext.Current.Session["client"]; return retval; } } My log4net is configured with an AdoNetAppender which of course is a BufferingAppender. ... ... ... ... The problem is, when I look in my database I and compare the rows there with what I see in my log file (generated from RollingFileAppender) I can see that the property values for "client" do not match. I presume this is because my ClientLogger is not being called until the AdoNetAppender's buffer is flushed. Can anyone confirm if my diagnosis is correct, and, if so, is there a way to have these properties evaluated when the log statement is executed, rather than at flush time? Thanks, Jerry

Adding properties to a logging event

Michael Richman — 2008-08-06T19:03:51

I'm trying to add properties to a logging event so that the adoAppender can=pick up these properties and use them in the insert SQL statement. I've followed the example of creating a loggingEvent, but for the life of me, I can't figure out what the callStackBoundaryDeclaringType would be. Can someone help me figure out what the first parameter is to pass to the LoggingEvent constructor? Also, is there a simpler way to add event specific context so that the appender can pick up the properties? I know I can use MDC or NDC or thread context or global context, but these are properties that are specific to the event, not those larger contexts. My code fragment is as follows: log4net.Core.LoggingEvent loggingEvent =3D new log4net.Core.LoggingEvent(ca= llerStackBoundaryDeclaringType, log.Logger.Repository, log.Logger.Name, log4net.Core.Level.Info, "This is a Message", new Exception()); loggingEvent.Properties["Additional"] =3D "Additional info"; log.Logger.Log(loggingEvent);

Excluding stack trace from Layout

Hsalim — 2008-07-30T14:11:29

Hi, I have tried to search for an answer here and tried to understand the documentation but can't say I have been successful. I'm using this configuration value for the layout pattern: This is too much information. I don't want the stack trace, only exception.messge and exception.InnerException. How do I specify that in the layout? Thanks in advance for helping. Habib

NUnit + Log4Net Config Error

smdenis — 2008-07-30T03:37:12

When I compile my website using Visual Web Developer, it builds with no problems. I created the DLL using the aspnet_compiler on the command line and send that to NUnit. When I try to run my unit tests, I keep getting this error: log4net:ERROR XmlConfigurator: Failed to find configuration section 'log4net' in the application's .config file. Check your .config file for the and elements. The configuration section should look like:

Here's snippet from my web.config file:

Every solution I've seen on other forums says to add something to the AssemblyInfo.cs, but since my project is a website, I don't have it. I've tried everything, but I can't seem the figure out what the cause of this error is. Please help.

more loggers vs. more appenders

Freddy Gómez — 2008-07-29T19:22:58

Hi, I need to output to distinct files the events of distinct classes in my application. I have two options: Configure a logger (with only one appender inside and with the additivity set to false) for each class. Leave a unique logger (the root logger) and add one appender to this logger for each class, then use a LoggerMatchFilter (in the appenders) to drop the logging event if the class is not the specified. I don't know the underlying stuffs and cannot decide which one is better (if there is place for this question) or side effects of choosing one. I wonder if any of you have made such a configuration and can tell something about. Thanks in advance, -Freddy

Change the logging directory at runtime

Freddy Gómez — 2008-07-29T18:58:48

Hi, I'm planning to use log4net to write events in a removable usb memory. As you can suppose I have problems setting the right path for the logging file in the removable drive, there is no warranty about the drive where the memory will be mounted each time; and the application, depending on its state, it can be using different removable memories at different times. I wonder if there is any way of setting the file path of the FileAppender or RollingFileAppender at runtime. Thanks in advance, Freddy.

Change the name of the log file

Nicolas Chollet — 2008-07-29T09:20:30

Hi, My version of log4net is quite old (1.1...), and i cannot change it. I would like ton change the name of the file before using it if necessary. More precisely, i would like to change the name of the log file before calling "GetLogger". How can I? Perhaps i can use the function "SetFile", but i cannot reach it on my code. Thanks, Best Regards, Nicolas _________________________________________________________________ Pendant tout l'été, consultez vos emails Hotmail sur votre mobile ! http://www.messengersurvotremobile.com/?d=hotmail

Writing large Strings (> 4000Byte) to Oracle database

BushTacker — 2008-07-24T12:04:44

How can I write large text strings (larger then 4000Byte) to a log4net.Appender.AdoNetAppender. Up to 4000Byte it works fine with the dbType:String. But how can I write larger Strings. (Mostly used for writing stack trace to a database) Can I do it over a CLOB? ... ... ...

FW: AdoNetAppender: can not read custom properties from LoggingEvent using configuration file

Andrei Leca — 2008-07-23T12:06:04

I used a extended log using example: http://svn.apache.org/viewvc/logging/log4net/trunk/extensions/net/1.0/log4ne t.Ext.EventID/cs/src/EventIDLogImpl.cs?view=co .

how to configure a "deny stringmatch filter"

Alexander Wolff — 2008-07-20T04:55:55

the following filter: Look for the substring 'database' in the message text of the event, in the case that text is found the filter is ACCEPTED and the message is logged. OK I want to configure a filter that DENY the substring 'database' (don't log the message) how can I configure that? thanks in advance, Alexander Wolff

RollingFileAppender not working

vikram srinivasan — 2008-07-18T14:18:35

Hi All We have an app that uses log4net 1.2.0.22663. Its deployed on Win2K3 server, running on IIS 6.0. My log4net config look like,

As you can see I have set up a size based rolling over. Recently, this seems to have broken. I turned on internal debugging and got this error, log4net:ERROR RollingFileAppenderOutput stream for appender named [LogFileAppender] has been closed. Rolling over is no longer happening and logging is off until I manually roll the file over. Also, the count direction (although not set in the config) is less than 0 as I see the last rolled over file having the highest number. Any thoughts? Thanks Srini

XML configuration, windows service

Aleš Vojáček — 2008-07-17T12:11:17

Hi all, I'm using [assembly: log4net.Config.XmlConfigurator(ConfigFileExtension = "conflog", Watch = true)] in AssemblyInfo.cs Almost everything works fine. When I started service without config file there is no problem, simply service does not generate log. Then I add config file into service directory, again everything works fine, it starts logging. If I change config file then the configuration change and again everything is ok. But when I delete config file then service still loging, I hoped that it stops logging. How to do that, I know that it can be done using change config file instead of deleting it, but I need some more simple solution, because it wil be used by our customers which has no knowledge about editing files. I hoped that I will send them config file, which they simply copy into app directory, then they send me log file back and then delete config file. All without restarting service. Can you someone help me with that? A.

AdoNetAppender.ActivateOptions not using correct connection string?

Daniel Williams — 2008-07-10T17:05:24

I am using an adonetappender. THe appender is defined an a separate config file, and I use assembly attributes to load it. In my code, early on, I get the appender and set its connection string. But when I call ActivateOptions, I get an error - it seems the appender is trying to use the old, dummy, connection string that I defined in the config file. This is not what it should do. Any ideas? Is it not possible to set the connection string at runtime? I saw posts explaining how to to exactly this, and no one mentioend this issue. Cheers, Daniel

Must declare a logger in the exe?

Daniel Williams — 2008-07-01T23:40:48

I have a dll that I recently put log4net logging into. It is called by many different executables. So I wanted to find out what is the minimum I must do so that an exe will cause the logging to happen in the dll. Add reference to log4net Add [assembly:log4net.Config.XmlConfigurator(ConfigFile="log4net.config", Watch=true)] to the exe's assemblyInfo.cs That should be it, right? We've referenced the dll, and called configure using the assembly attribute. However, this does not cause my dll to log. I find that only if I declare a logger in the exe, only then will the logging in my dll start. Does this make sense? Am I missing something? I would like to know the very minimum of code changes required to get logging to work. Cheers, Daniel

Message encoding

Yann Luppo — 2008-06-27T22:49:55

Hi everyone, I have a remoting appender in place, but it looks like the encoding of the message isn't unicode or at least it doesn't support the equivalent of (char)172 because that special characters gets all weird on the server side. Is there anyway to set which encoding the logger/appender are using, specially in the case of remoting. Thanks, Yann

Default PatternLayout date format is not ISO8601

Eric Chamberlain — 2008-06-27T22:33:41

I could find no FAQ on this so I am reporting this here. Everyone repeats that %date{ISO8601} will produce ISO8601 format for dates. Beyond that, the documentation says that the default form of the %date in PatternLayout is ISO8601. This appears to be wrong based on the statement of the ISO8601 standard at http://www.w3.org/TR/NOTE-datetime. An example should illustrate the difference easily. Sample output of %date{ISO8601}: 2008-06-27 15:24:27,421 But if the above elements (down to the fractional second) are to be displayed, the ISO8601 standard says it should be (assuming Pacific Time in this sample) 2008-06-27T15:24:27.421-07:00 The ISO8601 correct format is *possible* in log4net, of course, but it is not the default. I don't know whether this is a bug in log4net or whether the documentation is just out of date or what. I will leave that for others to sort out but there is a mismatch between the documentation and the behavior.

Parsing a log generated by a RollingFileAppender with LINQ to XML

José (bluemail — 2008-06-27T22:03:10

Hello, This post is not directly related to log4net. However, I have a parsing issue with one of the generated log file. I'm currently trying to parse (with LINQ to XML) a log file generated by a RollingFileAppender. It has the format as shown at the end of this post (XML fragment, undeclared namespace). I tried to load it using the XElement.Load() method. However, it throws an exception telling me that the "log4j" namespace is undeclared. Has anyone already tried to load such a file using linq? Thanks for any feedback! José completed registering new logger for category AFCLOGGING completed registering new logger for category InternalLog .....
