log4net.dll version 1.2.10.0 (FileSystemWatcher objects)

Yuvraj Raj — 2013-05-23T18:26:02

Hi,

I am application developer team supporting.NET project in Michaels Stores. We have been using log4net.dll version 1.2.10.0 for application logs for our project. The application is implemented in .NET , C# with 3.5 framework.

Recently we have faced System.OutOfMemoryException exception thrown by the application. We have opened case with Microsoft.  Microsoft analyzed and said memory consumption is due to FileSystemWatcher objects used by log4net.Config.XmlConfigurator+ConfigureAndWatchHandler which are still alive and pinned objects.

From the memory dump, They found >2000 instances of log4net.Config.XmlConfigurator+ConfigureAndWatchHandler and the FileSystemWatcher objects created that contributed this issue. The issue is happening due to the fragmentation of Gen2 Heap. The reason for the fragmentation is the pinned System.IO.Overlapped objects used by FileSystemWatcher objects.

To resolve the memory  issue, we need to get rid of the fragmentation caused by pinned objects used by FileSystemWatcher obj

How to force log4net to refresh timezone information?

Warrick Wilson — 2013-05-23T03:55:22

I've inherited a project that users log4net to do some logging. One of the
things that got noticed was that changes to the timezone on the PC that the
program runs on don't get the logging times changed (e.g. changing the
timezone from Pacific to Eastern does not change the logging time by 3
hours)

The program code that was written by "us" has routines in that trap an
event for timezone changes and call TimeZoneInfo.ClearCachedData()
(something like that... doing this from memory).

Is there a call that can be made to get the log4net "innards" to do the
same sort of thing?

ThreadID not changing

Randar101 — 2013-05-03T14:53:45

We have an application that has the following architecture:
-IIS
-WCF RIA Services.  
-Silverlight client
-We log on both the client and the server and use Clog to send the logs from
the client

My issue is with our server logs.  Whenever log4net logs the threadId, it
seems to be the same until something big happens (i.e. IIS Reset).  So the
log file looks like this even though these are two users hitting it at the
same time.

log4net with IntelliTrace

Todd Bradley — 2013-05-02T18:09:40

Has anyone tried integrating log4net with Microsoft IntelliTrace?

http://msdn.microsoft.com/en-us/library/vstudio/dd264915.aspx

That's their system for recording "events" that happened during execution of an app, such as debugger events, exceptions, etc. I haven't personally used it, but IntelliTrace sounds like it might be useful for troubleshooting distributed load tests, and we're standardizing on log4net for logging in our test code.


Cheers,
Todd.

Issues with deploying log4net

Ron Daggett — 2013-04-17T19:12:36

I'm having an issue with log4net version 1.2.9.0. When I deploy my app
locally, it runs as expected. When I try and deploy to a QA Web server,
I get the following message when I try and open the page:

log4net in medium trust ASP.NET 4.x

Andrew Arnott — 2013-01-02T15:07:54

I noticed [an issue][1] is already filed for this. But it seems to be
dormant and the proposed fix was apparently difficult. I’ve added comments
to the issue that offer two alternatives for fixing it that are both
one-liners, and both arguably a better fix than the proposed one. Can
anyone reply with whether they agree, and/or with a timeline of when we
expect this problem to be solved?

Thanks.

How can I get a simple log to write to disk as soon as the message is logged?

Rob Richardson — 2012-12-17T21:36:48

Greetings!

I have a very simple log file to generate rolling log files.  I want to ensure that log messages are readable as soon as they are generated.  My log file stayed at 0 bytes as long as my program is running, and then after the program exited the log messages appeared.  Is there a setting I can use to change that behavior?

Here's the configuration file:

<?xml version="1.0" encoding="utf-8"?>
<log4net>
  <appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
    <file value="CraneInterface.log" />
    <appendToFile value="true" />
    <maxSizeRollBackups value="90" />
    <rollingStyle value="Size" />

    <layout type="log4net.Layout.PatternLayout">
      <conversionPattern value="%date - %message%newline" />
    </layout>
  </appender>

  <root>
       <level value="DEBUG" />
      <appender-ref ref="RollingFile" />
  </root>

</log4net>


Thank you very much.

ColoredConsoleAppender defaults to black background even when the console is not black.

Justin Dearing — 2012-11-13T00:58:55

Hello,


This picture of a powershell.exe console illustrates the issue
http://i.imgur.com/0METC.png


My PowerShell prompt is blue. Those messages were sent via
ColoredConsoleAppender here is a snippet of the config file:

      <mapping>
        <level value="WARN" />
        <foreColor value="Yellow, HighIntensity" />
      </mapping>
      <mapping>
        <level value="DEBUG" />
        <foreColor value="Green" />
      </mapping>


If there is no <backColor/> I feel the background color should not be
explicitly changed. Is there any way to force the default color?

Regards,
Justin

ListViewAppender: ListView always null?

BlackMatrix — 2012-11-03T13:08:48

Hi.

Ich have written a ListViewAppender to bind my log messages to a WPF
listview control.

Always when I write a log message my application jumps to the 

        protected override void Append(LoggingEvent LoggingEvent)

method of my ListViewAppender, but the _listView is after initialization
always null.

 public partial class MainWindow : Window
    {
        private static readonly ILog log =
LogManager.GetLogger(typeof(MainWindow));

        public MainWindow()
        {
            InitializeComponent();

            ListViewAppender listViewAppender = new
ListViewAppender(listView);

            log.Error("Error.");
        }
    }

    public class ListViewAppender : AppenderSkeleton
    {
        private ListView _listView;

        public ListViewAppender()

RollingLogFileAppender skips numbers when rolling

bbell2012 — 2012-11-02T15:31:33

My log4net.config looks like this:

<log4net>
  <appender name="RollingLogFileAppender"
type="log4net.Appender.RollingFileAppender">
    <file type="log4net.Util.PatternString"
value="%property{log4net:HostName}-Athena.log"/>
    <appendToFile value="true"/>
    <datePattern value="-yyyy-MM-dd.&quot;log&quot;"/>
    <rollingStyle value="Composite"/>
    <maximumFileSize value="5MB"/>
    <maxSizeRollBackups value="100" />
    <staticLogFileName value="true" />
    <countDirection value="1" />
    <layout type="Common.Log.AwarenessPatternLayout">
      <conversionPattern value="%-5p %d %5t %-30.30c{1} %-30.30M

    </layout>
  </appender>
  <root>
    <level value="DEBUG"/>
    <appender-ref ref="RollingLogFileAppender"/>
  </root>
</log4net>

Common.Log.AwarenessPatternLayout is a custom class that extends
PatternLayout and overrides the Header property so we get some standard info
at the top of our logs.

On 10-19, everything starts out ok:

Configuring log4net for generating rolling log files with roll numbers separated by underscore

Piyush Kumar — 2012-10-12T14:03:50

Hi All,

I am using RollingFileAppender to generate log files in my application. The
generated file names are MyApp.log, MyApp.1.log, MyApp.2.log... and so on.
I want them like MyApp_1.log, MyApp_2.log, MyApp_3.log... and so on. How
can we achieve this?

My log4net appender configuration looks like -

  <appender name="RollingFile" type="log4net.Appender.RollingFileAppender">
  <file value=".\\Logs\\MyApp.log" />
  <appendToFile value="true" />
  <maximumFileSize value="15360KB" />
  <staticLogFileName value="false" />
  <rollingStyle value="Size" />
  <PreserveLogFileNameExtension value="true" />
  <layout type="log4net.Layout.PatternLayout">
    <conversionPattern value="%date %message%-5level%newline" />
  </layout>
 </appender>

Please help.


Thanks and Regards,
Piyush Kumar

CloudWatchAppender - an open source appender for Amazon AWS CloudWatch

Martin Camitz — 2012-09-11T17:57:07

Hello,

CloudWatchAppender is a new open source project targeting developers on the
Amazon cloud. It's a new appender you can plug in to log4net. You can have
your log events show up as a graph on CloudWatch monitoring service only
changing your config file. It's packed with features but very simple to
configure.

If you already have log4net config in place, adding the ClouldWatchAppender
for basic usage entails

    <appender name="CloudWatchAppender"
type="CloudwatchAppender.CloudwatchAppender, CloudwatchAppender">
        <accessKey value="YourAWSAccessKey" />
        <secret value="YourAWSSecret" />
        <endPoint value="for example eu-west-1" />
    </appender>


Try it out and by all means branch it if you feel features are missing. I'd
love some help.

Assemblies with loggers which use different config-files

Matejka, Volker — 2012-08-13T15:16:45

Hi, I have a question I could not solve: I am using log4net in an assembly B, log4net-config-file is named B.log4net. This assembly is now referenced by program A, with a log4net-config-file A.log4net. The logger-names are also different.

How can I achieve that B also uses the log4net-config-file of A (for definition of levels etc.)? I do not want to put 2 different config files in the folder... Is there another way? How is such a situation handled normally (let's say B is some kind of common library others also use).

Thanks and best regards,
Volker

Lossy logging on a per user basis for a high traffic website

Joe Udwin — 2012-08-07T10:44:15

I'm looking to setup lossy logging (on a high traffic website) on a per user (or per request) basis.
E.g The application logs nothing until an error occurs when all logs are then written to a file (or db).

I have been playing around with the BufferingForwardingAppender but it looks like it buffers all logs sent to it (not per thread or per request), so on a high traffic site this could be a combination of multiple user's log messages. On a busy site other users log messages could completely push the useful logs out of the buffer.

Has anyone done anything similar?
Are people using lossy logging on a high volume website?
Would you recommend this approach?
Any ideas how I might achieve this?

Thank you for your help in advance!

How to obtain MSIL DLL for 1.2.10 PublicKeyToken=692fbea5521e1304

Sam Carter — 2012-08-07T04:36:23




Hi all,

I have a problem with Crystal Reports for VS2010 where the redistributables install AMD64 or x86 DLL of log4net 1.2.10 into the GAC and our application is already referencing a log4net.dll as well. Using differing public key tokens or versions of log4net seems to cause a lot of resolution warnings and we have had in at least one circumstance a problem where a binary would not run as the arbitrarily chosen log4net DLL was a bad choice.

A subset of our projects can also be deployed that do not reference Crystal components. For this scenario, we can either mirror Crystal's redistributable action and install (potentially) both log4net DLLs into the GAC or my guess is I can alternatively package up a MSIL 1.2.10 DLL with the same public key token and not have to deploy anything to the GAC when I don't have to.

Is it possible to obtain an MSIL version of 1.2.10 with PublicKeyToken=692fbea5521e1304? The DLLs in the log4net archive seem to have PublicKeyToken=1b44e1d426115821 or various others but not
