RE: Error while starting second instance of application
Hi, Do you think maybe that you should only use one instance of your application? Or try and generate a random named file that feeds a general log file on exit? You are probably getting this as you are specifying the same filename for each instance in either your code or you .config. Have a think about what it is you are actually trying to do right now.

RE: Error while starting second instance of application
I am sorry, but this doesn't seem to make sense to me. Are you suggesting that you would like a logging mechanism to log errors generated by log4net? If that is the case, are you sure you haven't over-engineered your application? What Robert is suggesting is sound, simply have the logfile open when you are logging and then lose the lock after this has taken place.

I wouldnt be able to delay the configuring the logging. Instead if it would be possible to suppress the error popping up in notepad or better yet to redirect the error to a log file without it being displayed to the user, it would be great.

That is, If user X logs in, I like to create file name X and all error for user X should be written in X.log. Siilarly if Y user logs in the log file should be in name of Y.log and the most important point to note is, they could log in concurrently. I tried the luck by creating log files whose name would be framed dynamically as soon as the user logs in. But issue here, if they are not using the application at the same time, the log files are creeated with correct name and writing as expected, but if both users have active sessions, log file is created only for user who FIRST logged in and error of second user has been recorded in log file that is created for FIRST user.

Ron Grabowski sent a good example of how to do what you want to do, to which
you replied. Failing that, just include two rolling fille appeneders in your

and then a different level for everyone else.

Coming to logging. I need to use RollingFileAppenders for both of the Logs.
When you say two logs, its one for the Application Developers who needs to get
complete information for them to track.
And the other log is for the Tivoli server which keeps tracking the information
of the logs.
And from UI I normally use only one statement saying
Private readonly log4net.ILog Log = log4net.logManager.GetLogger(“”)
Log.Debug(GetformatedMessage(“Application”));
Log.Debug(GetformatedMessage(“Tivoli”));

Reducing the timeout may lead to events getting lost, but I prefer that to our application hanging for the full CommandTimeout waiting for the database to become unlocked. Is it possible to configure the timeout using configuration? or would it be better to choose for a solution like deriving from the AdoNetAppender and add the functionality?

Ross,
I guess that's why I'm posting here, because I'm trying to devise a
pattern and some coding guidelines so that all our applications log
consistently. I considered wrapping log4net but all I've read advises
against that. So what I'm trying to achieve is an elegant solution that
makes the best use of the framework.
You're right, I wish to log a collection of Key-Value pairs associated
with a given loggin event. e.g.
statistics -
eventDataduration3ms/durationsize10kb/size/eventData
details -
eventDatacustomerID3/customerIDorderID10/orderID/eventData
The question I'm asking is how best to implement this with log4net?
Should I write a wrapper or a helper class that accepts the key-Value
pairs collection as a parameter and returns a formattred XML string that
then get's logged?
Maybe I should be creating a LoggingEvent in code manually, adding the
Key-Value pairs to the Properties collection and then using
ILog.Logger.Log to actually log the event rather than using Ilog.Info()
to log. I could than write a custom layout class that serialises the
properties out as an XML string.
like I said, I'm not sure and am looking for some disrection.
Ideally I would have the following interface available to me:
ILog.Info(string message, Dictionary customProperties)
and then it would be the configuration that drives how the
customProperties are rendered by specifying the approporiate Layout
class. That way I could format the customProperties to a file in one way
and to a Db as XML etc... without embedding the formatting logic in my
code.

However this does not work (I no longer get anything output to my log file when I make that change). I understand that one can programmatically construct a full path from the base directory, but there is surely a way to specify a relative path directly in the web.config file? I have tried modifying the string using leading slash (and backslash), etc. to no avail, and could not find a solution anywhere. Does anyone know how to do this?

Hi Ross, all
some more details about my setup:
- WinForm application
- Use of Windows Workflow Foundation for customer specific jobs
We use log4net for “normal” application logging. Now I need a solution for
generating protocols for the jobs (workflows), meaning, which action were made,
errors, and so on. These jobs run maybe once a week, a month or so. Each job
should get its own protocol file. My decision for using log4net for that, too,
was primarily based on the flexibility log4net offers for defining what gets
logged and where. I can activate tracing for these jobs on the fly and I can
switch to a different appender and write everything to the database. Currently
there is no real process in “analyzing” the protocols. The customers simply
want them and sometimes we need them for debugging.
I’m fine with using my “own” appender, I was just looking if I missed some
small configuration value or something like that.
Thx to all for the suggestions and quick responses,
Wolfgang

Are you using the same logfile for every job? That seems a touch awkward to me

After these jobs are run and the log files are written, what's your process

some automated notification process? If it's the latter, I really like Karim's

You could use a getter to run the configurator, like the following:

You could use a getter to run the configurator, like the following:
private static ILog _log = LogManager.GetLogger(typeof(Program));
public static ILog log
{
get
{
if(!log4net.LogManager.GetRepository().Configured)
log4net.Config.XmlConfigurator.Configure(new
FileInfo(AppDomain.CurrentDomain.SetupInformation.ConfigurationFile));
return _log;
}
}
This way, your logger will only get configured (and the file subsequently made)
if something is logged.
Is it a hack? Absolutely. But it's the quickest way I could think of to
answer your question. :)

LogLog.Warn( FileAppender: Are you using FileAppender instead

I would prefer a solution, where I don’t have to use my own appender, but at
least I have a workaround.

I want to create protocols for jobs that can be executed in our application,
preferably one file per job and execution. But I don’t want a file, if the job
is not executed. The jobs are only executed once a month for example.
Thx for the quick response !

Hi There,
I dont think I have an answer to your question just now - but can I ask why you
would prefer to defer creating the log file?

Date: Fri, 31 Jul 2009 16:15:28 +0200
Hi Everbody,
I’m looking for a way to defer the creation of the log file until the first
entry is logged. I want to use log4net for writing protocols for jobs that can
be executed in my application. With my current configuration the file is
created during startup which makes no sense if the job doesn’t run.
My current configuration:
appender name=… type=log4net.Appender.RollingFileAppender
file value=. /
appendToFile value=false /
rollingStyle value=Date /
datePattern value=_MM_dd.\tx\t /
staticLogFileName value=false /
threshold value=INFO /
layout type=log4net.Layout.PatternLayout
conversionPattern value=%date;%level;%m%n /
/layout
/appender
One possibility seems to be to generate the appender programmatically, but then
I lose a lot of flexibility. Another one is writing my own appender (or
subclassing an existing one). Is there another way ?
Any help is appreciated,
Wolfgang

RE: Please release a version that is officially endorsed by the ASF
Log4net is used all over the world by a multitude of different organisations in any number of applications. I use it at work in production systems - my bosses trust me enough to understand that I am not going to suggest duff technology. It's up to you to make the case by illustrating the many, many successul applications of log4net across the world.

RE: Key cannot be null error
Hi Gary, I have access to an SQL Server, so I will try out my code against it later this evening. If you did follow my post on DevShed, then we will more or less have the same code.

I have attempted to track down the problem with the log4net source, but this doesnt seem to have yielded much success. I am thinking that this could possibly be an error with MySql connector as opposed to log4net, after all this doesnt seem to be happening with SQL Server or Oracle (or at least it isnt being reported). Karim, I think I followed your example on DevShed concerning this setup, I would like to thankyou for putting that together and I look forward to reading your blog article on this, I hope one of us will be able to overcome this problem - unfortunately, I dont have access to another DB to test this out on, but it would be nice to hear back from someone using the same code with Oracle or SQL Server.

SystemNullReferenceException usgin log4net with MySql
Hi There,
I have been working with log4net now for a few weeks, after some work I have
managed to use the ADONetAppender to log to a MySQL DB. However, although I can
get messages into my DB, I am getting the following error on my console:
