New filter

    I'm using log4J 1.2.5 and I'm trying to create a filter for some information. But I have a question. 

    I'm using the LoggingEvent class, and I've seen a field inside (logger) that returns a Category object. 

    I think it's the Category that called the log, isn't it? But I can't take some information that I've set
inside the Logger object... 

    Any idea?

    Thank you very much...

RE: RollingFileAppender disk full handling

Colin,

I tried a similar thing with the DailyRollingFileAppender (or for test
purposes just with the FileAppender). My aim was to ask the user to replace
the media if it is full with a new one or choose another location for the
logfile. To detect an exception or another error condition, I did add a
custom errorhandler (as Kevin suggested). But I stumbled when I wanted to
close the logfile and open a new one afterwards - I just couldn't find a
solution as 'reset' and 'close' also close the logger (and not only the
file) and after calling these functions log4j issues errormessages on the
console...

If you get any further, I would appreciate to hearing from you. 

Donat

P.S. please find below a code fragment of how I added the custem
errorhandler (LogFileErrorHandler) to all FileAppenders.

// Add custom errorhandler to all FileAppenders
Enumeration eapp = LogManager.getRootLogger().getAllAppenders();

for (Enumeration e = eapp;e.hasMoreElements();) {
   Object obj = e.nextElement();
   if (obj instanceof FileAppender) {
       FileAppender fa = (FileAppender) obj;
       LogFileErrorHandler lfh = new LogFileErrorHandler();
       fa.setErrorHandler(lfh);
    }
}

You are using a derived Logger class?

New filter

    I can't receive to my mail, but I can see the messages in mail-archives.com, so...

    Yes, I've created an extension of Logger with a protected field. Then, in the decide method of my filter, I
want to see this field for testing its value, but it seem it doesn't work... I think I'm doing somethig wrong...!

    TIA

Re: New filter


You should first subscribe to the log4j-user list. See
http://jakarta.apache.org/log4j/docs/contactUs.html for more
information.

Fwd: an AsyncAppender class


Paul,

If you omit the join operation, you have no way of knowing when the
appenders attached to the AsyncAppender have finished their work. If
thinking that the previous AsyncAppender was closed, you immediately
create another AsyncAppender that encapsulates appenders writing to
the same system resources (DB, file..) this may result in two sets of
appenders writing to the same file albeit for a short while. In the
case of databases this may result in out of order logs which is not a
big deal. However, in the case of files this may result in corrupt
files. It's a question of reliablity...

Hope this answers the question.

Yes, I've created an extension of Logger with a protected field.
Then, in the decide method of my filter, I want to see this field for
testing its value, but it seem it doesn't work... I think I'm doing
somethig wrong...!

Have you tried using the MDC instead?
