SyslogAppender "works for me" (tm) but I haven't tried 0.10.x

Steps for troubleshooting:

1) Use some other app to make sure your logging setup is correct. I suggest the 
simple command line logger from the bsdutil / util-linux project:

http://freshmeat.net/projects/util-linux/

2) Use some facility that is working and being used by other apps on the system 
before trying some custom LOCAL_X facility. Combining steps 1 and 2 you should 
be very confident that you are watching the right file before moving on to step 3.

3) Write a simple log4cxx test app and try it. The attached one requires no 
external config and works fine on my systems with log4cxx 0.9.7.

Are you using log4cpp or Apache log4cxx?  If you are using log4cpp,  
you should go to their mailing list.

TimeBasedRollingPolicy does not work in RollingFileAppender

I used TimeBasedRollingPolicy to rollover log file every day but it did not
work. No files was generated. My configuration file is shown below,

<?xml version="1.0" encoding="UTF-8" ?> 
<log4j:configuration xmlns:log4j='http://logging.apache.org/' debug="true">
  <appender name="ROLLING"
class="org.apache.log4j.rolling.RollingFileAppender">
            <rollingPolicy
class="org.apache.log4j.rolling.TimeBasedRollingPolicy">

              
            </rollingPolicy>
    <layout class="org.apache.log4j.PatternLayout">

    </layout>

  </appender>
  <root>
    <level value="info"/>
    <appender-ref ref="ROLLING"/>
  </root>
</log4j:configuration>

And in the code, I used the following codes to initialized the log4cxx:

string strXmlConfig = "logging.xml";
log4cxx::xml::DOMConfigurator::configure(strXmlConfig);
log4cxx::LoggerPtr pLogger = log4cxx::Logger::getRootLogger();

Does TimeBasedRollingPolicy work with MaxBackupIndex?

I used TimeBasedRollingPolicy of RollingFileAppender to rollover log file
every minute. And at the same time I'd like to use MaxBackupIndex to set the
max number of backup files. But MaxBackupIndex does not work.
TimeBasedRollingPolicy cannot work with MaxBackupIndex or my configuration
file has some wrong? I attached my configuration:

<?xml version="1.0" encoding="UTF-8" ?> 
<log4j:configuration xmlns:log4j='http://logging.apache.org/' debug="true">
  <appender name="ROLLING"
class="org.apache.log4j.rolling.RollingFileAppender">
            <rollingPolicy
class="org.apache.log4j.rolling.TimeBasedRollingPolicy">

            </rollingPolicy>

    <layout class="org.apache.log4j.PatternLayout">

    </layout>

  </appender>
  <root>
    <level value="INFO"/>
    <appender-ref ref="ROLLING"/>
  </root>
</log4j:configuration>

log4cxx::net::XMLSocketNode

Hi,

What "class" can be used in log4cxx 0.10.0
instead of log4cxx::net::XMLSocketNode from 0.9.7.

I have a code, which receives packets from XMLSocketHubAppender
or XMLSocketAppender and the code work on them.

is it possible to log to the same file from log4cxx and log4net?

hi all,
    i have to log from two parts of the same application -one writen in
c++, the other in c#. We are using log4cxx in c++ section, and i would
like to add to the same file from c# module so i configured log4net to
use the same file (both using a RollingFile Appender). But i can't get
my .net messages into the file. I don't get any messages, but i have
stopped c++ logging and was able to see the messages from c# so i know
it works.
    I think it is a locking issue. I came into MinimalLock configuration
setting for log4net, but it seems that there is no correlative in log4cxx.

Does anybody knows if this cross-logging could be achieved? and if so,
how? Is there a config parameter or command to control the locking in
log4cxx?

Thanks in advance

LOGCXX-282 patch

Hi,

I see issues as described in LOGCXX-282. Will there be a release
containing
the patch soon?? Afaik, the patch isn't in the trunk, is it?

I need log4cxx in productivity on remote mashines, thus it should work
deterministic.

Cheers
