We have an application that is a mix of Java and C++ code, and are wondering if we can use log4j and log4cxx together to log to the same file, assuming each is defined with appenders that point to the same file, and assuming both Java and C++ are running in the same process. Is this as simple as defining the proper FileAppenders on both the Java and C++ side, or do we have to use something like SocketAppenders? Our goal is to have a single unified log so that users don't have to try to correlate intertwined log messages from two different log files just because the log messages originated from within different code spaces.

Re: How can I know log4cxx is initialized?
Why don't you simply create a singleton instance of a class that will manage log4cxx for you? Then you can just query the singleton to see if it is initialized or not... or even just call the init() method of the singleton in all your DLL's... so the init will only happen once.

Re: How to build simplesocketserver binary file?
Since Log4CXX has a wire format that is compatible, you can download Log4J... it has a SimpleSocketServer. We use it for centralizing the logs into one file as well.

Hi Curt, Thanks for your answer. My problem is that I have several processes writing concurrently in the same log file and all of them using log4cxx API, as far as I understood the simplesocketserver binary allowed me to centralize the management of all log messages avoiding problems with concurrency, my idea was to add a SocketAppender in my log4cxx.properties file that redirects all log messages coming from the different applications to the simplesocketserver binary so it can manage that and write properly all messages in the same log file. Now you tell me that in log4cxx version 0.10 thay have dropped the distribution of this binary file, which is a bad news for me... Have you got an idea of any other application similar to simplesocketserver that I couls use for my purposes? Do you know if is possible to get the source code of the simplesocketserver binary for me to recompile it with log4cxx 0.10?

Thanks in advance, Mh In log4cxx 0.10, the binary format for the SocketAppender was changed to be compatible with log4j 1.2's, so that Chainsaw and any other application that could connect to log4j's SocketAppender. However, that support is write-only, it is fairly simple to write something that log4j can consume, but massively complicated to consume anything the log4j might produce. Since there log4cxx was compatible with log4j's binary format and log4j provides SocketReceivers, simplesocketserver was dropped. Also, The log4cxx 0.9.7 wire format was not platform independent, a x86_64 build could not connect to a x86 build or a little-endian to a big-endian. -- Wer von seinem Tag nicht zwei Drittel für sich hat, ist ein Sklave. - F.

RE: File system full causes log4cxx to crash
Peter - To add to your comments: In our systems (real-time call processing engines for carrier networks) a s/w fault is many orders of magnitude worse than no logs being available. One thing that happens in our customer environments is that when something goes wrong... the IT/sysadmin folks will look at syslog entries -- and if the appender or logger framework were to log something they'd see it.

RE: File system full causes log4cxx to crash
Peter - Sorry, been a bit busy lately, and missed this one... I don't believe it's a controllable behavior, from what I recall it is an OS level behavior on what happens when it is out of resources. I've seen apps not using Log4CXX do the same thing. Or worse, I've seen apps get stuck.

We’re using the RollingFileAppender on a Unix box. Is there some way to configure log4cxx to behave a little less drastically in a case like this?

What's happening is when the rollover occurs at midnight, some

renamed, whereas others log to the main log file as they should. I'm
suspecting that this is an error on our part and we should not have
multiple processes all log to the same file, although I've heard
that others do this. What's the solution?
log4cxx's RFAs mimics log4j's RFAs and having multiple independent
applications attempt to write to the same location is a common
misconfiguration problem in the log4j world. There is no mechanism
(at least using java.io) to detect the situation, so the best we can
do is to tell people not to do it.
You are apparently running on non-Windows platform. What is occurring
is that one application rolls over renaming the previous log file and
creates the new log file, when other applications decide that it is
time to roll over, then fail to create the new log file and continue
to write to their old handle (which has been renamed since they
originally opened it).
There has been a long stalled initiative to develop a
MultiFileAppender for log4j which may handle the situation more
gracefully (not its main objective), but that development has been
stalled for a year or so.

The most recent comments looked a new bug unrelated to the original and didn't have enough information to diagnose. I'd like to consider adding an DllRegisterServer and DllUnregisterServer entry point for NTEventLogAppender to register the message resource for the Event Log viewer. Currently the resources are attempted to be added on a logging request if they keys are not present. However, that can be a privileged operation that should be done at install time which the user may have agreed to elevated privileges. Makes sense for a log4cxx.dll, but don't think it makes sense during a static library. Probably have static members in NTEventLogAppender for the registration and unregistration and have the standard entry points just delegate to those methods.

It gives errors about nested comments in the project element. I also
noticed that ant thinks we're trying to build on Windows. The command I

-Dapr-util.dir=/export/home/renny/apr-util-1.2.12 -Dcompiler=CC

So... I switched to the autoconf/automake build...
Issue 2. Most of the headers that use LOG4CXX_PTR_DEF have a semicolon (;)
following the invocation of that macro.

Unfortunately, Sun Studio sees this as an error, and stops. I fixed it by
running the following command, which removed the semi-colon following the
invocation of the macro. I also noticed that some files already had the
correct usage.
find . -name \*.h|xargs grep -l PTR_DEF.*;$| xargs -i -t perl -i
-p -e s/(PTR_DEF[^;]*);$/\1/ {}
The only one that was missed was smtpappender.h, which apparently has lots

on it (I had not antcipated that). So I manually edited the file:

Renny Koshy President CEO I think we are close enough that getting a new developer ramped up would likely delay things unless someone wants to take on the ODBC/ DBAppender in the next week or so. However, having a configure/ autotools guru on call could be helpful. Andreas Fester has done that role in the past and I was planning on nagging him when doing the release candidate preparation. Testers checking various build platforms and testing with apps that use log4cxx 0.9.7 however would be very helpful and timely votes on any release candidates would be essential to encouraging the LS PMC to support the release.

The Logging Services Guidelines prescribe distinct votes by the subproject (log4cxx) and LS PMC, but those have been held simultaneously in previous log4j releases since it ends up as two votes by almost the same set of people. LS PMC members have the only binding votes and at least 3 votes in favor from PMC members are required. Other voters are desired, but only advisory. To get that many votes from the PMC will mean convincing members whose primary interest is log4j, log4net or Chainsaw to cross lines and vet our release, so the more advisory votes on the release would allow the PMC members to with confidence focus on just the legal and procedural requirements. If there is a community in favor of a release candidate, then working through the procedural and political issues should be achievable. If there isn't a community, then it is likely stuck.

void infof(const char *fmt, ...);
void warnf(const char *fmt, ...);
void errorf(const char *fmt, ...);
void fatalf(const char *fmt, ...);
They are each implemented as:
void Logger::debugf(const char* format, ...)
{
if(repository-isDisabled(Level::DEBUG_INT))
{
return;
}
// Format the string
va_list pvar;
va_start(pvar, format);

Fixes to Log4CXX
I noticed that Log4CXX thresholds were being ignored by 0.9.7 -- we're still using this in production environments. Has anyone else experienced this? - I fixed two bugs related to this - 1. AppenderSkeleton wouldn't handle threshold as an option - 2. FileAppender was passing the logger name instead of the option name to the WriterAppender::setOption() - I also modified the NTEventLogger to use the LineNumber param as the EventID, as that allows custom event ID's to be used (those can be trapped by NT Event Log monitoring software). If anyone is interested, I can provide the patches. Regards, Renny Koshy President CEO RUBIX Information Technologies, Inc. www.rubixinfotech.com

I'm continuing the initial cross-posting just to tell anyone interested
in following or responding to the thread to do so on
[EMAIL PROTECTED]
I think that you need to design your use of the log4X frameworks so
that they can readily evolve as you discover the best hierarchy for
your applications. The hierarchical metaphor used in the log4X is
useful, but not perfect, for configuring logging. Even a bad hierarchy
is better than individually configuring each logger.
The logging hierarchy should be designed to make typical configurations
simple to express. Configuration precedes collection which precedes
analysis. If you make configuration or collection difficult, you won't
have anything to analyze.
You should should consider the audiences for the log messages and the
frequency of the potential logging requests and their impact on
performance.
The most common audience for log4X messages are diagnosticians trying
to figure out why something is going wrong. Your audience is assumed
to be familiar with the source code for the application and fully
qualified class names make an effective hierarchy. The logging
requests are frequent and should be very low cost in normal operation.
Some other audiences would be security analysts, performance
analysts, and business analysts. Obviously one individual might be a
diagnostician in one instance and a performance analyst in another, but
thinking in terms of discrete audiences is helpful. Logging requests
intended for these other audiences are typically much less frequent, so
the need to suppress unnecessary messages for performance reasons is
much less important.
I would recommend using distinct Logger references for each of these
audiences within the implementation. For example:
public class Query {
private static final Logger logger = Logger.getLogger(Query.class);
private static final Logger performanceLogger =
MyLoggerHelper.getPerformanceLogger(Query.class);
private static final Logger securityLogger =
MyLoggerHelper.getSecurityLogger(Query.class);
}
Your implementation of MyLoggerHelper.getPerformanceLogger could start
out as simple as returning Logger.getLogger(performance) or
Logger.getLogger(performance. + clz.getName());
One problem is when a message is of interest to multiple audiences.
For example, the search metrics may be of interest to both the
diagnostician and the performance analyst. Since these would typically
be low volume, it might be simplest just to repeat the message on both
the diagnostic and performance logger. Otherwise, you might be able to
bridge loggers by routing performance.com.example.foobar to the same
appenders as com.example.foobar.

setup a DailyRollingFileAppender the application hangs. here's my
property file:
log4j.rootLogger=DEBUG, R
log4j.appender.R=org.apache.DailyRollingFileAppender
log4j.appender.R.File=/junk/JunkFilter.log
log4j.appender.R.DatePattern='.'-MM-dd
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%5p %d %c %m%n
Is this broken? Also, i don't know if it's related, but i can't
format dates in the pattern layout (something like %d{HH:mm:ss,SSS}
for instance doesn't work). And if I use simply %d, it gives me
something like this output:
INFO 2004-11-19 17:40:15,% MailFilter 127.0.0.1 [EMAIL PROTECTED]
ContentBlock viagra badmail
the SSS part of the date format is displayed as %. So i think
the format is not being interpreted correctly. I hope someone can
help me, or at least give some directions to try to correct this.
Thanks in advance,
Paulo Albuquerque

Re: Log4cxx obliterates the TZ setting...
Curt:
Added the changes to do this... (save/restore the TZ back)... HOWEVER... I'm seeing that there is some sort of static initialization that's resetting the TZ?
The following two files have my save restore code added around the tzset() these files have the tcout being used to display when I save / restore them... they should be commented out I guess...
However, I still see the following when executing my code. Notice how it goes from US/Eastern to '' ... and then to US/Eastern... and then to GMT... and the SmartACD.cpp:174 is the first print statement from MY code.. so I assume a static initializer or two is being kicked in... but where?? I don't use any static log4cxx stuff...

I had noticed the potential for the problem and logged it as
http://nagoya.apache.org/jira/browse/LOGCXX-11. Thanks for confirming
that is actually a problem. My suspicion is that gmtime or gmtime_r is
not adequate since log4cxx may need to format times to a time-zone
other than the current time zone. However, it might be an optimization
if the timezone for the layout and the current timezone are the same.
I guess the first thing is to at least reset the value of TZ to the
initial value after collecting time zone offsets.
