RE: Using more than one logger

Hi Curl,

 

Thanks for quick response

 

- specified folder and file in properties do exist

- given write permissions to ALL in ../logs/sysmon.log file

- When i changed it to ConsoleAppender, it printed on console.

- It did NOT worked when i changed to FileAppender

 

I am using log4cxx-0.10.0 version on RHEL 3

 

Thnx,

Sandeep

Hi,

 

I removed asterics and tested, but it doesnt seem to work.

 

Config:

-----------

 

log4j.rootLogger=DEBUG
log4j.logger.sysmonLogger=DEBUG, myappender

 

log4j.additivity.sysmonLogger=false
log4j.appender.myappender=org.apache.log4j.RollingFileAppender
log4j.appender.myappender.File=../logs/sysmon.log

 

log4j.appender.myappender.MaxFileSize=100KB
log4j.appender.myappender.MaxBackupIndex=1

 

log4j.appender.myappender.layout=org.apache.log4j.PatternLayout

Program:

---------------

                PropertyConfigurator::configure(LOG4CXX_FILE("temp.properties"));
                LoggerPtr rootLogger = Logger::getRootLogger();
                LoggerPtr logger = Logger::getLogger("sysmonLogger");

 

                //LOG4CXX_INFO(logger,"info into R");
                LOG4CXX_INFO(logger, "info message");
                LOG4CXX_WARN(logger, "warn message");
                LOG4CXX_ERROR(logger, "error message");

In above program, i tried both

LoggerPtr logger = Logger::getLogger("sysmonLogger");  --> in this case, it didnt print any error while debugging with gdb

and

LoggerPtr logger = Logger::getLogger("sysmon"); ---> this given "log4cxx: No appender could be found for logger (sysmon)"

 

Please help me out

That there is a different behavior for Logger::getLogger("sysmon") than for Logger::getLogger("sysmonLogger") suggests to me that your configuration file is being read and an appender is attached to "sysmonLogger", but it is not working as you expect.  Otherwise, I'd ask you to confirm that your configuration file is really named "temp.properties".

Your configuration file does specify use of a PatternLayout, but doesn't specify a conversion pattern, but that should default to the equivalent of:

log4j.appender.myappender.layout.ConversionPattern=%m%n

To troubleshoot, I'd check the following:

Does the ../logs directory exist and does the current user have write privileges?  If the directory does not exist, log4cxx will not currently create it (may change in the future).

If ../logs/sysmon.log exists, does the current user have write privileges?

What happens if you switch from org.apache.log4j.RollingFileAppender to org.apache.log4j.ConsoleAppender?  If you get console output, then I'd then try just a plain FileAppender before switching back to a RollingFileAppender.

You did not specify what version of log4cxx you are using or operating system that you are using.  Use of log4cxx-0.9.7 is no longer supported or recommended.
