Can I have time stamp in log file name?
Hi,
Can I have time stamp in log file name?
To elaborate, if my entries in the property files are:
...
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=../logs/example.log
..
Now, I want that instead of log file name: example.log, I want the name as
example.log.<time> of creation, is there any way to accomplish this?

I withdraw the question. I have found the error. In the .so file, the
configure was not called correctly. My mistake, and sorry for this.

No appenders could be found for logger
Posted by Ambarish Mitra <am...@persistent.co.in>.
Hi,
I have written two separate and independent test programs to implement the
log4cxx functionality, one is a stand-alone EXE and the other is a shared
object (.so). The EXE is working correctly, and the shared object is
outputting:
No appenders could be found for logger (Test_so).
Please initialize the log4cxx system properly.
Both of these are using the *same* properties file. I have written another
small EXE that just calls the function exposed by the shared object, that's
all. [the shared object has the logging mechanism of log4cxx]
The snippet of the properties file is given below. Please advise if I am
missing something. {OS: Solaris 8; compiler: gcc 3.3.2}
log4j.rootLogger=debug, stdout, R
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
# Pattern to output the caller's file name and line number.
log4j.appender.stdout.layout.ConversionPattern=%5p [%t] (F:L) - %m%n
log4j.appender.R=org.apache.log4j.RollingFileAppender
log4j.appender.R.File=../logs/example.log
log4j.appender.R.MaxFileSize=100KB
# Keep one backup file
log4j.appender.R.MaxBackupIndex=1
log4j.appender.R.layout=org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%p %t %c - %m%n
Regards,
Ambarish.
Re: Can I have time stamp in log file name?

AFAICT, the closest to what you are looking for would be the
DailyRolingFileAppender - it automatically renames old example.log to
example.log.date format at midnight, when the new day file is created.
But, then there are few (significant) catches - there is no option to
automatically delete old files (really a pain). Also, it has been
deprecated in log4j (in favor of using strategy design pattern, I
believe), so I guess it will go away in log4cxx as well.
