log4perl seems not to work as advertised	Can't Post

Hi All

I have this sample program:

Code

  
 
use strict;  
use warnings; 
use Log::Dispatch::FileRotate;  
use Log::Log4perl qw(:easy);   
my $config = $ENV{'CONFIGPATH'}; 
Log::Log4perl::init( "$config$\/testRotate\.conf" );  
my $logger = Log::Log4perl->get_logger;   
for (my $i = 1; $i<10000000;$i++) 
{ 
 $logger->info ("TESTING ROTATE $i for 10,000,000 times"); 
}

and this config file:

# testRotate-logger.conf
log4perl.rootLogger = INFO, AE
log4perl.appender.AE = Log::Dispatch::FileRotate

log_dir = /mydir/logs/
log4perl.appender.AE.filename = ${log_dir}/testRotate.log
log4perl.appender.AE.mode = append
log4perl.appender.AE.Logfile.max = 5
log4perl.appender.AE.Logfile.size = 1000000
log4perl.appender.AE.layout = Log::Log4perl::Layout::PatternLayout
log4perl.appender.AE.layout.ConversionPattern = %d %p %m %n

The Logfile.max and Logfile.size just don't work and the package seems to ignore them and use 2 files and 10000000 size

any idea

Code

Log::Log4perl::init( "$config$\/testRotate\.conf" );

This statement probably produces a run-time warning. Perl tries to form the file name by concatening the contents of the scalar variable $config (which does not exist) with the special variable $\ and then with '/testRotate.conf'

I am not sure what you intend. You must fix the quotes and escapes to specify what you really mean.
Good Luck,
Bill

$config actually exists and is correct

my $config = $ENV{'CONFIGPATH'};

the string

$\/testRotate\.conf

is obviously a mistake (I left a code from previous attempt to resolve the issue) so the correct line is:
Log::Log4perl::init( "$config\/testRotate\.conf" );

which corretly points to the configuration file above.

BTW, I tried with and without the 'easy' option, with and without the 'INFO' instead of $logger->info, etc. None changed the behavior of ignoring the 'size' and 'max' attributes in the configuration file.

log4perl still appears not to be working as advertised!!!

Thanks

ZA

Sorry, I cannot help with the module. The filename looked wrong so I wrote a tiny script to confirm its behavior. ($config did not exist in my script and I forgot to check in the original).
Good Luck,
Bill

Error resolved:

log4perl.appender.AE.max = 5
log4perl.appender.AE.size = 1000000
