Hmm, OK. Here's my first try with Log::Dispatch . It fails : the final log file holds a mixed content of only one script and the end of the launcher logs .

I will try with Log::Agent ("dispatch" seems aimed at the opposite, that is log one same things to different places, err ... ).

  • t1.pl ( launches t2.pl and t3.pl , they all try to log to the same file ) : 
    #!perl 
package MyProjectPackage ;


use strict ; 
use warnings ;
use Win32::Process ;

my $MLIB ;
BEGIN {
    $MLIB = "c:/zlr" ;
}

use lib ( $MLIB . "/lib/" , $MLIB . "/lib/Perl/" )  ;
use Log::Dispatch ;
use Log::Dispatch::File ;

my $dispatcher         = Log::Dispatch->new ;
my $MSOFT         = "c:/zlr/script/test" ;
my $call_hProcess     = ""  ;
my $call_Resultat     = 0 ;
my $i             = 0 ;

$dispatcher->add( Log::Dispatch::File->new( 
                    name => 'MyProjectErrT1',
                    min_level => 'info',
                    filename => "$MSOFT/ErrGeneral.txt" ) );

$dispatcher->log( level => 'info',
                    message => 'Start of log' );
            

$call_Resultat = Win32::Process::Create($call_hProcess,
            "c:/Perl/bin/Perl.exe",
            "perl t2.pl",
            0,
            IDLE_PRIORITY_CLASS,
            "." )  ;

$call_Resultat = Win32::Process::Create($call_hProcess,
            "c:/Perl/bin/Perl.exe",
            "perl t3.pl",
            0,
            IDLE_PRIORITY_CLASS,
            "." )  ;
            
while ( $i < 20 ) { 
        sleep 10 ;
        $dispatcher->log( level => 'info',
                message => "Launcher : $i\n" );
        $i++ ;
    }

  • Here's t2.pl , t3.pl is the same : 
    #!perl 
# Pragmas

package MyProjectPackage ;

use strict ;

my $MLIB ;
BEGIN {
    $MLIB = "c:/zlr" ;

use lib ( $MLIB . "/lib/" , $MLIB . "/lib/Perl/" )  ;

use Log::Dispatch ;
use Log::Dispatch::File ;

my $dispatcher         = Log::Dispatch->new ;
my $MSOFT         = "c:/zlr/script/test" ;
my $call_hProcess     = ""  ;
my $call_Resultat     = 0 ;
my $i             = 0 ;

$dispatcher->add( Log::Dispatch::File->new( 
                    name => 'MyProjectErrT2',
                    min_level => 'info',
                    filename => "$MSOFT/ErrGeneral.txt" ) );

$dispatcher->log( level => 'info',
                    message => 'Start of t2' );
 

while ( $i < 20 ) { 
        sleep 10 ;
        $dispatcher->log( level => 'info',
                message => "t2.pl : $i\n" );
        $i++ ;
    }
