Re^2: Creating a comprehensive log file

[juo]

I created a customized log file which contains information as I want it to get into the log file. Some example can be seen below.

WriteLog("PROJECTCONTROL","INFO",'ID1252',"Project Name is \<$project_
+name\>");
WriteLog("PROJECTCONTROL","INFO",'ID1250',"Datasource of this job was 
+\<$datasources\>");


sub WriteLog
{
 my ($script,$type,$id,$log) = @_;
 $logfile = $job_path.'/user/LogFile.txt';
 my $logdate = $today;
 my $loguser = $USERNAME;
 open (LOG, ">>$logfile") || die "File does not exist\n";
  print LOG "$script $type $id $loguser $logdate   $log\n";
  close (LOG);
}

This works very nice and I can now from the log file know what exactly is happening and where something is in the process and which script is running and if something failed upto which point something had ran fine. However in case something fails what I will not get into this file is the failure message which will be returned by Perl, or an application or anything else, which is mostly returned to the STDOUT screen. So I see they are some modules maybe available to do this but I would like to stick to my customized log file and just would like to add the warning and errors which would be provided by Perl itself to it. I don't know if this is possible in an easy way.
