So in above log structure first I need to fetch all successful child runID(i.e 8286,8287....8296) for parent id 8274.Now for each runID i have to get started producing records time stamp and done with producing records time stamp

I tried below logic but thats messed up.Could you please help me regarding this logic

desired output is below

 
topic,start_time,Endtime
12772_8286_20170317_IN_0,09:54:12.498+0000,09:55:13.027+0000
12772_8287_20170317_IN_0,09:54:13.428+0000,09:55:15.027+0000

Below is my code 

open (MYFILE, '>data.CSV');
$LOGFILE = "worker.log";
open(LOGFILE) or die("Could not open log file.");
$LOGFILE1 = "worker.log";
open(LOGFILE1) or die("Could not open log file.");

$taskid=8274;


foreach $line (<LOGFILE>) 
{
    chomp($line); 
    if ( $line =~ m/$taskid.*child runId vs completion type/)
    {
    
    @Task_id = $line =~ /\{(\d+)-/g;
    
    }    
}


foreach $line (<LOGFILE1>) 
{
    chomp($line); 
    foreach $childid(@Task_id)
    {
    if ( $line =~ m/Started producing records on topic (\d+)_($childid
+)_(\d+)_IN_(\d+)/)
      {
      $envId=$1;
      $timestamp=$3;
      $input=$4;
    my @fields = split / /, $line;
    $data1="$envId\_$childid\_$timestamp\_IN\_$input\,$fields[1]";
    $data2="$envId\_$childid\_$timestamp\_IN\_$input";
    push @data9,$data1 ;
    print "$data1\n";
      }
      
     if ( $line =~ m/Done with producing records on topic (\d+)_($chil

      {
      $envId=$1;

    print "$data3\n";
      }
     
     }
          
}
foreach (@data9) {
 print MYFILE "$_\n";
}    
    
    
close LOGFILE;
close LOGFILE1;
