I'm glad that you found a solution. I had been working on this before you made your post. I thought that I'd post it just in case it gives you some ideas.

I used Parallel::Runner to run 5 scrapers

#!/usr/bin/perl

use strict;
use warnings;
use Parallel::Runner;

open STDOUT, '>', 'ssh.log'
        or die "Couldn't open ssh.log: $!\n";

my $runner = Parallel::Runner->new(5);
$runner->run( sub { system("perl scraper1.pl") });
$runner->run( sub { system("perl scraper2.pl") });
$runner->run( sub { system("perl scraper3.pl") });
$runner->run( sub { system("perl scraper4.pl") });
$runner->run( sub { system("perl scraper5.pl") });
$runner->finish;

Then I used this to check the log

#!/usr/bin/perl

use strict;
use warnings;
use Net::SSH::Perl;

connectToServer();

sub connectToServer {

    my $host     = 'remote_server';
    my $username = 'user';
    my $password = 'password';
    my $cmd      = 'cat /path/to/ssh.log';

    my $ssh = Net::SSH::Perl->new(
        $host,
        protocol => '2,1',
        debug    => 1,
    );
    $ssh->login( $username, $password );
    
    my ( $stdout, $stderr, $exit ) = $ssh->cmd($cmd);
    print $stdout, "\n";
}
