You might want to look into Rex, and specifically Rex HowTo: Listing all running processes. 
use Rex::Commands::Process;

user "my-user";
password "my-password";
pass_auth;

group myserver => "mywebserver", "mymailserver", "myfileserver";

desc "List all running processes";
task "ps", group => "myserver", sub {

   for my $process ( ps() ) {
      say "command: " . $process->{"command"};
      say "pid    : " . $process->{"pid"};
      say "user   : " . $process->{"user"};
   }

};
