Thank you David and Rik for your answers,
                                                                I have one more question, I tried executing some perl code from a ajax routine :
something like  :

sub get_stats {
# some perl code goes here 
  ## open a file using perl file open
  ## use dancer logger to output to console
  ## execute shell commands using system call of perl
}

ajax '/killprocess' => sub {
    get_stats;

};

   But it seems that the perl code is not getting executed, I do not have anything shown in my logger (console), 
  am I doing something wrong over here ?

Thank You
\amk

Rik's answer above is the course of action I'd typically recommend
- because even if you just want the array for now, in future you may
well decide you want to provide other information from that call, too
(perhaps be able to return an error message as a key named 'error', or
return the number of results found as a key named 'count', or return
the average of all the values... etc) - so returning a hashref as Rik
illustrates helps with future-proofing, as you could easily add more
information to the response without breaking existing code.
