Hi Monks I have a Perl script that counts the total queues from URL. Script is working fine and developer has mentioned that i can put specific queue name and limit. If queue goes above the limit, it warn me.......now i am not Perl guy and not able to understand this script. I dont know what to change to get the result(specific queue).
