Use this script for services you don't want BB to alert in red on the first failure. It will become yellow first, and then, after a configurable number of polls, it will go red. Useful with network tests over a noisy link (except when you're responsible for the link ;). Tested only with Linux. http://goo.gl/WZFwNZ
