Use Jenkiz to monitor Cron Job with hudson_wrapper

The easest way to use Jenkinz to monitor cron job is use hudson_wrapper as show below:

1. Put hudson_wrapper.sh, from https://github.com/joemiller/hudson_wrapper, on each server, and update the /etc/crontab as below:
     0 * * * * root /path/hudson_wrapper.sh Jenkinz_URL name command
