A script to report on the failed checks from sensu. Great for putting in the motd: sensu_report -s my_sensu_server > /etc/motd

parser.add_option("-p", "--port", dest="port",
                  help="sensu server api port", default='4567')
(options, args) = parser.parse_args()

data = json.load(response)
