Help creating SNMP Check

What is the next step`?

This is the check, how do i get this to be a service?

def inventory_switch_cpu1(info):
   perc5 = info[0][0].strip().split("(")[1].split(")")[0].replace("%","")
   print perc5
   return []

def check_switch_cpu1(item, _no_params, info):
   if perc5 < 70:
      return 0, "OK - CPU% is " + perc5
   else:
      return (3, "UNKNOWN - not yet implemented")

check_info["switch_cpu1"] = {
    "check_function"        : check_switch_cpu1,
    "inventory_function"    : inventory_switch_cpu1,
    'service_description': 'CPU utilization',
    "snmp_info"             : ( ".1.3.6.1.4.1.4526.11.1.1.4", ["9"] ),
    'includes': ['cpu_util.include'],
    'group': 'cpu_utilization',
}
