nagios监控cloudstack的主机的状态

cloudstack 中的host主机因为一些原因导致状态不为up状态，希望nagios通过cloudmonkey来监控这个状态，如下：

#!/usr/bin/python
#desc: this script is to check the status of hosts  in cloudstack
#     can use -h to show usage
 
import os,sys
import json
from optparse import OptionParser
 
E_OK = 0
E_WARNING = 1
E_CRITICAL = 2
E_UNKNOWN = 3
E_CODE = E_OK
 
parser = OptionParser()
parser.add_option("-i","--ignore",dest="ignore",
          help="ipaddress that ignore to check ")
(options,args) = parser.parse_args()
 
 
comm = '/usr/bin/cloudmonkey -d json list hosts type=Routing filter=ipaddress,state'
performance = ''
info = ''
 
host_info = os.popen(comm).read()
host_json = json.loads(host_info)['host']
if options.ignore:
    for item in host_json:
        if not item['ipaddress'] in options.ignore and item['state'] != 'Up':
            info += '%s : %s' % (item['ipaddress'],item['state'])    
            E_CODE = E_CRITICAL
else:
    for item in host_json:
                if item['state'] != 'Up':
                        info += '%s:%s; ' % (item['ipaddress'],item['state'])
                        E_CODE = E_CRITICAL  
 
if E_CODE == E_OK :
    performance += 'OK'
elif E_CODE == E_WARNING:
        performance = 'WARNING-' + info
elif E_CODE == E_CRITICAL:
    performance = 'CRITICAL-' + info
else:
    performance = 'UNKNOWN-' + info
 
print performance
sys.exit(E_CODE)
