python nagios监控cloudstack集群的host机状态示例

本文主要是介绍python nagios监控cloudstack集群的host机状态示例，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

cloudstack集群中，host主机有时候状态不正常，从而影响到iaas的业务，于是写了个监控脚本来进行监控，如下：

#cat check_cs_host
#!/usr/bin/python
#desc: this script is to check the status of hosts  in cloudstack
#     can use -h to show usageimport os,sys
import json
from optparse import OptionParserE_OK = 0
E_WARNING = 1
E_CRITICAL = 2
E_UNKNOWN = 3
E_CODE = E_OKparser = 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-' + infoprint performance
sys.exit(E_CODE)

脚本可以添加 -i 或 --ignore参数来忽略一些host的监控告警

如忽略172.16.2.5和172.16.2.6这两台host的状态不正常告警，可以这么写：

check_cs_host --ignore=172.16.2.5,172.16.2.6
