本文实例讲述了Python实现数通设备端口使用情况监控的方法。分享给大家供大家参考。具体如下：

最近因工作需要，上面要求，每天需上报运维的几百数通设备端口使用情况【】，虽然有现成网管监控工具监控设备状态，但做报表，有点不方便，特写了个小脚本。上传的，为半成品可用程序

注：测试运行于ubuntn，需安装snmpwalk工具，

目标数通设备，需做好相关snmp配置

#/usr/bin/python

MIB = {
 \'public\':{
  \'ports\':{
   \'string\':\'.1.3.6.1.2.1.2.2.1.2\',
   \'status\':\'.1.3.6.1.2.1.2.2.1.8\', #2 down
  }
 },
 \'huawei\':{

 \'cisco\':{

}

def portStatus(_s):
 if int(_s)==2:
  return \'down\'
 elif int(_s)==1:
  return \'up\'
 else:
  return \'none\'

def snmpwalk(host,publicKey,iso):
 return [i.strip() for i in os.popen(\'/usr/bin/snmpwalk -c %s -v 2c %s %s\'%(publicKey,host,iso)).readlines()]
def getPorts(_ip,_public,option):
 if option == \'ports\':
  postsString = (j.split(\'=\')[1].split(\':\')[1].replace(\'\"\',\'\').strip() for j in snmpwalk(_ip,_public,MIB[\'public\'][\'ports\'][\'string\']))
  postsStatus = (int(j.split(\'=\')[1].split(\':\')[1].strip()) for j in snmpwalk(_ip,_public,MIB[\'public\'][\'ports\'][\'status\']))
  return zip(postsString,postsStatus)
 else:
  print(\'on this commmnad\')
publicKey = \'hi\' #sunmp public key
HOSTS={
 \'10.221.98.2\':{\'type\':\'switch\',\'origin\':\'quidway\',\'public\':publicKey},
 \'10.221.98.3\':{\'type\':\'switch\',\'origin\':\'quidway\',\'public\':publicKey},
 \'10.221.97.108\':{\'type\':\'firewall\',\'origin\':\'h3c\',\'public\':publicKey},
 \'10.231.98.233\':{\'type\':\'switch\',\'origin\':\'cisco\',\'public\':publicKey},
}
if __name__ == \'__main__\':
 for i in HOSTS.keys():
  for host,status in getPorts(i,HOSTS[i][\'public\'],\'ports\'):
   print(\"%s\\t%s\\t%s\"%(i,host.ljust(30),portStatus(status).ljust(20)))
  print(\'\'.ljust(50,\'#\'))

运行结果：
