python实现数通设备端口监控示例
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。
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

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
