python实现数通设备端口使用情况监控实例

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
#coding:utf-8
import os,sys

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:
