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

import re

from pprint import pprint

#甯歌?鍘傚?鏁伴€氳?澶嘙IB鍊?

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':{

}

}

#绔?彛鐘舵€佽浆鎹?

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("%st%st%s"%(i,host.ljust(30),portStatus(status).ljust(20)))

print(''.ljust(50,'#'))

运行结果：

root@ubuntn12:/tmp# python snmpwalk.py

10.221.98.2 InLoopBack0 up

10.221.98.2 NULL0 up

10.221.98.2 GigabitEthernet0/0/0 down
