Python实现数通设备端口使用情况监控实例

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。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&＃63;
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&＃63;
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：
