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
    import re
    from pprint import pprint
    #甯歌�����伴�璁惧�MIB�?
    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���舵�杞��#63;
    def portStatus(_s):
     if int(_s)==2:
      return 'down'
     elif int(_s)==1:
      return 'up'
     else:
      return 'none'
    #�ц�绯荤��戒护snmpwalk璋��
    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：

root@ubuntn12:/tmp# python snmpwalk.py

10.221.98.2 NULL0 up
10.221.98.2 GigabitEthernet0/0/0 down
