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
代码如下:
#/usr/bin/python#coding:utf-8
import os,sysimport refrom 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’#鎵ц绯荤粺鍛戒护snmpwalk璋冪敤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
代码如下:
