简介
公司有台路由设备，需要每天去核对用户量，查看信息等。为了避免重复的工作量，就通过zabbix来完成这个重复性的工作。
先说下思路，首先要创建一个脚本，能从zabbix-server 或者zabbi-agent 远程到路由/交换机，通过脚本，获取到用户量的数据并存到zabbix-server或者zabbix-agent上，然后在通过zabbix监控获取到想要的信息。
废话不多少 直接上干货
脚本内容
1、通过服务器获取路由的信息
此脚本是通过服务器 ssh 登录到交换机/路由上，然后打印出查询信息，存到服务器的指定路径
我要获取到的是 'dis time all','dis int gig0/1/1','display access-user' 这个三个信息
#!/usr/bin/env python # -*- coding: utf-8 -*- import pexpect import time import sys,os import shutil def ssh_login(Host, Username, Password, Commands): #ssh 登录到交换机/路由 ssh = pexpect.spawn('ssh %s@%s' %(Username, Host)) res = ssh.expect(['password:', 'continue connecting (yes/no)?'], timeout=5) if res == 0: ssh.sendline(Password) elif res == 1: ssh.sendline('yes') ssh.expect('password:') ssh.sendline(Password) ssh.expect([finish,pexpect.TIMEOUT,pexpect.EOF]) for cmd in Commands: print "finish....." ssh.sendline(cmd) for i in range(0,5): ssh.sendline(' ') res = file(filepath,'wb') ssh.logfile_read = res ssh.sendline('quit') ssh.read() ssh.close() res.close() def filename_change(filepath): localtime=time.strftime('%Y%m%d%H%M',time.localtime(time.time())) dirtime=time.strftime('%Y%m',time.localtime(time.time())) filename=os.path.split(filepath) filedir=filename[0]+'/'+dirtime isExists=os.path.exists(filedir) if not isExists: os.makedirs(filedir) filenewname=filename[1].split('.') shutil.move(filepath, filedir) os.chdir(filedir) #os.rename(filename[1],filenewname[0]+'_'+localtime+'.'+filenewname[1]) if __name__=='__main__': Host = '192.168.4.3' Username = 'lenovoxj' Password = 'Lenovo@123' Commands = ['dis time all','dis int gig0/1/1','display access-user'] finish = '<HZ-YD-RT-LNS-1>' filepath = '/home/data/xunjian/log/lns1hz.txt' ssh_login(Host, Username, Password, Commands) #filename_change(filepath)
运行脚本，查看获取得到的信息是否正确

2、zabbix获取服务器上的信息
我们这个脚本是配置到zabbix server 上的，所以吧监控项也配置到zabbix server上
名称：随意填写
类型：客户端
键值：vfs.file.contents[/home/data/xunjian/log/lns1hz]
#一定要是 [绝对路径]
信息类型：文本
添加监控项刷新等待
