zabbix 监控交换机文本/日志信息

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

cat inspection.py

#!/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
