Python自动巡检H3C交换机实现过程解析

1.通过netmiko模块登录交换机，协议ssh，执行收集信息命令，保存至txt文件

2.过滤txt文件中的内容，保存到excel，使用xlwt模块实现。

3.sendmai发送excel邮件。或者发送给钉钉机器人也可以

4.使用crond定时发送巡检报表。

代码如下

#!/usr/bin/python3 
#H3c交换机
import time
from netmiko import ConnectHandler
now = time.strftime("%Y%m%d",time.localtime(time.time()))
log_time = time.strftime("%Y-%m-%d %H:%M:%S",time.localtime())

ip_list = [
  ['sw-001','192.168.1.1'],
  ['sw-002','192.168.1.2'],
]

SW = {
  'device_type':'hp_comware',
  'username':'admin',
  'ip':'',
  'password':"$password"
}

for ip_item in ip_list:
  SW['ip'] = ip_item[1]
  connect = ConnectHandler(**SW)
  print(log_time + 'Successfully connected to ' + ip_item[0])
  output = connect.send_command('system view')
  iproute = connect.send_command("display ip routing-table")
  version = connect.send_command('dis version')
  fan = connect.send_command('display fan')
  cpu = connect.send_command('display cpu-usage')
  mem = connect.send_command('display memory')
  env = connect.send_command('display environment')
  fo = open('xusj','w')
  fo.write(iproute)
  fo.write(fan)
  fo.write(cpu)
  fo.write(mem)
  fo.write(env)
  fo.close()
