基于VBS实现SecureCRT的命令自动输入和自动记录
1.功能概述
目前在从事运维工作,因为看到网络设备巡检工作比较重复单调,于是萌生了写脚本将巡检命令自动输入的念头。虽然目前运维有更多高级的方法,可是SecureCRT界面简单,使用方便,仍然有其用武之地。目前网上资料并不多,在实现的过程中也遇到不少困难,因为决定写一篇文章分享一下自己的经验,给有需要的小白们一些参考。
笔者工作的场景主要使用的网络设备有Juniper SRX3600,H3C S12518,F5-2400,因此为这些设备实现了自动巡检,主要检查的项目有:
Juniper SRX 3600:
(1)机箱告警(chassis alarms)
(2)系统告警(system alarms)
(3)系统启动时间(system uptime)
(4)路由引擎(chassis routing-engine)
(5)集群状态(chassis cluster status)
(6)板卡状态(chassis fpc pic-status)
(7)电源状态(chassis environment pem)
(8)60sCPU利用率(security monitoring performance spu)
(9)CPU利用率、内存利用率、Flow session占用率(security monitoring)
S12518:
(1)CPU利用率(cpu-usage)
(2)内存利用率(memory)
(3)启动时间(version)
(4)板卡状态(device)
(5)温度(environment)
(6)告警信息(alarm)
(7)风扇状态(fan)
(8)同步情况(ntp-service status)
(9)IRF链路状态(irf link)
F5-2400:
(1)连接情况(sys performance connection)
(2)系统情况(sys performance system)
(3)吞吐量情况(sys performance throughput)

其中equipmentInfo文件格式如下,为IP 用户名 密码 设备类型,各字段之间以空格分隔。设定好设备信息文件路径和log文件路径之后,运行脚本,就可以得到各个设备巡检结果的log了。
