1、在上⼀篇⽂章⾥给⼤家介绍，这篇⽂章介绍linux服务巡检脚本⽣成html报告。
2、脚本依然是简单脚本语句的堆积，⽅便⼤家⼆次编辑使⽤。
3、项⽬已经上传到我的github上
项⽬地址：
⼆、注意事项与报告部分截图
⼀定注意阅读git上的README.md说明，避免部分信息⽆法正常显⽰ 三、README.md
1、使⽤root⽤户执⾏
2、使⽤说明
1)、脚本中 ifconfig、mpstat、iostat命令有依赖，需要安装相关依赖包yum -y install bc sysstat net-tools
2)、执⾏完巡检之后，将在脚本所在的路径下⽣成html巡检结果报告，如下192.168.31.102os_linux_summary.html
3)、巡检项信息如下（其他统计项可根据实际需要⾃⾏添加）
1)、系统基本信息
2)、cpu信息
3)、ip⽹络信息
4)、cpu使⽤率
5)、连接数信息
6)、系统限制信息
7)、内存使⽤信息
8)、磁盘使⽤信息
9)、⽹络流量情况/系统资源变化网站生成系统
10)、cpu消耗情况前10排⾏
11)、cpu消耗按内存情况前10排⾏
12)、磁盘io情况
14)、系统定时任务脚本内容
四、脚本内容
