1、在上一篇文章里给大家介绍oracle自动巡检脚本生成html报告，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：oswatch.git
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-tools2)、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
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
13)、系统定时任务列表
14)、系统定时任务脚本内容
四、脚本内容
