前言：
Linux服务器是系统重要的业务运行平台，对服务器进行巡检能够及时发现服务器的隐患，以便于改善和优化服务器的性能；观察服务器的运行状况，及时对设备进行调整，保证服务器的24小时不间断的工作；以及采集网内服务器信息。在此，为了便于运维人员顺利的完成服务器巡检工作，小编写了此文档，希望对Linux服务器的巡检工作起到指导、帮助的作用。
一、巡检项目
1、服务器硬件检查
2.操作系统检查
3.性能检查
4.安全检查
二、收集的脚本
巡检项信息如下（也可自行添加收集信息的模块）：
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
脚本使用前注意事项
需要使用root用户执行 下载脚本：
- 使用说明 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
- 执行chmod 777 oswatch.sh；然后直接sh oswatch.sh执行；
- 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：
脚本内容如下：
代码语言：javascript复制#!/bin/bash
ipaddress=`ip a|grep "global"|awk '{print $2}' |awk -F/ '{print $1}'`
file_output=${ipaddress}'_os_linux_summary.html'
