一、
一般项目基本完成的时候，后期运维工作的重点就是及时的，合理的频率巡检了，巡检的目的主要是及时发现各种各样的问题
那么，自己编写shell脚本是大部分人的第一选择，这里有个比较麻烦的地方，shell脚本可能巡检的指标不够全面，以及shell脚本难以编写的问题
🆗，这里我推荐大家使用xsos这个软件来简化巡检的工作，很多巡检工作可以使用此工具代替了
二、
xsos的下载地址
https://codeload.github.com/ryran/xsos/tar.gz/refs/tags/v0.7.33
下载完毕后，解压，将xsos这个可执行文件移动到/usr/local/bin/目录下并赋予执行权限即可使用，此软件无需任何依赖，无需任何动态链接库，可以直接使用，非常nice的，主要因为它是其实是一个写的非常长的shell脚本！！！！！！！！！！！！！！！！（有4000多行）
[root@centos7 xsos-0.7.33]# ldd /usr/local/bin/xsos not a dynamic executable
[root@centos7 xsos-0.7.33]# file /usr/local/bin/xsos
/usr/local/bin/xsos: Bourne-Again shell script, UTF-8 Unicode text executable, with very long lines
三、
此软件下载只能在github，其它地方没有发现，需要指出的是，此软件和sosreport这个软件比较类似，是可以基于sosreport命令运行所产生的文件来工作的，当然，xsos单独也是可以工作的
单独运行此软件：
1、获取系统的信息和内存信息
xsos --os --mem
输出如下：

总之，以上参数可以自由搭配组合得出自己喜欢的一个输出内容，从而得到一个自己所期望的巡检结果
该工具还是非常非常nice的哦~~~
