centos7写一个监控系统的shell,要求如下 cpu使用率超过80%(Shell变量单独配置)并且持续60秒钟(Shell变量单独配置)以上使用Curl post json方式调用http://aaa.com接口,传入以下JSON信息 服务器ip(Shell变量单独配置)+当前CPU使用率+持续时间+CPU占用率最高的前3个进程名字以及文件路径 内存使用率超过70%(Shell变量单独配置)并且持续70秒钟(Shell变量单独配置)以上使用Curl post json方式调用http://aaa.com接口,传入以下JSON信息 服务器ip(Shell变量单独配置)+当前内存使用率+持续时间+内存占用率最高的前3个进程名字以及文件路径 硬盘使用率超过90%(Shell变量单独配置)并且持续90秒钟(Shell变量单独配置)以上使用Curl post json方式调用http://aaa.com接口,传入以下JSON信息 服务器ip(Shell变量单独配置)+当前硬盘使用率+持续时间+磁盘占用最大的3个文件以及大小(以KB、GB、TB等为单位,精确到1位小数)和文件路径 脚本持续监控,每隔N秒(Shell变量单独配置)执行一次,要求直接给出最完美的shell代码，无需任何解释
