在你拥有多台服务器，并且需要时刻关注服务器运行是否稳定正常的时候，就需要一个服务器状态监控。这里可以用iis7服务器监控工具实时监控，IIS7服务器监控工具，操作简单，删除系统缓存，重启服务器，修改服务器账号密码，修复服务器复制功能等，也可以一键开启关闭MYSQL和503错误的监控，省去了繁琐的操作步骤，一键完成。也可以直接修改远程端口范围，省去繁琐步骤。
于是乎使用脚本定时发送服务器状态到统计接口的需求就应运而生。

# 检查并置入定时器
function check_cron(){

if [[ "$RET" != "" ]];then #发现了任务

使用方法
wget http://monitor.domain.com/Public/shell/monitor.sh
sh monitor.sh
以上脚本如果在个别服务器中运行不正常，需要自己调整获取参数。
