使用Nagios监视文件夹中的文件

我发现这个插件（不记得在哪里），这似乎在生产中很好地工作。

define command{ command_name check_numfiles command_line $USER1$/check_numoffiles.sh $ARG1$ } 

和

 check_command check_numfiles!-d /var/spool/sms/failed -w 1 -c 2 

如果目录中包含一个或多个文件，则会发出警告，如果两个或多个文件严重， 该插件使用find ，因此使用-mtime xxx进行修改以仅检查超过特定年龄的文件将是微不足道的。

插件本身是：
