使用 Nagios 监控文件夹中的文件

我开始使用 nagios 来监控我们的一些系统，我想知道是否有人遇到过让它监控文件目录的方法。

我想查看一个目录并说其中有 x 个超​​过 x 分钟的文件，所以警告我。

干杯

我找到了一个插件（不记得在哪里），它似乎在生产中运行良好。

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

如果目录包含一个或多个文件，则会发出警告；如果包含两个或两个以上文件，则会发出严重警告。该插件使用find，因此用 修改它以-mtime xxx仅检查超过一定年限的文件将是微不足道的。

插件本身是：

# 3 Unknown  Invalid command line arguments or could not determine directory size
#
# Example: check_numoffiles -d . -w 1000 -c 1400
