使用Ruby編寫(xiě)nagios監(jiān)控腳本監(jiān)控Windows主機(jī)

以下通過(guò)一個(gè)自己寫(xiě)的實(shí)例來(lái)說(shuō)明：

監(jiān)控目的是判斷指定的文件是否存，如不存在就報(bào)警，而傳入的參數(shù)是指定文件的根路徑，也可以改成全路徑，例子只是為了說(shuō)明ruby腳本在nagios中的部署方法，而并不是為了說(shuō)明使用ruby來(lái)判斷文件是否存在有多便利。

# To use in nagios for NSClient++:
#   - Put the script into the %SCRIPT% directory
# modifications in NSC.ini:
# =========================
#
# in [modules]:
# CheckExternalScripts.dll
#
# in [NRPE]:
# allow_arguments=1
# allow_nasty_meta_chars=1
# allowed_hosts=x.x.x.x
#
# in [External Script]:
# allow_arguments=1
# allow_nasty_meta_chars=1

# in [Script Wrappings]:
# rb=ruby.exe scripts\%SCRIPT% %ARGS%

# nagios usage:
