使用 Nagios NRPE 将参数传递给 Powershell 脚本

  • 772

用于测试的简短 powershell 脚本：

$test = $args[0]
echo "this works"
echo "I transferred $test"
exit 0

nsclient.ini 设置：

# If you want to fill this file with all avalible options run the following command:
#   nscp settings --generate --add-defaults --load-all
# If you want to activate a module and bring in all its options use:
#   nscp settings --activate-module <MODULE NAME> --add-defaults
# For details run: nscp settings --help

  1. Best Answer

    可以在多个级别上允许参数（取决于您希望如何分割“安全性”）。从本质上讲，这意味着您可以在 NRPE 级别和外部脚本级别允许参数（在您的情况下，您可能希望在这两个地方都使用它们）

    你可以在这里找到一些背景细节：http: //docs.nsclient.org/howto/external_scripts.html#arguments

    但是忽略理论来回答你的问题，你需要在两个地方启用允许参数（见下文）：

    [/settings/NRPE/server]
allow arguments=true

[/settings/external scripts]
allow arguments=true

[/settings/external scripts/scripts]
foo=scripts\\foo.bat "argument 1" "argument 2"

    您缺少的是后一个：

    [/settings/external scripts]
allow arguments=true

    因此，添加它可以解决您的问题。

    编辑：添加有关第二个问题的信息。

    power shell 启动的第二个问题（参见这篇文章的评论）与 powershell 奇怪有关，这需要相当复杂的命令行语法：

    [/settings/external scripts/scripts]
test = cmd /c echo scripts\test.ps1 "$ARG1$"; exit($lastexitcode) | powershell.exe -command -

    问题是缺少 - 在命令末尾（上面的正确命令）。
