Nagios NRPEを使用してPowershellスクリプトに引数を渡す
テスト用の短いPowerShellスクリプト：
$test = $args[0]
echo "this works"
echo "I transferred $test"
exit 0
nsclient.ini設定：
# 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

何が欠けていますか？
引数は複数のレベルで許可できます（「セキュリティ」をどのようにスライスするかによって異なります）。本質的に、これは、NRPEレベルと外部スクリプトレベルで引数を許可できることを意味します（そして、あなたの場合、おそらく両方の場所でそれらが必要です）
背景の詳細については、こちらをご覧ください。 http://docs.nsclient.org/howto/external_scripts.html#arguments
しかし、あなたの質問に答えるための理論を無視すると、[〜＃〜] two [〜＃〜]の場所で許可引数を有効にする必要があります（以下を参照） ：
[/settings/NRPE/server]
allow arguments=true
[/settings/external scripts]
allow arguments=true
[/settings/external scripts/scripts]
foo=scripts\\foo.bat "argument 1" "argument 2"
あなたが欠けているのは後者です：
[/settings/external scripts]
allow arguments=true
したがって、それを追加すると問題が解決します。
編集：2番目の問題に関する情報を追加します。
Power Shellの起動に関する2番目の問題（この投稿へのコメントを参照）は、かなり複雑なコマンドライン構文を必要とするPowerShellの奇妙さに関連していました。
[/settings/external scripts/scripts]
test = cmd /c echo scripts\test.ps1 "$ARG1$"; exit($lastexitcode) | powershell.exe -command -
問題は、コマンドの最後に-がないことでした（上記の正しいコマンド）。
