Powershell
使用 Nagios NRPE 將參數傳遞給 Powershell 腳本
用於測試的簡短 powershell 腳本:
$test = $args[0] echo "this works" echo "I transferred $test" exit 0
nsclient.ini 設置:
# 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 ; Undocumented section [/modules] ; CheckDisk - CheckDisk can check various file and disk related things. The current version has commands to check Size of hard drives and directories. CheckDisk = 1 ; Event log Checker. - Check for errors and warnings in the event log. This is only supported through NRPE so if you plan to use only NSClient this wont help you at all.

This is also only supported through NRPE.

和錯誤資訊:
$ /usr/local/nagios/libexec/check_nrpe -H 10.11.11.101 -c test -a blablabla 返回程式碼:3(未知)輸出:參數不允許
我錯過了什麼?
可以在多個級別上允許參數(取決於您希望如何分割“安全性”)。從本質上講,這意味著您可以在 NRPE 級別以及外部腳本級別允許參數(在您的情況下,您可能希望在這兩個地方都使用它們)
你可以在這裡找到一些背景細節:http: //docs.nsclient.org/howto/external_scripts.html#arguments
但是忽略理論來回答你的問題,你需要在兩個地方啟用允許參數(見下文):
[/settings/NRPE/server] allow arguments=true [/settings/external scripts] allow arguments=true [/settings/external scripts/scripts] foo=scripts\\foo.bat "argument 1" "argument 2"
您缺少的是後一個:
[/settings/external scripts] allow arguments=true
因此,添加它可以解決您的問題。
**編輯:**添加有關第二個問題的資訊。
power shell 啟動的第二個問題(參見這篇文章的評論)與 powershell 奇怪有關,這需要相當複雜的命令行語法:
[/settings/external scripts/scripts] test = cmd /c echo scripts\test.ps1 "$ARG1$"; exit($lastexitcode) | powershell.exe -command -
問題是缺少 - 在命令末尾(上面的正確命令)。
