Zabbix Agent 无法通过远程脚本发现服务

Question

我正在尝试创建依赖于 PowerShell 脚本的模板，该脚本枚举远程 Windows 服务器上的服务。然后它应该为每个服务创建一个默认为禁用的项目，我可以在其中启用我想要监控的项目。我部署了以下脚本、配置更改和模板，但是没有任何项目填充。

################################################################################
# get_services.ps1
#
################################################################################

$services = Get-Service | select name

Write-Host "{"
Write-Host " `"data`":[`n"
ForEach($s in $services) {
    $line= "{ `"{#SERVICE}`" : `"" + $s.Name + "`" }"
    Write-Host $line
}
Write-Host
Write-Host " ]"
Write-Host "}"

---

################################################################################
# get_servicestate.ps1
#
################################################################################

Param ([String] $name = 0)
$service = Get-Service -Name $name
Write-Host $service.Status

### Option: UserParameter
#   User-defined parameter to monitor. There can be several user-defined parameters.
#   Format: UserParameter=<key>,<shell command>
#
# Mandatory: no
# Default:
# UserParameter=
UserParameter=org.service.discovery,powershell -NoProfile -ExecutionPolicy Bypass -File "S:\Zabbix\templates\Zabbix_Services_monitoring\get_services.ps1"
UserParameter=org.service.state[*],powershell -NoProfile -ExecutionPolicy Bypass -File S:\Zabbix\templates\Zabbix_Services_monitoring\get_servicestate.ps1 "$1"

Answer 1

get_services.ps1 未生成有效的 JSON。字典值需要用逗号分隔，但数组中的最后一项除外。更正后的 .ps1 文件如下：

################################################################################
# get_services.ps1
#
################################################################################

$services = Get-Service | select name
$idx = 1

Write-Host "{"
Write-Host " `"data`":[`n"
ForEach($s in $services) {

    if ($idx -lt $services.count)
    {
        $line= "{ `"{#SERVICE}`" : `"" + $s.Name + "`" },"
        write-host $line
    }
    elseif ($idx -ge $services.count)
    {
        $line= "{ `"{#SERVICE}`" : `"" + $s.Name + "`" }"
        write-host $line
    }

    $idx++;

}
Write-Host
Write-Host " ]"
Write-Host "}"
