Azure诊断设置：PowerShell输出Event Hub与Log Analytics Workspace值为空排查求助

在Azure门户中已为资源诊断设置配置Event Hub和Log Analytics Workspace值，但执行以下PowerShell脚本获取诊断设置时，这两个字段输出为空值：

$resources = Get-AzResource

# Iterate through each resource and get diagnostic settings
foreach ($resource in $resources) {
    $resourceName = $resource.Name
    $resourceGroup = $resource.ResourceGroupName
    $resourceType = $resource.ResourceType

    # Get diagnostic settings for the resource
    $diagnosticSettings = Get-AzDiagnosticSetting -ResourceId $resource.Id

    # Print the diagnostic settings
    Write-Host "Resource: $resourceName ($resourceType) in $resourceGroup"
    foreach ($setting in $diagnosticSettings) {
        Write-Host "  - Diagnostic Setting Name: $($setting.Name)"
        Write-Host "  - Event Hub: $($setting.Eventhub)"
        Write-Host "  - Log Analytics workspace: $($setting.LogAnalyticsworkspace)"

}}

问题出在你引用的属性名称错误，Get-AzDiagnosticSetting返回的对象中，Event Hub和Log Analytics Workspace对应的属性名并非脚本里的Eventhub和LogAnalyticsworkspace。

正确的属性说明： #

• Event Hub相关：
  • EventHubName：配置的Event Hub名称
  • EventHubAuthorizationRuleId：Event Hub的授权规则ID
• Log Analytics Workspace：
  • WorkspaceId：目标工作区的资源ID

修正后的脚本： #

$resources = Get-AzResource

# Iterate through each resource and get diagnostic settings
foreach ($resource in $resources) {
    $resourceName = $resource.Name
    $resourceGroup = $resource.ResourceGroupName
    $resourceType = $resource.ResourceType

    # Get diagnostic settings for the resource
    $diagnosticSettings = Get-AzDiagnosticSetting -ResourceId $resource.Id

    # Print the diagnostic settings
    Write-Host "Resource: $resourceName ($resourceType) in $resourceGroup"
    foreach ($setting in $diagnosticSettings) {
        Write-Host "  - Diagnostic Setting Name: $($setting.Name)"
        Write-Host "  - Event Hub Name: $($setting.EventHubName)"
        Write-Host "  - Event Hub Auth Rule ID: $($setting.EventHubAuthorizationRuleId)"
        Write-Host "  - Log Analytics Workspace ID: $($setting.WorkspaceId)"
    }
}

你也可以通过$diagnosticSettings | Get-Member命令查看返回对象的所有属性，直接确认字段名称，避免类似的属性名拼写或匹配错误。
