使用New-AzScheduledQueryRuleConditionObject创建警报规则遇参数错误

执行PowerShell创建Azure计划查询警报规则时，触发以下错误：

##[error]The term '-Operator' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.

微软官方文档明确New-AzScheduledQueryRuleConditionObject支持-Operator参数，问题代码示例如下：

$QueryRuleQuery = "let MinTime = ago(5m);
AzureMetrics
| where TimeGenerated < MinTime
    and MetricName == `"storage_percent`"
    and Maximum >= $($Threshold)
    and (ResourceId has `"ELASTICPOOLS`" or ResourceId has `"DATABASES`")
| project ResourceGroup, Resource, MetricName, Maximum,ResourceId
| distinct ResourceGroup, Resource, MetricName, Maximum,ResourceId
"
$QueryRuleScope = "/subscriptions/$($SubscriptionId)/resourcegroups/$($REDACTED.ToLower())-$($Environment.ToLower())-redacted/providers/microsoft.operationalinsights/workspaces/$($REDACTED.ToLower())-$($RegionCode.ToLower())-$($EnvironmentShort.ToLower())-redacted"
$QueryRuleCondition = New-AzScheduledQueryRuleConditionObject `
    -Query $QueryRuleQuery `
    -TimeAggregation 'Count' `
    -ResourceIdColumn 'Resource' `
    -Operator 'GreaterThanOrEqual' `
    -Threshold 10 `
    -FailingPeriodNumberOfEvaluationPeriod 1 `
    -FailingPeriodMinFailingPeriodsToAlert 1

New-AzScheduledQueryRule `
    -Name $QueryRuleName `
    -ResourceGroupName $ResourceGroupName `
    -Location $RegionCodeDatacenter `
    -ActionGroupResourceId "/subscriptions/$($SubscriptionId)/resourceGroups/$($REDACTED.ToLower())-$($Environment.ToLower())-redacted/providers/microsoft.insights/actionGroups/$($REDACTED.ToLower())-$($RegionCode.ToLower())-$($EnvironmentShort.ToLower())-redacted"
    -Description "This will trigger when an Elastic Pool or Database reaches $($Threshold) percent of maximum size"
    -DisplayName $QueryRuleName `
    -Scope $QueryRuleScope `
    -Severity $QueryRuleSeverityInt `
    -WindowSize 'P1D' `
    -EvaluationFrequency 'P1D' `
    -CriterionAllOf $QueryRuleCondition

解决步骤： #

• 升级Az.Monitor模块：旧版本Az.Monitor可能未引入-Operator参数，运行以下命令更新模块：

  Update-Module -Name Az.Monitor -Force
  

  可通过Get-Module -ListAvailable Az.Monitor查看当前版本。

• 修复代码换行语法错误：New-AzScheduledQueryRule中-ActionGroupResourceId行末尾缺失反引号（`），导致后续参数被解析为独立命令，引发连锁错误。修正后该行应为：

  -ActionGroupResourceId "/subscriptions/$($SubscriptionId)/resourceGroups/$($REDACTED.ToLower())-$($Environment.ToLower())-redacted/providers/microsoft.insights/actionGroups/$($REDACTED.ToLower())-$($RegionCode.ToLower())-$($EnvironmentShort.ToLower())-redacted" `
  

• 确认PowerShell环境兼容性：在DevOps流水线中，使用PowerShell Core 7.x版本执行脚本，避免旧版PowerShell的兼容性问题。
