返回 BadRequest 的 New-AzScheduledQueryRule

Question

我想根据查询使用 PowerShell 创建日志警报。我按照https://docs.microsoft.com/en-us/azure/azure-monitor/platform/alerts-log#managing-log-alerts-using-powershell 下的说明进行了修改，如下所示：

$source = New-AzScheduledQueryRuleSource -Query "AzureActivity | where Category == 'Policy' and Level != 'Informational' | extend p=todynamic(Properties) | extend policies=todynamic(tostring(p.policies)) | mvexpand policy = policies | where p.isComplianceCheck == 'False'" -DataSourceId "$Workspace.ResourceId"

$schedule = New-AzScheduledQueryRuleSchedule -FrequencyInMinutes 5 -TimeWindowInMinutes 5

$metricTrigger = New-AzScheduledQueryRuleLogMetricTrigger -ThresholdOperator "GreaterThan" -Threshold 0 -MetricTriggerType "Consecutive" -MetricColumn "_ResourceId"

$triggerCondition = New-AzScheduledQueryRuleTriggerCondition -ThresholdOperator "GreaterThan" -Threshold 0 -MetricTrigger $metricTrigger

$aznsActionGroup = New-AzScheduledQueryRuleAznsActionGroup -ActionGroup "$actionGroup.Id" -EmailSubject "New Resource Group with missing tags" -CustomWebhookPayload "{ `"alert`":`"#alertrulename`", `"IncludeSearchResults`":true }"

$alertingAction = New-AzScheduledQueryRuleAlertingAction -AznsAction $aznsActionGroup -Severity "3" -Trigger $triggerCondition

上述命令成功，但是当我运行以下命令来创建规则时：

New-AzScheduledQueryRule -ResourceGroupName $ResourceGroup -Location $Location -Action $alertingAction -Enabled $true -Description "Alert description" -Schedule $schedule -Source $source -Name "Alert Name"

我收到了一个错误请求：

PS /home/nicolas> New-AzScheduledQueryRule -ResourceGroupName $ResourceGroup -Location $Location -Action $alertingAction -Enabled $true -Description "Alert description" -Schedule $schedule -Source$source -Name "Alert Name"

我找不到原因。

你有什么想法吗？

bad request 错误太板了，你可以使用Fiddler 来捕捉详细的错误信息。并为$actionGroup.Id 和$Workspace.ResourceId 指定值（工作区是您之前创建的）。我参考了这个article，这是我的代码：

$source = New-AzScheduledQueryRuleSource -Query 'Heartbeat | summarize AggregatedValue = count() by bin(TimeGenerated, 5m), _ResourceId' -DataSourceId "/subscriptions/xxxxxxx/resourceGroups/xxxxxxx/providers/microsoft.OperationalInsights/workspaces/yourWorkspaceName"

$schedule = New-AzScheduledQueryRuleSchedule -FrequencyInMinutes 15 -TimeWindowInMinutes 30

$metricTrigger = New-AzScheduledQueryRuleLogMetricTrigger -ThresholdOperator "GreaterThan" -Threshold 2 -MetricTriggerType "Consecutive" -MetricColumn "_ResourceId"

$triggerCondition = New-AzScheduledQueryRuleTriggerCondition -ThresholdOperator "LessThan" -Threshold 5 -MetricTrigger $metricTrigger

$aznsActionGroup = New-AzScheduledQueryRuleAznsActionGroup -ActionGroup "/subscriptions/xxxxxxx/resourceGroups/xxxxxxx/providers/microsoft.insights/actiongroups/yourAGName" -EmailSubject "Custom email subject" -CustomWebhookPayload "{ `"alert`":`"#alertrulename`", `"IncludeSearchResults`":true }"

$alertingAction = New-AzScheduledQueryRuleAlertingAction -AznsAction $aznsActionGroup -Severity "3" -Trigger $triggerCondition


New-AzScheduledQueryRule -ResourceGroupName "xxxxxxx" -Location "Central US" -Action $alertingAction -Enabled $true -Description "Alert description" -Schedule $schedule -Source $source -Name "Alert Name"

这是输出：
