Azure Resource Graph Explorer::在時間圖表中繪制趨勢線

Question

我正在閱讀這篇關於如何在與 Azure SQL 數據庫消耗相關的時間圖表中繪制趨勢線的文章。

查詢是這樣的：

AzureMetrics
| where TimeGenerated >= ago(90d)
| where Resource == 'MyDB'
| where MetricName == 'full_backup_size_bytes' // in ('full_backup_size_bytes','diff_backup_size_bytes','log_backup_size_bytes')
| make-series SizeBackupDiffTB=max(Maximum/1024/1024/1024/1024) on TimeGenerated in range(ago(90d),now(), 1d)
| extend (RSquare,Slope,Variance,RVariance,Interception,TrendLine)=series_fit_line(SizeBackupDiffTB)
| render timechart

但是 Azure 門戶返回此錯誤：

Please provide below info when asking for support: timestamp = 2022-12-19T09:09:42.5539654Z, correlationId = 9cfa2a61-7cbe-412d-8e21-20b245a0e7da. (Code:BadRequest)

Details:
Query is invalid. Please refer to the documentation for the Azure Resource Graph service and fix the error before retrying. (Code:InvalidQuery)
ParserFailure (Code:ParserFailure)
ParserFailure (Code:ParserFailure)
ParserFailure (Code:ParserFailure)
ParserFailure (Code:ParserFailure)
ParserFailure (Code:ParserFailure)
ParserFailure (Code:ParserFailure)

我認為問題可能出在第二行>=中。

但這意味着什么？

編輯：我認為問題不止一個，因為它不需要make-series和render timechart ：

但是錯誤現在減少了：

Please provide below info when asking for support: timestamp = 2022-12-19T09:37:04.2221903Z, correlationId = 12157f78-2c92-4820-94d6-f088acf1a5a0. (Code:BadRequest)

Details:

ParserFailure (Code:ParserFailure)
ParserFailure (Code:ParserFailure)
ParserFailure (Code:ParserFailure)

這可能是greater-than的 Unicode 沒有正確反映。 您應該在 Log Analytics 中嘗試以下操作：

AzureMetrics
| where TimeGenerated >= ago(90d)
| where Resource == 'MyDB'
| where MetricName == 'full_backup_size_bytes' // in ('full_backup_size_bytes','diff_backup_size_bytes','log_backup_size_bytes')
| make-series SizeBackupDiffTB=max(Maximum/1024/1024/1024/1024) on TimeGenerated in range(ago(90d),now(), 1d)
| extend (RSquare,Slope,Variance,RVariance,Interception,TrendLine)=series_fit_line(SizeBackupDiffTB)
| render timechart
