我正在读这篇文章article了解如何在与 Azure SQL 数据库消耗相关的时间图表中绘制趋势线。
查询是这样的:
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 门户返回此错误:
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)
我认为问题可能出现在第二行>=。
但这意味着什么？
编辑:我认为存在不止一个问题，因为它不需要 make-series 和 render timechart:
但是错误现在减少了:
Please provide below info when asking for support: timestamp = 2022-12-19T09:37:04.2221903Z, correlationId = 12157f78-2c92-4820-94d6-f088acf1a5a0. (Code:BadRequest)

最佳答案
这可能是 greater-than 的 Unicode这没有得到正确反射(reflect)。您应该在 Log Analytics 中尝试以下操作:
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
