如需在 Azure 入口網站 中使用這些查詢的詳細資訊，請參閱Log Analytics教學課程。 如需 REST API，請參閱 查詢。

HTTP 回應碼的餅圖

過去12小時內每個計量的響應碼明細。

AzureMetrics 
| where TimeGenerated > ago(12h)  
| where MetricName in ("Http2xx", "Http3xx", "Http4xx", "Http5xx") 
| summarize sum(Total) by MetricName  
| render piechart

回應時間折線圖

平均回應時間的時間序列（超過 5 分鐘間隔）。

AzureMetrics 
| extend timeBin = bin(TimeGenerated, 5m) 
| summarize ResponseTime = sumif(Average, MetricName=="AverageResponseTime") by timeBin, bin(TimeGenerated, 1h) 
| sort by TimeGenerated desc 
| render timechart

[傳統]在 AzureMetrics 中尋找

[傳統]在 AzureMetrics 中尋找以搜尋 AzureMetrics 數據表中的特定值。/nNote 指出此查詢需要更新 <SeachValue> 參數以產生結果

// This query requires a parameter to run. Enter value in SearchValue to find in table.
let SearchValue =  "<SearchValue>";//Please update term you would like to find in the table.
AzureMetrics
| where * contains tostring(SearchValue)
| take 1000

最新計量

顯示每個報告計量的最新計量報告。

AzureMetrics 
| summarize arg_max(TimeGenerated, UnitName, Total, Count, Maximum, Minimum, Average) by MetricName

平均 CPU 使用量

依資源名稱在最後一小時內平均CPU使用量。

//consistently high averages could indicate a customer needs to move to a larger SKU
AzureMetrics
| where ResourceProvider == "MICROSOFT.SQL" // /DATABASES
| where TimeGenerated >= ago(60min)
| where MetricName in ('cpu_percent') 
| parse _ResourceId with * "/microsoft.sql/servers/" Resource  // subtract Resource name for _ResourceId
| summarize CPU_Maximum_last15mins = max(Maximum), CPU_Minimum_last15mins = min(Minimum), CPU_Average_last15mins = avg(Average) by Resource , MetricName

效能疑難排解

系統上可能會導致效能不佳的查詢或死結。

//potentially a query or deadlock on the system that could lead to poor performance
AzureMetrics
| where ResourceProvider == "MICROSOFT.SQL"
| where TimeGenerated >=ago(60min)
| where MetricName in ('deadlock')
| parse _ResourceId with * "/microsoft.sql/servers/" Resource // subtract Resource name for _ResourceId
| summarize Deadlock_max_60Mins = max(Maximum) by Resource, MetricName

載入資料

監視過去一小時內的數據載入。

AzureMetrics
| where ResourceProvider == "MICROSOFT.SQL"
| where TimeGenerated >= ago(60min)
| where MetricName in ('log_write_percent')
| parse _ResourceId with * "/microsoft.sql/servers/" Resource// subtract Resource name for _ResourceId
| summarize Log_Maximum_last60mins = max(Maximum), Log_Minimum_last60mins = min(Minimum), Log_Average_last60mins = avg(Average) by Resource, MetricName

P2S 連線計數

過去 30 天的使用中 P2S 連線計數。

AzureMetrics
