Application Insight Analytics樞軸

Question

Azure應用程序洞察分析查詢中是否有方法可以實現樞軸轉向？ SQL有一個Pivot Keyword，可以類似的在Application insight Analytics中實現嗎？

當我運行下面的查詢，我得到的例外和計數，但我希望看到在一天一天走向

exceptions 
| where timestamp >= ago(24h) 
| extend Api = replace(@"/(\d+)",@"/xxxx", operation_Name) 
| summarize count() by type 
| sort by count_ desc 
| limit 10 
| project Exception = type, Count = count_ 

我找下面的一天明智的事情。

Answer 1

來實現類似的東西，你需要什麼，最簡單的方法是使用：

exceptions 
| where timestamp >= ago(7d) 
| summarize count() by type, bin(timestamp, 1d) 

這將在每個類型的輸出一行裏，每一天。不完全是你想要的，但它在圖形中呈現時會看起來不錯（每個類型都會給你一行）。

要獲得類似於你把你的例子是比較困難的表，但此查詢應該做的伎倆：

exceptions 
| where timestamp >= startofday(ago(3d)) 
| extend Api = replace(@"/(\d+)",@"/xxxx", operation_Name) 
| summarize count() by type, bin(timestamp, 1d) 
| summarize 
    Today = sumif(count_, timestamp == startofday(now())), 
    Today_1 = sumif(count_, timestamp == startofday(ago(1d))), 
    Today_2 = sumif(count_, timestamp == startofday(ago(2d))), 
    Today_3 = sumif(count_, timestamp == startofday(ago(3d))) 
    by type
