Application Insight Analytics Pivot

Question

有没有办法在Azure应用程序洞察分析查询中进行转换？ SQL有一个Pivot Keyword，可以在Application insight Analytics中实现类似吗？

当我运行以下查询时，我会获得例外和计数，但我希望看到一天中的趋势

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_ 

我正在寻找一天下面的东西。

Answer 1

实现类似于您需要的东西的最简单方法是使用：

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

这将在输出中为每天每行输入一行。不完全是你想要的，但是当在图表中渲染时它看起来会很好（会为每种类型提供一条线）。

要获得类似于您在示例中放置的表格会更困难，但此查询应该可以解决问题：

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
