Question

如何透視App Insights分析查詢的結果？

例如，我想對每一個cloud_RoleInstace值列：

performanceCounters 
| where timestamp > todatetime("2017-07-24T13:44:00.251Z") 
    and timestamp < todatetime("2017-07-24T13:49:00.251Z") 
| where name in ("% Processor Time")//, "Request Execution Time") 
| sort by timestamp asc nulls last 
| project timestamp, value, cloud_RoleInstance 

Answer 1

是，只需添加

| evaluate pivot(cloud_RoleInstance) 

或者可能更復雜，但也許更正確的：

| summarize value=sum(value) by bin(timestamp, 1m), cloud_RoleInstance 
| evaluate pivot(cloud_RoleInstance, sum(value)) 

到您的查詢:)

也，可以簡化您的查詢的部分時間使用between操作

| where timestamp between(todatetime("2017-07-24T13:44:00.251Z")..todatetime"2017-07-24T13:49:00.251Z")
