在自定义 属性 上查询 AppInsights

Query AppInsights on a Custom Property

我记录了以下内容。有没有办法在 prop_CorrelationId in where 子句中查询 AppInsights?我尝试了以下方法,但都没有 return 信息。注意第一个违背“请求”,第二个违背“痕迹”:

let numberOfDaysAgo = ago(6d);
requests
| where timestamp > numberOfDaysAgo and customDimensions.prop_CorrelationId == "568abba7-6601-4159-a3b1-ef27b2437473"

let numberOfDaysAgo = ago(6d);
traces
| where timestamp > numberOfDaysAgo and customDimensions.prop_CorrelationId == "568abba7-6601-4159-a3b1-ef27b2437473"

显然,您在 prop_CorrelationId.

中错误地使用了 _ 而不是 __(它是双 _

所以请在查询中使用 prop__CorrelationId 而不是 prop_CorrelationId

例如:

let numberOfDaysAgo = ago(6d);
requests
| where timestamp > numberOfDaysAgo and customDimensions.prop__CorrelationId == "568abba7-6601-4159-a3b1-ef27b2437473"
