尝试以以下格式从Azure应用程序Insights中提取查询中特定时间范围的请求计数和响应时间

let startDatetime = todatetime("2023-03-15 14:00:00.0");
let endDatetime = todatetime("2023-03-15 15:45:00.0");
requests
| summarize RequestsCount=sum(itemCount), AverageDuration=avg(duration), percentiles(duration, 50, 95, 99) by operation_Name 
| order by RequestsCount desc // order from highest to lower (descending)
| where timestamp > startDatetime and timestamp < endDatetime

运行查询时出现以下错误
'where' operator: Failed to resolve column or scalar expression named 'timestamp'

在对结果进行分组之前，需要使用where语句，因为timestamp不是组的结果集中的列。
试试看

let startDatetime = todatetime("2023-03-15 14:00:00.0");
let endDatetime = todatetime("2023-03-15 15:45:00.0");
requests
| where timestamp > startDatetime and timestamp < endDatetime
| summarize RequestsCount=sum(itemCount), AverageDuration=avg(duration), percentiles(duration, 50, 95, 99) by operation_Name 
| order by RequestsCount desc // order from highest to lower (descending)
