请求遥测采样期间context遥测是否已“分组”？

例如，下面的数据包含一个样本数为10（"count": 10）的请求，这意味着它用于表示其他9个“类似”请求; 90％的遥测实际上已被丢弃。

当请求的上下文数据完全相同时，Application Insights是否仅将数据一起采样？例如，我是否可以假设其他9个请求也来自41.191.204.0并且自定义字段company的值为22f0141f-b3dc-53e1-86b8-dd0727c14497？

Application Insights不会根据上下文对遥测事件进行分组，但会根据操作ID进行分组。这在SDK采样和服务器端采样之间同步，以确保您能够在相关的页面查看和请求之间导航。

因此，如果您想确保某些事件在采样中组合在一起，请将其OperationId设置为相同。

希望这有帮助，
