我正在编写关于过滤条件的 KQL,我想加入两个事件数据。我的 KQL 是这样的:
let table1=source
|where LogName == "FraudServiceRequest"
| project d_name=LogName,PreciseTimeStamp,ConnectionID,End=substring(TimeStamp,13,20);
let table2=source
| where LogName == "ProxyReceivedRequest"
| project ConnectionID,Start=substring(TimeStamp,13,20);
table1
| join (table2)
on $left.ConnectionID == $right.ConnectionID
|project ConnectionID,m_Ans=(toreal(End)-toreal(Start))/1000.0
但没有人记录回应。你能帮帮我吗,非常感谢。
