Hi All,

I have a scenario that is a chain of 2 sequential requests that I’m not sure how should I model.  
I’ve implemented the scenario using a group like below:

.group(“mygroupl”){  
exec( http(“req1”)  
.post(“[https://URL1](https://URL1)”)  
.body(StringBody("…"))  
.check(…).saveAs(“xxx”)))

.exec( http(“req2”)  
.post(“[https://URL1](https://URL1)”)  
.body(…)  
.check(status.is(200)))  
}

The user does not perceive that there are 2 requests involved and see it as a single action.  
I need to measure the response time of both requests and if req2 fails, the sample time of req1 should be computed as KO.  
Is there a way to report this aggregate time and status?  
I’m looking for the “Transaction Controller” semantics from jmeter.
