Nodejs Transaction Snapshots

[Hugo.Giordano]

Hi,

I am fairly new to AppDynamics and I am a bit puzzled by some behaviours with Nodejs Transaction Snapshots. Could anyone explain the following?

A HTTP request comes into a Nodejs application and it makes another HTTP request to an external service. All the calls are async and there is no specific correlation setup.

I am expecting one outbound request for each inbound request. However, I sometimes see many outbound request calls. 

Is this because AppD is just sampling the process, at the time of the snapshot, and showing all outbound calls occurring at that time? 

Many Thanks

H
