Performance testing help needed
System A will post request via a service to system B (system under test), system B will just acknowlegde that request is received.
System B then creates an object which posts multiple request to systems C,D,E etc., automatically (there is no manual intervention).
After all of this is done, System B calls a new service and posts the updates to system A.
The goal is to determine the time taken by system B to post updates to system A after receiving the request from system A.
Please provide your help on how this can be done.
You have to store the first timestamp when. System A received acknowledge into some lightweight database or file. Then store the new timestamp after update was received. Then substract first from the second
Logs at each tier. Match up correlating identifiers for requests and timestamps
