The test is divided up into 3 tests across 3 VMs:
- Stability-Test-VM1 LCM Group (Restart VM)
- Stability-Test-VM2 LCM Group (Stop VM & Start VM)
- Stability-Test-VM3 LCM Group (Rebuild VM)
The test itself can be set to loop indefinitely or a set number of loops. The LCM action request is submitted from the Test Client server to DMaaP where APPC picks up the request. APPC will send back an ACCEPT or REJECT for the request in a synchronous fashion. However, the response for the completed action (SUCCESS or FAILURE) is returned in an asynchronous fashion. The JMeter test is developed in such a way that it polls (Does a GET) DMaaP checking for the presence of the response based on the request_id. If the response is not receive ed within a set time the Async Listener will timeout.
