Since the HA design holds a significant purpose in the vRealize automation distributed architecture, concluding that the failover test has been a success is an absolute step before endorsing it as a production-ready setup.
Testing the failover for every component is mandatory and the recipe for a successful failover is to follow the steps in a logical sequence for CAFÉ and Manager Service as described in this chapter. The failovers of other components are straightforward and does not require special instructions during and after the failover.
If you want to track the failure component, I would recommend the following approach:
Check in the load balancer pool setting if the required nodes are in the UP state
Corroborate whether the expected health monitor string is received by surfing the health monitor URL for every component behind the load balancer
Exercise the health monitor URL against the nodes directly bypassing the load balancer, especially for the component that has the active...
