Currently we are using pcp for collecting the ros metrics, the same metrics can be collected now via pcp zeroconf and we need to verify there is consistency even after we are collecting the metrics via PCP zeroconf.
Steps to verify:

1. Create a VM
2. Configure it to use pcp zeroconf
3. Validate that it's able to collect all the required metrics

Note: our current test performs validation based on metrics, and state of VM is decided based on those metrics. 

If there is consistency is value collections then we don't have any issues from the service point of view.
