Leao,
Did this ever get answered/resolved?
Diego's response is the likely correct answer.
First the device hosting the target tests must be discovered in the Data Aggregator. Once that is done, tie the various Response Path Metric Families to the discovered device via a Collection using Monitoring Profiles.
Once that is done, do any of the expected Response Path tests get discovered and created as Component Elements in the DA to start polling them for data collection?
Thanks,
Mike
