I would guess that there is a firewall between the Hyperic server and vROps that prevents Hyperic from sending the metrics to vROps.
I can see the Resource Objects in vRops just none of the collected data...its like I am missing some specific configuration that allows the data from Hyperic to populate into vRops.
The adapter is a two adapter:
1. vROps pulls the config and object information
2. Hyperic pushes the metrics
If you see #1 and not #2 then chances are that something is blocking access to your vROps server from Hyperic. It may be a firewall/network issue or the servlet that handles these requests is not working. Probably the firewall.
