There are two options for bringing in HP server metrics and marrying them to vSphere resources.
1) HP OneView for VMware vCenter Operations Manager - My understanding is this requires OneView Enterprise, and it looks like it is not certified for vRealize Operations, but rather was built for vCenter Operations 5.8.x. This makes me question compatibility with vROps. More information can be found here: Cloud Management Marketplace | Solution Exchange
2) Blue Medora has a vRealize Operations Management Pack for HP Servers, which connects directly to the REST API on your HP ILOs. It can be found here: vROps Management Pack for HP Servers - Blue Medora
Yes, this is what i'm looking for. In fact I have HP Oneview Adapter installed but I dont have this view
These relationships have been available as long as I can remember with the HPE OneView Adapter, but I'm currently running vROps 7.5 and HPE OneView Adapter 2.3.021. Blue Medora is not necessary for the relationships. This should "just work" if you're running Synergy blades, the HPE customized ESXi image and name the server profile the same as your ESXi hostname. For rack mount, you have to install the VIBs.
Here are Blue Medora's pre-reqs for seeing the relationships, which I believe are the same for the OneView Adapter, but I'm not positive--haven't tested any rack mounts.
You can see relationships with several widgets. "Object Relationship (Advanced)" is pretty nice as you can set the depth of Parents and Children and explore. The non-Advanced version doesn't have that feature and only shows 1 Parent and 1 Child.
