I am not sure what you mean, but why would you export them and import them into vRealize Operations?
You can use the vRealize Operations Manager Tenant App for vCloud Director to get visibility into your vCloud Director environment.
To identify if a VM is a vApp template you may need The vRealize Operations Management Pack for vCloud Director. However, It is possible to identify if it is a VM template.
