[Observium] Question BGP peers in VRF

Hi I am evaluating Observium for reading the number of received bgp routes on ASR9000 routers. I have successfully discovered one of our testrouters and I can see the bgp peers in the liste. However it only detects the vpnv4/vpnv6 bgp peers. It does not detect the bgp peers inside vrfs. Is there any possibility to do so? Apparently they should be read in CISCO-BGP4-MIB Regards Mihai
