[Observium] Observium graphs not populated on Cisco

*Hello there,*

*We have just added a new 1002-X ASR with the following software.*

*Cisco IOS Software [Amsterdam], ASR1000 Software (X86_64_LINUX_IOSD-UNIVERSALK9-M), Version 17.3.3*

*The device is polled just fine, all Interfaces, included subifs indexed correctly and everything seems ok.* *But observium shows data on only on physical interfaces, but not to Subinterfaces.* *To be more specific, it graphs only physical interfaces, but not routed VLAN interfaces.*

*Have you ever seen anything like this?*
