Opmanager v12 having issue with latest devices and WAN link monitor

Opmanager v12 having issue with latest devices and WAN link monitor

Hello Team,

1) We have added Cisco 4451X routers and 3850X switches but device homepage we are not getting            performance monitor dial like temperature and other. 
Do Opmanager support IOS XE devices ? Or all the MIB is included in opmanager v12. 

2) Second is backplane monitor is not working in all Cisco devices. 
3) WAN link monitor can not add Ethernet link.
4) While fetching wan link availability report it must show wan interface availability not parent device. As branches having two wan link will not show proper result due to one link will always up so we can not get report of availability of indivisual link.
