Hi ,
You can't really see the BGP neigbhors status from the dashboard. You can check the Event Logs "BGP session established" , " BGP session no longer established" , "BGP sent notification".
You can also check the routing table to see if you have learned some eBGP routes.
Taking a packet capture to see the BGP keepalives can also be a way to confirm the status.
iBGP is between the spoke and the HUB and eBGP is between the HUB and probably your DC
