I'm working on a three tier QOS policy for use on an MPLS network. We are not running MPLS, the provider is. We are peering via BGP as 22 locations. The circuit speeds vary by site. My routers are ISR4351 in the offices and ASR1001-X in the two data centers.
Look at this configuration and see if I'm on the right track. I'm using LiveAction to monitor QOS. I'm seeing drops on an interface because of shaping. I have the shaping rate set to 100Mbps on a 100Mbps circuit so can't see why I would see class drops.

Hi Patrick,
Are the drops still appearing after making this change ?

I did see flowdrops. I bumped the queue size to 256 but I still see drops.
