List available properties for console command displayall?

How do I know which properties are available for the console command "displayall "?
For example I want to know the transforms of the few static meshes i placed in the level.
I can get location and rotation by issuing commands “displayall StaticMeshActor location” and “displayall StaticMeshActor rotation” but i can’t get scale with “displayall StaticMeshActor scale”?
I also tried with a character blueprint but could get only location and rotation, not the scale.
