By default, Blender only tells you current active object statistics. But as soon as you're doing realtime 3D, it's interesting to see whole scene polycount and be able to sort your meshes regarding heaviness.

Addon is only compatible starting to Blender 2.8 series.

You can download it from Github repository, as well as read its documentation.
