Auto culling Jupyterhub notebooks

[manics]

Have a read through this, it explains some of the complexity behind culling servers/kernels:

Which is the correct way to cull idle kernels and notebook?

While the two aim in general to solve the same category of problem (wasted resources), they have different metrics available and different levels of action to take. The notebook-environment configuration should in general produce better, more fine-grained results because it can do things like cull unused kernels and be aware of things like idle/busy or connected status. This lets the notebook server make more intelligent choices like “shutdown a kernel if it’s been idle for 5 minutes BUT not if…

Please clarify
Also I assume after the culling, do we have to run the paragraph from the beginning again and we can not continue from where we left before culling?

I’m not sure what you mean by “paragraph”, do you mean a notebook cell? If so then you’ll have to run the notebook again from the beginning, since killing a kernel means all your internal state is lost.
