NB Resource (nbresource) is a small extension for Jupyter Notebooks that displays an indication of how much resources your jupyter server and its children (kernels, terminals, etc) are using.
You can currently install this package from PyPI.
pip install git+https://github.com/wixb50/nbresource.git
If your notebook version is < 5.3, you need to enable the extension manually.
jupyter serverextension enable --py nbresource --sys-prefix
jupyter nbextension install --py nbresource --sys-prefix
jupyter nbextension enable --py nbresource --sys-prefix
