Memory tab shown as 0 after installing system monitor extension

[felihong]

Hi there,

thanks for the lovely extensions. I installed the monitor extension as described in the doc:

jupyter labextension install jupyterlab-system-monitor
pip install nbresuse

However the memory tab surfaced remains 0:

Some environments:

• JupyterLab 1.2.5
• Notebook 6.0.3
• Python 3.7.6

Any ideas? Thanks.

@Felihong is this still happening after configuring nbresuse?

Hi @jtpio , thanks for your reply.

I edited the ~/.jupyter/jupyter_notebook_config.py by adding:

c.NotebookApp.ResourceUseDisplay.mem_limit = Size_of_GB *1024*1024*1024

but the memory remains as before. And this happens in my notebook container running a GKE pod. However in my personal Mac the temporal memory usage is well presented which makes me confused.

Was the file edited after the pod was started? Or is it mounted as a volume?

This would otherwise require a restart of the server.

[felihong]

Yes I modified the config file after the server was launched:

cat jupyter_notebook_config.py| grep "mem_limit"
c.NotebookApp.ResourceUseDisplay.mem_limit = '0.1*1024*1024*1024'

Is a restart still required in this case?

[jtpio]

Yes. The other way would be to specify the mem_limit on the spawner (assuming the GKE pod is started with ZTJH), and nbresuse would pick it up: https://github.com/yuvipanda/nbresuse#memory-limit

But even without setting the limit there should be some value:

Closing as this should be addressed in the jupyter-resource-usage repo, maybe as part of https://github.com/jupyter-server/jupyter-resource-usage/issues/191.
