Failed to show CPU usage in the pip installation

[euigfdbguiwerin93]

Hi! Thank you for this really useful plugin! I tried to follow the README and install the plugin via pip but failed to see the CPU usage even if I configured as guided.

However, then I followed the process of https://github.com/jtpio/jupyterlab-system-monitor#development and successfully make CPU usage chart shown. Also, I need to run development process under the home directory of this repo.

I wonder if the plugin is not well packaged or the artifacts are not well linked?

same problem here. latest ubuntu. latest python3 and jupyter lab. there was no jupyter notebook config file so i created it by jupyter notebook --generate-config and set it up as suggested here.

c.ResourceUseDisplay.mem_limit = 30000000000
c.ResourceUseDisplay.track_cpu_percent = True
c.ResourceUseDisplay.cpu_limit = 20

I now have memory usage figure but not the graph and no CPU usage.

I tried to use command line with the same effect

jupyter lab --NotebookApp.ResourceUseDisplay.mem_limit=$(( 30000000000 ))             
                  --NotebookApp.ResourceUseDisplay.track_cpu_percent=True
                  --NotebookApp.ResourceUseDisplay.cpu_limit=$(( 20 ))

Hey everyone,

I also have the same problem. I have JupyterLab3.6.1 installed in an conda environment and I installed this extnesion via pip install jupyterlab-system-monitor.

Were you only able to show the CPU usage via development installation? I was also not able to install it on JupyterLab3.6.2 via development installation due to an error:

Closing as jupyterlab-system-monitor has now been integrated in jupyter-resource-usage: https://github.com/jupyter-server/jupyter-resource-usage/issues/191

Feel free to open a new issue on the jupyter-resource-usage repo if needed: https://github.com/jupyter-server/jupyter-resource-usage

Thanks!
