memory and CPU not showing in Jupyter Lab 3.0

The bar does show on the top. I’m installing this with pip:

jupyterlab-topbar
jupyterlab-system-monitor

Running this in the docker file:

    jupyter labextension install jupyterlab-topbar-extension 
                             jupyterlab-system-monitor 
                             jupyterlab-topbar-text 
                             jupyterlab-theme-toggle

Launching it with this:

jupyter lab \
  --NotebookApp.ResourceUseDisplay.mem_limit=$(( 16 *1024*1024*1024 )) \
  --NotebookApp.ResourceUseDisplay.track_cpu_percent=True \
  --NotebookApp.ResourceUseDisplay.cpu_limit=$(( 16 )) \
  --NotebookApp.allow_origin='*' \
  --NotebookApp.base_url=/ \
  --NotebookApp.log_format='%(message)s' \
  --NotebookApp.log_level='INFO' \
  --NotebookApp.password='' \
  --NotebookApp.token='' \
  --ip=0.0.0.0 \
  --no-browser \
  "--notebook-dir=$HOME" \
  --port=8888

The toolbar shows with the “Hello” and theme switch but not the memory and CPU.

I also have the same problem. CPU not showing, only memory is showing.

@jtpio thanks. It now shows the memory - only the label and the memory consumed (without the total like in the readme) and without the spike chart. It’s not showing the CPU.

this is from the log:
