memory and CPU not showing in Jupyter Lab 3.0

[yosit]

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.

Thanks @yosit for reporting.

Have you tried installing the extension with pip?

pip install jupyterlab-system-monitor

Instead of jupyter labextension install.

[ladychili]

Same here. I installed jupyterlab-system-monitor with pip.
The top bar not showing metrics, and the terminal keeps returning those error

[yosit]

@jtpio from the instructions I understood I need to do both pip install and jupyter labextension install

I see similar logs like @ladychili

[iicky]

I'm also getting the same logs. I have only run pip install jupyterlab-system-monitor to install. Here's the versions I am currently running:

# pip freeze | grep jupyterlab
jupyterlab==3.0.9
jupyterlab-pygments==0.1.2
jupyterlab-server==2.3.0
jupyterlab-system-monitor==0.8.0
jupyterlab-topbar==0.6.1

Any idea where the endpoint /api/metrics/ went?

[jtpio]

from the instructions I understood I need to do both pip install and jupyter labextension install

@yosit with JupyterLab 3.0 the single pip install should be enough,

Any idea where the endpoint /api/metrics/ went?

This endpoint is exposed by jupyter-resource-usage: https://github.com/jupyter-server/jupyter-resource-usage, which should now be part of the dependencies:

jupyterlab-system-monitor/setup.py

Line 71 in a05a27d

"jupyter-resource-usage~=0.5"

[yosit]

@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:

Edit: Never mind. Leaving for posterity. It's because I'm running in k8s.

I'm having this same issue. It looks like the metrics api is only returning memory. Any idea why that would be happening?

{"rss": 275681280, "limits": {"memory": {"rss": 0}}}

[shoegazerstella]

I am having the same issue on jupyterlab 3.0.

jupyterlab @ file:///home/conda/feedstock_root/build_artifacts/jupyterlab_1616195786210/work
jupyterlab-drawio==0.8.0
jupyterlab-git==0.30.1
jupyterlab-nvdashboard==0.6.0
jupyterlab-pygments @ file:///home/conda/feedstock_root/build_artifacts/jupyterlab_pygments_1601375948261/work
jupyterlab-server @ file:///home/conda/feedstock_root/build_artifacts/jupyterlab_server_1617134349851/work
jupyterlab-system-monitor==0.8.0
jupyterlab-topbar==0.6.1
jupyterlab-widgets @ file:///home/conda/feedstock_root/build_artifacts/jupyterlab_widgets_1609173350931/work

Here's what it shows on the top bar:

[jtpio]

Linking to jupyter-server/jupyter-resource-usage#91 and jupyter-server/jupyter-resource-usage#86 which sound similar.

[paravatha]

@jabbera @jtpio I am using k8s and seeing the issue w.r.t CPU not showing. Memory stats works fine

[tlvu]

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

[scottwsides]

I've got the same error. The mem use number shows... but no bars. I'm running jupyterlab=3.3.0 and pip installing jupyterlab-system-monitor. Any progress?

[EnyMan]

I had to set the limits for the bars to show.
https://github.com/jtpio/jupyterlab-system-monitor#graphic-display

[scottwsides]

I set the limits in the startup for jupyterlab... but still no luck. Mem usage shows but no bars

[jtpio]

Closing as jupyterlab-system-monitor has now been integrated in jupyter-resource-usage: jupyter-server/jupyter-resource-usage#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!
