RAM or CPU show nothing

Hello,

I’ve been trying this extensions but it seems nothing happened. I use Kubernetes for deployment. Here my versions:

jupyter-client         5.3.4              
jupyter-console        6.1.0              
jupyter-core           4.6.3              
jupyter-rsession-proxy 1.1                
jupyter-server-proxy   1.3.2              
jupyterhub             1.0.0              
jupyterlab             1.2.13             
jupyterlab-server      1.1.1              
nbresuse               0.3.4              
notebook               6.0.2              
prometheus-client      0.7.1              
psutil                 5.7.0

Some of error logs shown:

[E 2020-04-30 06:15:22.373 SingleUserLabApp ioloop:763] Exception in callback functools.partial(<bound method IOLoop._discard_future_result of <tornado.platform.asyncio.AsyncIOMainLoop object at 0x7f896ed2f668>>, <Future finished exception=AttributeError("can't set attribute",)>)

        metrics.max_memory = self.config.mem_limit
    AttributeError: can't set attribute

Here the configurations that i use to spawn the notebook:

c.KubeSpawner.args = ['--disable-user-config', '--no-browser', '--allow-root',
    '--config=/etc/jupyter/jupyter_notebook_config.py',
    '--ResourceUseDisplay.track_cpu_percent=True']

Appreciate for helping. Thank you.

Hi @jtpio

You are right, after upgrading Jupyterlab with version 2.1.1 and use nbresuse==0.3.3 now RAM and CPU usage are shown.

Thanks

[sundh4]

So, this mean the extensions only work for Jupyterlab version 2.x.x right?

Yes, version 0.5.0 and above only support JupyterLab 2.0.

The CPU indicator was added after the update to 2.0 and will not be backported to 1.x. Most of the extensions in the list above should now be compatible with the latest JupyterLab. Is it possible to upgrade to JupyterLab 2.x on your setup?

Thanks @jtpio

I see, will try upgrade my setup with version 2.xx. I will update the result here.
