top/bottom bar cpu usage shows 0%

[stanfish06]

Hi! My CPU usage always shows 0%, which is different from the value shown in the kernel usage panel.
This is my topbar-item.jupyterlab-settings.json
{ "enable": true, "refreshRate": 1000, "memory": { "label": "| Mem: " }, "cpu": { "cpu": "CPU: " }, "disk": { "label": "| Disk: " } }
I have this line added in my jupyter_lab_config.py
c.ResourceUseDisplay.track_cpu_percent = True
I installed jupyterlab 4.4.9 and jupyter-resource-usage 1.2.0.

Thank you!

Here are some additional information. I added print statements to the api.py:

if config.track_cpu_percent:
   cpu_count = psutil.cpu_count()
   cpu_percent = await self._get_cpu_percent(all_processes)
   print(all_processes)
   print(cpu_percent)

When I ran a single cell I got

[psutil.Process(pid=11577, name='jupyter-lab', status='running'),
 psutil.Process(pid=11779, name='python3', status='sleeping', started='14:43:43'),
 psutil.Process(pid=11807, name='python3', status='sleeping', started='14:43:44'),
 psutil.Process(pid=11840, name='python3', status='sleeping', started='14:43:46')]
0.0

So I thought it might miss some kernel process, and I added

cur_process = psutil.Process()
all_processes = [cur_process] + cur_process.children(recursive=True)
additional_processes = []
for p in psutil.process_iter(["pid", "name", "cmdline"]):
    try:
        cmd = " ".join(p.info["cmdline"])
        if any(k in cmd for k in ["jupyter-lab", "ipykernel", "jupyter-kernel"]):
            additional_processes.append(p)
    except psutil.NoSuchProcess:
        continue
all_processes = all_processes + additional_processes

Then it greps jupyter-lab processes twice:

[psutil.Process(pid=16730, name='jupyter-lab', status='running'),
 psutil.Process(pid=16896, name='python3', status='sleeping', started='15:00:24'),
 psutil.Process(pid=16949, name='python3', status='sleeping', started='15:00:26'),
 psutil.Process(pid=16984, name='python3', status='sleeping', started='15:00:27'),
 psutil.Process(pid=16730, name='jupyter-lab', status='running'),
 psutil.Process(pid=16896, name='python3', status='sleeping')]
112.4

Also the ui starts to show some cpu usages, though I'm not sure if that is accurate or not:

Could you help me look into this issue? Thanks!

I do have this problem aswell, disabling it until i have further updates
