response of api/metrics/v1 does not contain cpu metric

[Abdellah91]

Hello,
I installed plugin jupyter-resource-usage on a jupyterhub. the jupyterhub is deployed via helm chart on kubernetes cluster. When a request is sent to /api/metrics/v1 the response is {"rss": 112574464, "limits": {"memory": {"rss": 2147483648, "warn": false}}}. In the values.yml, of the jupyterhub helm chart config I have:
hub:
extraConfig:
firstConfig.py: |
c.ResourceUseDisplay.track_cpu_percent = True

Do you know why the cpu metric is not in the response of the api call?

[welcome]
