Jupyterlab running on docker is very active

Hi,

I am running jupyter docker stack: Datascience container solely, only via jupyter server for my personal usage. Dozzle shows high activity, continous get from api as below in the screenshot.

Is it normal? Why jupyterlab is consuming resources when not active?

Thanks in advance, Oz.

It’s the built-in healthcheck:

github.com

jupyter/docker-stacks/blob/abea5caf78da2dbe1af0ded0b1e184191016ba57/images/base-notebook/Dockerfile#L68-L72


      
          # HEALTHCHECK documentation: https://docs.docker.com/engine/reference/builder/#healthcheck
          # This healtcheck works well for `lab`, `notebook`, `nbclassic`, `server`, and `retro` jupyter commands
          # https://github.com/jupyter/docker-stacks/issues/915#issuecomment-1068528799
          HEALTHCHECK --interval=3s --timeout=1s --start-period=3s --retries=3 \
              CMD /etc/jupyter/docker_healthcheck.py || exit 1

Thank you. Any chance to increase beat time?

I think you’ll need to derive your own image (FROM quay.io/jupyter/datascience-notebook:<TAG>), and set your own HEALTHCHECK command, or HEALTHCHECK NONE to disable it:
