I am using jupyterhub/k8s-hub:2.0.0 container image which contains jupyterhub 3.0.0. I have cull service enabled but I cannot find the log files on what cull is doing. I scanned the Dockerfile of k8s-hub but cannot find anything there. If I understand this correctly, then idle-culler is using tornado to write logs but cannot find anywhere that tornado is configured to output the logs to some specific file on the container.
Assuming you’re using the default configuration the idle-culler is run as a managed JupyterHub service, so the logs will including in the hub logs. These should be visible using [
kubectl logs ...]
