Is there a way we can detect idle sessions. For example a user requests an interactive Jupyter-notebook uses it for few minutes closes the browser and then leaves the job running until its expiration time. I understand this is more of an education thing to the users, but a bit unhappy about how users request an interactive session for N > 12 hours of the job and leave it unused after 5 minutes. We could make interactive sessions short but that might not work some good users. Any thoughts on how others are dealing with this? Not sure if I want to police and ping every user on this, but would like to be alerted on such sessions if possible and as a first step identify how much of an issue this is.
