Issue #, if available:
Description of changes:
Problem: The
sagemaker-idle-extensionchecks if there is an active terminal session by checking for the existence of/dev/ptsentries in the file system. However, when the user closes the Code Editor browser tab, thesagemaker-idle-extensionis deactivated, so even if an active terminal process is still running, the idle shutdown countdown starts.Solution: We move the
checkTerminalActivityfunction to the/api/idlehandler on the code server side, so that it runs even when the browser tab is closed. The/api/idleendpoint is called by the SageMaker Studio service on a 1-minute interval to determine whether the Code Editor instance is idle or not.By submitting this pull request, I confirm that you can use, modify, copy, and redistribute this contribution, under the terms of your choice.
