# ============================================================
# Script Name: Plex Transcoding & Docker Management Script
# Author: Admin9705 & Reddit
# Description:
# This script monitors Plex transcoding activity on a specified
# GPU device. If Plex is detected using the GPU, it resets a
# restart counter. If Plex does not use the GPU for a defined
# number of checks, it increments a counter. Once the counter
# reaches a threshold, the script restarts a specified Docker
# container. The script is designed to run indefinitely and
# includes logging for monitoring and troubleshooting.
# ============================================================
# NOTE: Requires Tautulli
