What is gpu-sentinel-feishu?

GPU Sentinel Feishu is a small Linux background service that watches NVIDIA GPU servers remotely and sends you a notification in Feishu, a team messaging app, whenever the workload on those GPUs changes. Instead of flooding you with constant status updates, it only alerts you when something actually happens: a new process starts using a GPU, an existing process finishes, or the very first snapshot of activity is recorded. It connects to your GPU server over SSH, so it does not need to be installed on the GPU machine itself, it sits on any Linux computer that can reach that server. It uses the standard nvidia-smi tool on the remote machine to collect information about GPU utilization, memory usage, temperature, power draw, and which processes are running. All of that history is stored in a local SQLite database, a single file with no separate database server required. The notifications it sends are formatted as Feishu interactive cards, which can include collapsible sections showing the full command each GPU process is running, plus system stats like CPU load and uptime. You set up a Feishu group bot, give its webhook URL to the installer, and the service takes care of the rest. Installation runs through a shell script that asks for your SSH connection details, the webhook URL, and a few preferences, then registers a user-level systemd timer, a Linux scheduler, so the check runs automatically without requiring administrator access.
