+llama-watch brings live monitoring of your llama-swap LLM server to your Stream Deck. Watch in-flight request counts per model with a real-time activity spark, switch to Usage stats to see request totals, processed and generated tokens, and the generation-speed P95 — per model or across all models. GPU Graph keys render live line charts of GPU utilization, VRAM, temperature, power draw, and fan speed — for one GPU, all GPUs, or a custom combination.
+
+Features
+- In-Flight Monitor: live per-model request count with a 60-second activity spark; Usage stats display (requests, processed/generated tokens, generation-speed P95) per model or all models.
+- GPU Graph: live charts for utilization, VRAM, temperature, power draw, and fan speed — single GPU, all GPUs, or a custom combination.
+- Per-key configuration: base URL and optional API key; every key is independent.
+
+Requirements
+- A running llama-swap instance (open source) and its base URL — default http://localhost:9292.
+- Optional API key for protected instances.
+- macOS 13 or later; Stream Deck 7.1 or later.
+
+Privacy: the plugin reads data only from your configured llama-swap server and sends nothing elsewhere. No analytics, no telemetry.
