LightLLM Profiler 使用说明

使用场景

当用户需要使用 LightLLM profiler 功能时使用本 skill，包括：

  • 启动服务时打开 profiler 能力。
  • 通过 HTTP 接口控制 profiler start / stop。

启动方式

服务启动时增加 --enable_profiling：

python -m lightllm.server.api_server \
  --model_dir /path/to/model \
  --enable_profiling torch_profiler

支持值：

  • torch_profiler：启用 PyTorch profiler，trace 默认写入 ./trace，也可通过 LIGHTLLM_TRACE_DIR 指定目录。
  • nvtx：启用 NVTX range，配合 NVIDIA Nsight Systems 等外部工具采集。

未设置 --enable_profiling 时，/profiler_start 和 /profiler_stop 会返回未启用提示。

HTTP 控制接口

启动 profiler：

curl http://127.0.0.1:8000/profiler_start

停止 profiler：

curl http://127.0.0.1:8000/profiler_stop

端口 8000 替换为服务启动时的 --port。
