cannlog: CANN simulation log parser and web viewer

Project description

cannlog

用于浏览和解析 cannsim 仿真日志的本地 Web 可视化工具。后端给定日志目录启动,前端在浏览器中动态查看日志、访存数据和指令关联关系。

安装

从 PyPI 安装:

pip install cannlog

从源码安装:

pip install .

开发模式安装:

pip install -e .

安装后主命令是 cannlog

cannlog /path/to/log_dir --host localhost --port 18000

也保留了兼容别名:cann-log-parsercann-log-viewer

也可以继续使用模块入口:

python -m cannlog.server /path/to/log_dir --host localhost --port 18000
python -m app.server /path/to/log_dir --host localhost --port 18000

打开:http://localhost:18000

默认 host 是 localhost,默认端口是 18000。如果不传 --port18000 被占用,会自动尝试后续端口;如果显式传了 --port,端口被占用时会直接提示并退出。

远程机器上运行时:

  • 如果使用 VS Code Remote,可以在 Ports/端口 面板中转发服务提示的端口,然后点浏览器图标打开。
  • 如果没有 VS Code 端口转发功能,在本地终端建立 SSH 隧道:
ssh -N -L 18000:127.0.0.1:18000 <user>@<ip>

然后在本地浏览器打开:http://localhost:18000。如果服务自动切换到了其它端口,把命令里的 18000 换成实际提示的端口。

已支持的日志类型

  • 指令日志:*.instr_log.dump*.instr_popped_log.dump
  • 访存日志:*.rd_log.dump*.wr_log.dump
  • PV 访存日志:*rvec_pv.dump,按指令 ID 合并 Rd/Wr 数据块并支持解码
  • CCU/队列事件:*.ccu_log.dump*issque.dump*.OOO.dump
  • PMU/summary:*.perf_pmu.log*.perf_pmu_per_vf.log*summary_log

功能

  • 给定日志目录启动本地 Web 服务
  • 前端动态加载文件树和事件页,大日志分页读取
  • 访存日志按指令 ID 合并展示;PV 日志中同一指令下相同读写和寄存器会合并,不同读写或寄存器会分块展示
  • 支持 hex32uint8/int8uint16/int16/float16/bfloat16uint32/int32/float32uint64/int64/float64 解码
  • instructionId 跨文件查询关联访存事件,并可跳转定位到具体事件
  • 支持分类、Core、Unit、文件名过滤
  • 支持多日志页签、右键菜单、新窗口打开、重载日志
  • 日志文件树和详情面板支持收起/展开

使用示例

cannlog /mnt/workspace/log/cann-sim/log_ca --host 0.0.0.0 --port 18000

打开:http://localhost:18000

API

  • GET /api/overview
  • GET /api/files
  • GET /api/file?path=...&page=1&pageSize=50
  • GET /api/stats?path=...
  • GET /api/instruction-memory?instructionId=4309

打包发布到 PyPI

安装构建和上传工具:

python -m pip install build twine

构建源码包和 wheel:

python -m build

检查包元数据:

python -m twine check dist/*

上传到 TestPyPI:

python -m twine upload --repository testpypi dist/*

上传到正式 PyPI:

python -m twine upload dist/*

发布前建议:

  • 确认 pyproject.toml 中的 name = "cannlog" 没有被 PyPI 占用
  • 为每次发布递增 version
  • 许可证已在 LICENSEpyproject.toml 中声明为 MIT

实现说明

  • 后端仅使用 Python 标准库,无运行时依赖
  • 前端为原生 HTML/CSS/JS,无需构建
  • 静态资源已作为 package data 打进 wheel,pip 安装后可直接运行
