序言
最近在研究性能问题需要抓取trace文件。于是写了个脚本
使用
双击运行批处理文件,可以开始记录trace。而且以当前文件夹下面的。config.pbtx 作为配置文件。 (pbtx就是一个json文件。配置了需要抓取那些参数,可以通过ui.perfetto.dev/中的Record new trace (左侧)的菜单,在右侧设置最近要记录什么内容。来生成配置文件。可以参考Android Perfetto 系列 2:Perfetto Trace 抓取
最后的文件在Cmdline instructions菜单中显示。
右边下方的内容拷贝到。当前目录,并命名为config.pbtx 记得把配置中的时间去除,这样可以一直记录。
在当前文件夹下新建批处理
bat
@echo off
chcp 65001 >nul
@echo off
setlocal enabledelayedexpansion
:: 获取当前目录
echo 当前目录: %cd%
:: 使用 PowerShell 获取时间戳
for /f "delims=" %%a in ('powershell.exe -Command "Get-Date -Format yyyyMMdd_HHmmss"') do set timestamp=%%a
echo 时间戳: %timestamp%
:: 删除旧 trace 文件
adb shell rm -rf /data/misc/perfetto-traces/trace.perfetto
timeout /t 1 >nul
:: 推送配置文件
adb push config.pbtx /data/misc/perfetto-configs/config.pbtx
timeout /t 1 >nul
:: 开始录制
echo 开始记录 trace,请按 Ctrl+C 结束录制...
adb shell -tt perfetto --txt -c /data/misc/perfetto-configs/config.pbtx -o /data/misc/perfetto-traces/trace.perfetto
:: 导出 trace 到当前目录
adb pull /data/misc/perfetto-traces/trace.perfetto .\trace_%timestamp%.perfetto
if exist trace_%timestamp%.perfetto (
echo ✅ 文件已成功导出到当前目录:
echo trace_%timestamp%.perfetto
echo.
echo 🔗 正在打开 Perfetto 官方网站,请稍后手动上传 trace 文件。
echo 1. 浏览器将自动打开 Perfetto UI。
echo 2. 点击左上角 ^> Open trace file^> 按钮。
echo 3. 选择刚刚保存的 trace_%timestamp%.perfetto 文件。
echo.
:: 打开默认浏览器访问 Perfetto UI
start "" https://ui.perfetto.dev/
) else (
echo ❌ 文件未找到,请检查设备路径或配置。
)
pause
双击bat运行,要结束录制的话,只需要按下 Ctrl+C 就可以了。 最后文件会自动保存到当前文件夹下,以时间命名。
最后还会自动打开分析网站。只需要把日志文件拖入浏览器就可以打开。
附带配置
这是我的配置文件,可以记录logcat
