建设部网站投诉核查企业名单比尤果网做的好的网站

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https://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

@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%.perfettoif exist trace_%timestamp%.perfetto (echo ✅ 文件已成功导出到当前目录：echo     trace_%timestamp%.perfettoecho.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 UIstart "" 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
