性能数据收集

[pqs-fly]

tidevice perf -o fps,mem,cpu -B com.example.demo ，这个命令现在还没有完成吗？

[codeskyblue]

0.4.5 试试

[jongyu]

刚试了一下,用命令行执行几秒钟就没了

fixed in 0.4.6

报错了

C:\Users\xxx>tidevice perf -B com.lyyd.demo

0.4.6

[codeskyblue]

0.4.8再试试

[lycfr]

@codeskyblue 执行一会发现报错，程序堵住了

我更新到最新0.4.8；手机用的是iPhone11 14.0.1系统；看着好像是解析fps的时候报错，然后就不行了。用的场景是：待机在一个相机app预览页界面

网上其他人提出的解决办法 https://www.cnblogs.com/vitas/p/9025857.html 用管理身份运行cmd，执行 netsh winsock reset 重启问题解决

先试试 @lycfr

[lycfr]

问题还是会出现的，没法弄。就解析fps的数据出不来。其他如果程序没堵住的话，还是会打印出来的。如果堵住就没法输出了。有单独指定采集性能数据的指令吗？比如，我想单独采集内存或者CPU，或者同时采集某几个性能数据

這個問題怎么解决

能不能监控到app级别的耗电情况？
