从抓Perfetto log 到log的解析，Perfetto 与systrace log有很大的不同。Perfetto把很多系统级的log如单个进程的memory/GPU ion/adj/native/java memory debug/proc/stat /logcat/CPU freq/CPU 调度/CPU C stat/power 电压/电池的使用/syscall 等merge 在一起，一并在UI 上显示出来，可以观察到引起系统性能的各个因数。不夸张的说，如果能看懂Perfetto 在抓log界面里面设置每一项是什么意思，能抓到哪些log，那么你对性能的调试可以算已经入门，否则，需要进一步学习。
从Perfetto UI 抓取 Perfetto log

也可以在手机上手动执行抓perfetto log
