trace配置及命令文件

大家好，欢迎来到IT知识分享网。

1. 配置文件：config.txt

buffers: { size_kb:  fill_policy: RING_BUFFER } buffers: { size_kb: 2048 fill_policy: RING_BUFFER } data_sources: { config { name: "linux.process_stats" target_buffer: 1 process_stats_config { scan_all_processes_on_start: true proc_stats_poll_ms: 1000 } } } data_sources: { config { name: "linux.sys_stats" sys_stats_config { stat_period_ms: 1000 stat_counters: STAT_CPU_TIMES stat_counters: STAT_FORK_COUNT } } } data_sources: { config { name: "linux.ftrace" ftrace_config { ftrace_events: "block/*" ftrace_events: "sched/sched_switch" ftrace_events: "power/suspend_resume" ftrace_events: "sched/sched_wakeup" ftrace_events: "sched/sched_wakeup_new" ftrace_events: "sched/sched_waking" ftrace_events: "power/cpu_frequency" ftrace_events: "power/cpu_idle" ftrace_events: "power/gpu_frequency" ftrace_events: "sched/sched_process_exit" ftrace_events: "sched/sched_process_free" ftrace_events: "task/task_newtask" ftrace_events: "task/task_rename" ftrace_events: "ftrace/print" atrace_categories: "am" atrace_categories: "adb" atrace_categories: "aidl" atrace_categories: "dalvik" atrace_categories: "audio" atrace_categories: "binder_lock" atrace_categories: "binder_driver" atrace_categories: "bionic" atrace_categories: "camera" atrace_categories: "database" atrace_categories: "gfx" atrace_categories: "hal" atrace_categories: "input" atrace_categories: "network" atrace_categories: "nnapi" atrace_categories: "pm" atrace_categories: "power" atrace_categories: "res" atrace_categories: "rro" atrace_categories: "sm" atrace_categories: "vibrator" atrace_categories: "video" atrace_categories: "view" atrace_categories: "webview" atrace_categories: "wm" atrace_apps: "*" } } } duration_ms: 15000 

2. 抓trace的命令文件： perfetto.sh

备注说明：生成一个.html结尾的，保存在“/home/xadz1307/trace/”的文件。

#!/bin/bash
date_time=$(date +"%Y_%m%d_%H%M")
echo $date_time
product_name=`adb shell getprop ro.product.name`
FILE_NAME=$product_name"_"$date_time
echo $FILE_NAME
CURRENT_PATH=$(cd $(dirname $0); pwd)
echo $CURRENT_PATH
TRACE_PATH=/home/xadz1307/trace/

adb push config.txt /data/misc/perfetto-traces/config.txt

adb shell "perfetto -c /data/misc/perfetto-traces/config.txt --txt -o /data/misc/perfetto-traces/$FILE_NAME.html"

adb pull /data/misc/perfetto-traces/$FILE_NAME.html $TRACE_PATH

3. 打开trace文件：

google浏览器-打开网站Perfetto UI–  –> 选项：open trace file
