一、Hidumper简介
HiDumper是OpenHarmony中为开发、测试人员，IDE工具提供统一的系统信息获取工具，帮助使用者分析，定位问题。
二、Hidumper设计原理和架构图

三、Hidumper使用方法
# hidumper -h
usage:
  -h                         |help text for the tool
  -t [timeout]             |timeout period in seconds (0 for no timeout)
  -lc                      |a list of system information clusters
  -ls                      |a list of system abilities
  -c                         |all system information clusters
  -c [base system]          |system information clusters labeled "base" and "system"
  -s                         |all system abilities
  -s [SA0 SA1]             |system abilities labeled "SA0" and "SA1"
  -s [SA] -a ['-h']          |system ability labeled "SA" with arguments "-h" specified
  -e                         |faultlogs of crash history
  --net                      |dump network information
  --storage                |dump storage information
  -p                         |processes information, include list and infromation of processes and threads
  -p [pid]                   |dump threads under pid, includes smap, block channel, execute time, mountinfo
  --cpuusage [pid]          |dump cpu usage by processes and category; if PID is specified, dump category usage of specified pid
  --cpufreq                |dump real CPU frequency of each core
  --mem [pid]                |dump memory usage of total; dump memory usage of specified pid if pid was specified
  --zip                      |compress output to /data/dumper
例如使用hidumper命令就可以将导出系统信息直接打印在终端，执行如下命令：
# hidumper --zip
100%,[-],The result is:/data/dumper/20091020-063620-502.zip
将导出的所有信息数据压缩成zip包
四、hidumper使用示例
1.下载压缩包数据
hdc file recv /data/dumper/20091020-063620-502.zip %cd%

使用解压工具提取使用功能3.数据类型需要核对

3.数据类型如下
每个核的cpu的频率
-------------------------------[cpufreq]-------------------------------
cmd is: cat /sys/devices/system/cpu/cpu5/cpufreq/cpuinfo_cur_freq
cpuusage：
-------------------------------[cpuusage]-------------------------------
Load average: 0.21 / 0.13 / 0.10; the cpu load average in 1 min, 5 min and 15 min
CPU usage from 2009-10-20 06:36:20 to 2009-10-20 06:36:21
Total: 11%; User Space: 0%; Kernel Space: 11%; iowait: 0%; irq: 0%; idle: 87%
Details of Processes:
PID Total Usage    User Space Kernel Space Page Fault Minor Page Fault Major Name
181    13%             0%          13%                0                0       sugov:2
具体涉及到cpufreq、cpuusage、memory、storage、net、ability、base、system、processes、faultlog、kernel、hilog、stack
-------------------------------[cpufreq]-------------------------------
-------------------------------[cpuusage]-------------------------------
-------------------------------[memory]-------------------------------
-------------------------------[storage]-------------------------------
-------------------------------[net]-------------------------------
-------------------------------[ability]-------------------------------
-------------------------------[base]-------------------------------
-------------------------------[system]-------------------------------
-------------------------------[processes]-------------------------------
-------------------------------[faultlog]-------------------------------
-------------------------------[kernel]-------------------------------
-------------------------------[hilog]-------------------------------
-------------------------------[stack]-------------------------------
从如上的导出的信息可以看出可以分析定位系统的故障异常问题，但是信息量巨大，需要学习各种信息分析的能力。
