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
1.
2.

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%
1.

2.直接打开如下图

需要使用解压工具使用提取功能

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
1.
2.

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
