将sysstat工具包移植到嵌入式linux设备(cifsiostat iostat mpstat pidstat sadf sar tapestat命令移植)

    Linux 下的性能分析，包括CPU使用情况，内存使用情况，IO状态等等与系统相关的状态，少不了要使用 sysstat 工具包中的命令，它包括：cifsiostat  iostat  mpstat  pidstat  sadf  sar  tapestat 七条命令。 sysstat 服务启动后，它会自动每个10分钟收集一次系统状态信息，并将它们存储到 /var/log/sa目录下。每天一个文件，文件名分别是sa01, sa02,... sa30..  但是对于嵌入式设备，一般的busybox里面不会包含sysstat里面的命令，或者说是这些命令有些功能已经被裁减了。为了更好的分析嵌入式设备的状态和性能，可以将sysstat工具包里的命令移植到嵌入式设备中。

    在不同版本的linuxPC机上安装，可以直接参考gihub上readme上的介绍就可以。

3.移植

    sysstat的configure文件默认是使用GCC编译的，需要更改为我们所需要的交叉编译工具。我使用的交叉编译工具是：arm-hisiv300-linux-gcc

3.1获取源代码：

git clone git://github.com/sysstat/sysstat

3.2配置configure

3.2.1配置configure生成Makefile,执行下面命令：

CC=arm-hisiv300-linux-gcc ./configure --host=arm --cache-file=home/biao/test/iostat/sysstat/cache_file_0 --prefix=/home/biao/test/iostat/sysstat/biao  --exec-prefix=/home/biao/test/iostat/sysstat/biao

上面这条命令解析：

CC=arm-hisiv300-linux-gcc  设置交叉编译工具，这个必须放到./configure 之前，不然不会生效

--host=arm     设置主机类型，这个必须设置，否则会出现configure 错误

--cache-file=home/biao/test/iostat/sysstat/cache_file_0  设置缓存文件

--prefix=/home/biao/test/iostat/sysstat/output   设置输出文件目录，需使用绝对路径

--exec-prefix=/home/biao/test/iostat/sysstat/output 设置可执行文件目录，需使用绝对路径

执行完上面语句，会生成Makefile文件

执行结果如下：

biao@ubuntu:~/test/test/sysstat$ CC=arm-hisiv300-linux-gcc ./configure --host=arm --cache-file=home/biao/test/iostat/sysstat/cache_file_0 --prefix=/home/biao/test/iostat/sysstat/output  --exec-prefix=/home/biao/test/iostat/sysstat/output

sudo make

sudo make install

执行完上面命令，会在configure时设置的目录中生成所有的输出文件，包括库文件和可执行文件：

biao@ubuntu:~/test/iostat/sysstat/output$ ls

4.结束

   可以直接将bin 文件中的可执行文件拷贝到嵌入式设备中去就可以直接执行。有些命令可以直接使用，有些命令需要打开sysstat功能才能使用，比如sar命令。打开sysstat 命令的方法是：

[root@localhost ~]# chkconfig --level 35 sysstat on
[root@localhost ~]# chkconfig |grep sysstat
sysstat         0:off   1:on    2:on    3:on    4:on    5:on    6:off
