安装iostat和mpstat工具包

安装好OSW，启动时发现缺少iostat和mpstat两个工具包，这两个工具包含在sysstat包中，手动来安装下吧

[root@localhost ~]# iostat

-bash: iostat: command not found

[root@localhost ~]# mpstat

-bash: mpstat: command not found

在系统观盘中找到sysstat包，然后使用yum或者rpm命令进行安装，sysstat包中包括iostat,mpstat,sar,sa

[root@localhost ~]# rpm -ivh sysstat-7.0.2-3.el5.x86_64.rpm

warning: sysstat-7.0.2-3.el5.x86_64.rpm: Header V3 DSA signature: NOKEY, key ID 37017186

[root@localhost ~]#

安装后，使用命令测试。

[root@localhost ~]# sar -u 10
