一点说明:

sar命令是要sysstat-4.0.7-3.rpm(redhat 9.0是这个,其它版本作相应改变)

Target：是要执行的脚本
Xsize：生成图表的横向宽度（最大600）
Ysize：生成图表的纵向高度（最大200）
Title：标题
Ytics：纵向划分为几个块（格子）
MaxBytes：图表纵向数值的最大上限,如果此值小于LegendI,则输出的LegendI等于Legendo,Legendo则等于零!
PageTop：页面上面的提示
kilo：一般是写1024，如果需要的话，是1000在计算机里的单位
LegendI：从SHELL返回的数据中的第一个
LegendO：从SHELL返回的数据中的第二个
Options：一般后面跟growright，表示图表向右延展
