这个问题在unix os guide中说的很含糊(或许是我的理解有问题)。对于CPU Busy这个属性值的定义大家都知道是System CPU和USer CPU占用的CPU时钟周期之和。
我们来看看user guide中的解释:
CPU Busy [CPUBUSY]: The sum of the System and User CPU attributes in percent. Valid entries are numeric values in the range 0 to 100, including the use of *AVG, *MAX, *MIN, *SUM, Count, and Value functions.
这是CPU Busy的解释
System CPU [UNIXSYSCPU]: The percentage of CPU time devoted to executing UNIX system kernel code. Valid entries are numeric values expressEd as a percentage in the range 1 to 100, including the use of *AVG, *MAX, *MIN, *SUM, Count, and Value functions.
这是SystemCPU的解释
User CPU [UNIXUSRCPU]: The percentage of processor time devoted to user processes. Valid entries are numeric values expressed as a percentage in the range 0 to 100, including the use of *AVG, *MAX, *MIN, *SUM, Count, and Value functions.
这是Uer CPU的解释
仔细看这些属性的解释好像是采集到的是计算后的值,而非瞬时值。那么在situation公式里面怎么就看不到有AVG,MAX,MIN等选项呢?那么默认的是那种概要值呢?
