os.loadavg()

• Returns: <Array>

os.loadavg()方法返回一个数组,包含1, 5, 15分钟平均负载.

平均负载是系统活动的测量,由操作系统计算得出,表达为一个分数. 一般来说,平均负载应该理想地比系统的逻辑CPU的数目要少. 平均负载是UNIX相关的概念,在Windows平台上没有对应的概念. 在Windows上,其返回值总是[0, 0, 0].

• Returns: <number[]>

The os.loadavg() method returns an array containing the 1, 5, and 15 minute load averages.

The load average is a measure of system activity, calculated by the operating system and expressed as a fractional number. As a rule of thumb, the load average should ideally be less than the number of logical CPUs in the system.

The load average is a UNIX-specific concept with no real equivalent on Windows platforms. On Windows, the return value is always [0, 0, 0].
