OpenTSDB 的 Rate 函数的单位是什么?
What are the units for OpenTSDB's Rate function?
假设我有一个每秒递增一次的字节计数器指标。如果我绘制它,我将得到一个单调递增的图。 Y 轴标记为 'bytes'.
我想绘制计数器的变化率,因此单击 "Rate" 复选框。速率是每单位时间的变化,但那个单位是什么? Y轴应该有什么标签?
Rate 功能是 OpenTSDB 查询功能。根据 OpenTSDB docs
The rate is the first derivative of the values. It's defined as (v2 -
v1) / (t2 - t1). Therefore you will get the rate of change per
second. Currently the rate of change between millisecond values
defaults to a per second calculation.
