如何比较所有大于平均值的值? [英] How do I compare select all values larger than their average?

问题描述

假设我有以下数据

my_metric{instance="0"} = 1
my_metric{instance="1"} = 2
my_metric{instance="2"} = 3

我有兴趣查询大于所有指标平均值的所有指标.my_metric >avg(my_metric) 似乎不起作用.我的猜测是因为 avg(my_metric) 不是标量，而是一个 1 元素向量.有人能指出我正确的方向吗?

I'm interested in querying all metrics that are larger than the average of them all. my_metric > avg(my_metric) doesn't seem to work. My guess is that it's because avg(my_metric) isn't a scalar, but a 1-element vector. Could anyone point me in the right direction?

推荐答案

  metric 
> ignoring (instance) group_left  
  avg without(instance)(metric)
