Min step: An additional lower limit for the step parameter of Prometheus range queries and for the $__interval variable. __name__is a reserved word for a metric name. 除了label_replace以外，Prometheus还提供了label_join函数，该函数可以将时间序列中v多个标签src_label的值，通过separator作为连接符写入到一个新的标签dst_label中: best practices. But as question is stated, I simply can't figure out how to drop parts of the "index" label so I can group by only the first parts and not the whole full label value. How can this be done with a Prometheus query?
