pipers:在PromQL查询或代码中使用管道表达式！

吹笛者 在PromQL查询或代码中使用管道表达式！ 例如，以下查询... sum ( irate (node_cpu_seconds_total{ instance = ~ " $node:$port " , job = ~ " $job " }(node_cpu_seconds_total){ mode = ' idle ' }[ 5m ](node_cpu_seconds_total{ instance = ~ " $node:$port " , job = ~ " $job " }(node_cpu_seconds_total)))) / count ( count (node_cpu_seconds_total{ instance = ~ " $node:$port " , job = ~ " $job " }(node_cpu_seconds_total)) by (cpu)
