While reading other document, I found that both time series need to have
matching labels.
I have an extra label "region" for all metrics.
Aggregate on denominator "mode" doesn't make it work
node_load5{instance="host"} /
sum without (mode)
(count(node_cpu_seconds_total{instance="host",mode="idle"}))
The following query works thought
sum without (instance, job, region) (node_load1{instance="host"}) /
sum without (mode)
(count(node_cpu_seconds_total{instance="host",mode="idle"}))
but I really don't understand why
