I have two prometheus metrics nodes_threadpool_rejected , nodes_indices_index_total and want to perform

nodes_threadpool_rejected/ nodes_indices_index_total

left side metric nodes_threadpool_rejected has nodename and right side metric nodes_indices_index_total has node. I want to match nodename with node when doing /

Is this possible ? I read https://prometheus.io/docs/prometheus/latest/querying/operators/#vector-matching but no clue
